Safety symbols used in these instructions
¯These symbols (triangle and arrow) emphasise safety
instructions and warnings.
¯If you fail to follow these instructions, severe injury to
personnel or extensive equipment damage can result.
Where do I find the
warnings?
General safety instructions are given in this chapter. Special
safety instructions and warnings are positioned at the
appropriate locations in these Service and Diagnostic
Instructions and on the service and diagnostic cards.
The instructions and warnings are not only given in cases
where danger could directly occur from system devices.
The warning symbol is also used when improper use or
settings could result in direct danger. It is used regardless of
whether the direct danger is reduced or eliminated by other
mandatory safety devices.
¯Observe other safety notices of customer-supplied devices
and plant parts. You can find the associated symbols and/or
instructions in the documentation for these devices or on the
devices themselves.

1.2.2
Use according to regulations
General applications
Universal and standard process units are used for regulation,
control and monitoring in heating, ventilation and air
conditioning plants of building management systems.
Depending on process unit and configuration, limitations can
exist (e.g., from certain standardised and pre-project systems
and OEM customer solutions).
Decisive for all applications are the technical specifications
contained in the produce-specific documentation, the
individual data sheets and other technical documentation
provided by Landis & Staefa.
Use with other
components
Universal and standard process units can be used in
connection with products of other manufacture, provided such
products are supplied or recommended by Landis & Staefa.
Prerequisite:
Within the scope of the overall configuration, all safety
directives and technical specifications of the non-Landis &
Staefa manufacturers are observed. This applies to all
stages of product use (preparation for use, application and
service).
The connection or integration of products of other
manufacturers not specially recommended by Landis and
Staefa is also possible.
Prerequisite:
The safety and other technical requirements of the entire
plant and of its individual components must be complied
with.
Proper use
1-10
For flawless and safe system operation, requirements in terms
of storage, transportation, assembly, installation,
commissioning, operation and maintenance as well as service
and diagnostics must be satisfied in a proper manner. “Proper
manner” means that all conditions, specifications and notes
given in relevant documentation must be observed.
Service and Diagnostic Instructions
Important notes
Landis & Staefa
01.1998 / CM2B8205E
¯An increased safety risk exists if the system (process units
and connected system components) is not properly or
correctly used. In such cases, injury to persons and/or
damage to equipment may occur from the plant (and not from
the controller itself).
1.2.3
Requirements for commissioning and service
personnel
] Scope and target groups of this Service and Diagnostic
Instructions were already mentioned at the beginning of this
chapter.
These instructions contain all the information required for use
of the service and diagnostic cards in the process units
specified.
For the proper use of the system associated with the
respective process units, please refer to the relevant system
documentation. If components of other manufacturers are
used, additional documentation is required.
Qualifications
Commissioning and service personnel must first become
familiar with both general and local regulations, and must have
knowledge of the plant that is appropriate for the application
under consideration.
In addition, special product and service knowledge is required
to properly perform all commissioning, diagnostic and service
work. In particular, expert knowledge is essential in the event
of faults and in the case of large plants having extensive
communication capabilities.
¯Commissioning and service work must always be carried out
by Landis & Staefa service staff or authorised specialists who
have successfully completed appropriate Landis & Staefa
product training courses.
Potential safety risks and dangers must be known. The notes
on safety given in the various documents must be understood
and implemented.

1.2.4
Active and passive safety
Active and passive safety are product or system related
conditions.
Safe status is either actively ensured by the product itself
(referred to as intrinsic safety, that is, safety designed into the
system), or the product has passive safety characteristics
requiring that safety be continuously exercised by the operator
during operation.
Active system safety
Active safety depends on the process unit, the connected
components and the overall configuration of the plant. It is
achieved as follows:
– By having software in compliance with safety (self
diagnostic, plausibility tests, process monitoring, shutdown
in the event of severe faults, data buffering in the event of
power failures (loss of RAM data), general data protection
(EEPROM), etc.)
– By having hardware in compliance with safety
(monitoring for undervoltages, voltage drops, voltage
failures, short circuit resistance, protection against incorrect
wiring, etc.)
– By having a defined switch ON following voltage failure
without risks
– Construction in compliance with safety (e.g., use of
safety extra low voltage with safe mains separation
according to EN 60730).
Passive system
safety
Passive system safety is enhanced by:
– Training the commissioning and service personnel by
Landis & Staefa (proper use of devices; compliance with
safety regulations)
– Instructing the operator, which also includes safety
considerations
– Formatting all documentation in compliance with safety
(instructions, handbooks, and operating, service and
diagnostic cards all have associated safety directives.)
] For more information on system safety, please refer to the
data sheets of the individual units.

General notes on safety
The universal and standard process units are state-of-the-art
products and offer the kind of safety that can be rightly
expected under all circumstances.
Flawless and safe operation presupposes that storage,

1.2.6
Notes on safety relating to certain functions
¯The following notes only represent a certain part of all safety
notes to be followed. Please pay attention to all notes on
safety given in the relevant product documentation of Landis &
Staefa and in the documentation provided by the suppliers of
other equipment and devices.
Program stop
¯During a cold start, during a diagnostic reset and when the
program is stopped, (page 249, line 12), the plant is shutdown.
Note that then all regulation, control and supervision functions
are disabled. In such situations you must ensure that
personnel cannot be injured and that damage to equipment
cannot occur.
Command output
¯When manually initiating a switching or positioning command
(point test, page 246, lines 5 and 10), you must ensure that
persons cannot be injured and that damage to equipment
cannot occur. Continuously monitor the plant while carrying
out all switching actions and checks.
Controller settings
¯Wrong settings on some of the lines of the operating and
commissioning cards may lead to dangerous situations if, at
the same time, safety devices supplied by others are
inoperative. Observe the safety notes given on the cards.
¯Observe the maximum permissible temperatures for underfloor and ceiling heating systems.
Commissioning
¯Prior to commissioning, all mandatory safety devices must be
correctly installed and be operative. For example, set the
thermal reset limit thermostat, safety limit thermostat, boiler
control thermostat, etc., to their correct levels.
1-16
Service and Diagnostic Instructions
Important notes
Landis & Staefa
01.1998 / CM2B8205E
Manufacturer
specifications
¯Whenever you make settings, observe the specifications
supplied by the manufacturers (boiler, burner, etc.). Also
observe the limit temperatures (minimum/maximum) of the
boilers and the burner’s switching differential. The boiler’s
thermal reset limit thermostat must operate independently.
The setting of the maximum boiler temperature on the process
unit never substitutes for the mandatory safety devices
delivered by others.
¯Only select the burner type when the boiler is shutdown.
Preparing
¯If the domestic hot water is set too high, there is the risk of
domestic hot water
scalding on the user side. In the case of domestic hot water
heating with heat exchangers, observe the maximum
temperatures of the heat exchanger.
¯Always switch OFF the power supply if you wish to remove the
process unit from its housing.
Normally closed
contact
Impulse module
¯In the case of I/O modules with relays, please note:
Any devices connected to normally closed (NC) contacts are
immediately operational as soon as the process unit loses
power or if the P-bus fails. This means that the modules can
no longer be controlled.
¯If the P-bus fails, impulse modules PTM1.2Q250-P and
PTM1.2Q250-3P maintain their initial state (Q11/Q12 and
Q21/Q22 closed).
Bistable relays
¯If the P-bus fails, the bistable output relay of switching module
PTM1.2Q250B maintains its last switching position.

1.2.7
Operational hazards
No intrinsic system
hazards
If properly used, assembled, installed, commissioned,
operated and serviced, the process unit and connected
components pose no direct operational hazards.
¯Certain risks in the plant remain if instructions relating to
parameter settings of limit values specified in the
documentation are not observed.
However, the remaining risks can lead to damage only if,
along with incorrect settings, the safety devices specified for
the site are inoperative or not present.
¯There is a possibility of other operational hazards caused by
plant components and/or plant parts. Refer to the plant
documentation and technical literature provided by the
relevant suppliers. Observe the warning instructions in the
plant and on the products themselves.
1.2.8
Safety devices
Safety of units
Among other items, the safety of the units is ensured by:
– Safety extra low voltage 24 VAC (SELV to EN 60730)
– Microfuses in the module supply block
– Prefuses for the I/O bars (not part of the system)
Plant safety
Plant safety is also assured from the system side by:
– The evaluation of plant-specific signals (e.g., STB safety
–
chain, RM feedback signals depending on project type)
Data security for settings and plant data.
] For plant safety, also refer to the section " Active and passive
safety " in this chapter.
¯Upon any hazard, immediately activate the EMERGENCY
OFF switch or switch OFF the plant’s main switch!
Then take emergency actions!

Packaging, storage and transport
Under normal circumstances, service staff have little to do with
the issues of packaging or transportation or with storage of
devices.
Nevertheless, a few hints follow which can help in case a
device must be shipped or otherwise transported.
¯Important: Do not allow the transported devices to be exposed
to mechanical and climatic stresses. Adhere to the transport
and environmental conditions specified in the technical data.
Use the original packing of Landis & Staefa or supplier if
mechanical and climatic stresses are expected (as common in
the EU) during transportation.
Use original
packaging
Never ship or store the units unprotected. Dust or foreign
objects may enter the units through ventilation openings. For
this reason, also keep front covers closed.
Protect against
mechanical damage
Avoid excessive mechanical strain on the package from the
outside (e.g., by sharp or blunt objects). Stack packaged units
only if you are certain the packages can carry the weight.
Transport under
difficult conditions
In the case of transport under difficult conditions, (e.g., on
open vehicles, under extreme vibrations or on ships, etc.), use
additional or more rigid packaging to compensate.
Storage
Store the devices so that harmful environmental conditions will
have no effect. Ongoing and abrupt temperature changes
should be avoided. Such conditions are especially harmful if
condensation occurs.
¯The limit values specified in the technical data (allowable
environmental temperature, humidity, vibrations, EMC, etc.)
always apply for storage and transport also.
¯Landis and Staefa does not assume any responsibility for
damages resulting from improper packaging, storage and
transport.

Environmental protection, disposal
1.4.1
Environmental protection during operation
No harmful effects
During operation, the system components do not cause any
directly known environmental damage.
¯To be sure, the unit has an indirect effect on the emissions of,
for example, a heating plant. The lower the energy
consumption—without sacrificing comfort—the more efficiently
and environmentally friendly the entire plant functions.
Optimisation
functions
With the consistent implementation of optimisation functions in
the plant being controlled, considerable amounts of energy
can be saved. The process units offer an array of such
functions.
Informing the user
Commissioning or service personnel should give appropriate
instructions to the user. By following certain rules, the user can
significantly contribute to environmental protection and, at the
same time, create financial benefits.
Energy savings start where information about energy saving
measures reach the user, e.g.:
– Setting correct setpoints (heating) without sacrificing
comfort
– Correct settings for building-specific parameters
– Utilising optimisation functions of the process unit
– Correct settings for weekly time switches and yearly clocks.
– Room temperature setback when the building is
unexpectedly unoccupied
– Informing the operator about possible plant extensions
aimed at saving additional energy (e.g., additional
detectors)

Notes on disposal
Information about disposal at the end of a product’s service life
is also aimed at the user.
Comment
The process units offer significant environmental benefits not
only during operation, but also during production of individual
components, where the manufacturer ensures that
environmental impact is minimised.
The user has a considerable influence in keeping the
environmental impact low when it comes to the final disposal
of products.
Observe the following items when disposing defective
components or products at the end of their service life:
Disposal
•
Dispose of items properly, that is, separate parts and
components according to the different categories of materials.
The aim should be to recycle as much material as possible,
while minimising environmental impact. For this reason
proceed as follows:
– First remove potentially harmful components and
substances from the unit and dispose of them separately.
Such items include, for example, batteries, LCD displays
and components containing mercury
– Them separate the other parts according to the different
types of materials and prepare them for recycling.
•
Observe any possible instructions on materials concerning
their disposal.
For example, the cards of the service diagnostic set and
possibly other operating cards are made of polypropylene, an
environmentally friendly plastic material that can be easily
disposed of in incinerator plants.
Landis & Staefa recommends recycling.

•
Never throw electrical or electronic scrap in the garbage Make
use of environmentally friendly ways to return such scrap to
the supplier or manufacturer, or get the job done by a
specialised disposal company, exchange service, etc.
Always dispose of items in an environmentally friendly manner
in accordance with state-of-the-art disposal and recycling
techniques.
¯Should you encounter any disposal problems, please contact
your supplier, a disposal company or Landis & Staefa directly.
We will assist you in the orderly disposal of your system

3.2
Functions of the units
Please refer to the " Operation " chapter for the meaning of the
operating and display elements and for information on the
operation of the process units.
The key features and functions of the process units are
described in the " System overview " chapter.
3.2.1
Basic functions of the process units PRU/RWP/RWM
Digital processing
All process units feature DDC and have digital inputs and
outputs for the measuring variables and manipulated
variables. Microprocessor (signal handling) and FEH controller
(peripheral functions) are the major hardware components
that provide the basic functions.
Plant program
The application-specific plant operating program is contained
in plug-in type program cards and modules. The required
function blocks are taken from the function block library (FBL),
interlinked (configured) and used together with the controller’s
operating program to provide a workable plant program. The
configuration is made on a PC (OS/2 operating system) with
the help of the " UNIGYR Design " or " Autoconfigurator "
programs (UNIGYR EMS40 system software). Saving in a
hardware-specific program card is made on site or better, in
the office.
Input/output
All inputs/outputs from and to the process are provided either
via peripheral I/O units (PRU..., RWPxx) or internal
input/output groups (RWMxx). In that case, the control section
of the process units works with raw values (with no units, data
type, etc.). The conversion to physical variables is made by
the I/O units or the input/output groups.
Communication
The majority of process units can be extended by using cards
or modules for communication with superposed or subordinate
units and stations or for plant extensions in station-to-station
mode.
Please refer to the relevant data sheets for functional and
communication capabilities of the individual process units.
The following sections provide an overview or the various bus
systems and unit interfaces.

CM2B8205E / 01.1998
Service and Diagnostic Instructions
Description of the units
3-15
3.2.2
Process bus
The P-bus (process bus) serves for the flow of information
between the control section of the process unit and the
input/output from and to the plant. This is a process-related
data link within the control panel or between control panels..
Bus structure, signal level, telegram format and data
transmission format are specified in data sheet 8022.
External P-bus on
PRU..., RWPxx
The PRU1, PRU2, PRU10 and RWPxx process units have the
P-bus led to the outside to establish the connection to the I/O
units (I/O modules, I/O compact devices).
The process unit sends its information as addressed
telegrams in digital form to the I/O units and calls the
information from the plant with the help of the I/O units.
P-bus cycle
All telegrams are transmitted serially within a cycle time of 0.5
seconds. Only raw values are transmitted. Raw values have
no units, data type or range assignment.
Master-slave
principle
Data traffic takes place according to the master/slave
principle. The process unit is the master. It delivers switching
and positioning commands to the I/O units and obtains the
plant statuses and values cyclically from the I/O units (polling).
During this process, the I/O units by themselves are inactive.
Addressing
Task of the I/O units
3-16
The process unit can address the I/O units only if the
addresses are set or plugged as specified in the planning
documentation.
The I/O units convert the P-bus signals to plant signals
(output) or process the plant signals to P-bus signals (input).
In addition to level adaptations, the I/O units also take care of
measured value logging. The I/O units perform all input/output
functions at the process level:
signalling – measuring – counting – switching – positioning.
Service and Diagnostic Instructions
Description of the units
Landis & Staefa
01.1998 / CM2B8205E
Data protection
In the event of undervoltage or power failure (AC 24 V), the Pbus traffic is interrupted. The processor system carries out a
saving routine within 20 ms of a functional interruption. The Pbus is passive, and the transmission function is disabled. The
watchdog ensures a defined reset state.
Upon power return, the process unit makes a restart with a
defined startup phase after signals have returned to normal.
The plant is switched on again in a defined pattern by making
use of the I/O units. This ensures that dangerous situations
cannot occur.
P-bus cables
The P-bus consists of three wires:
– Data line (PD, Data) for transmitting the signal telegrams
– Synchronisation line (PC, clock) for the clock signal of the
signal telegrams
– Reference line (PU) with the reference voltage for the data
and the synchronisation line (DC 24 V against system
neutral G0)
Remote P-bus
Normally the P-bus (standard P-bus) has a total length of
maximum 50 m. However, it is also possible to use a remote
P-bus having a total length of 200 m. For a remote P-bus, the
following requirements must be met among others:
– Laying the P-bus lines PD and PC in the form of a singlecore coaxial cable, laid in parallel, with both shieldings
connected to PU (on the process unit and on the I/O unit)
– Power supply for the I/O units (AC 24 V operating voltage, if
required) not from the control panel, but rather from a
separate power transformer at the associated I/O unit
(G/G0 locally on the PTX1.01 module supply dock)
– Connection of system neutral G0 from the process unit to
the I/O units via standard single-core copper wire of
1.5 mm2 diameter.

Service and Diagnostic Instructions
Description of the units
3-17
P-bus loading
The remote P-bus and standard P-bus can be combined. In
such a case the possible length of the remote P-bus is
dependent on the number of connected I/O units and on the
length of the standard P-bus which is laid in normal round
cable.
The total of all I/O points represents the P-bus loading. Lines
11 and 12 of service page 246 give the number of the
maximum permissible and of the actually used load units.
Internal P-bus in
RWMxx PRS10
Process units RWMxx and PRS10 have an internal P-bus
which here too establishes the connection between the
microprocessor’s control functions and the input/output
electronics. With these units, the P-bus is not led to the
outside, since input/output are integrated within the process
unit.
The data traffic between the controller and the input/output
electronics takes place as though using an internal P-bus.

3.2.3
BLN bus
The BLN-bus corresponds to the PROFIBUS according to
DIN 19245. The PROFIBUS (PROcess Field BUS) is a bus for
open communication in the field. With the UNIGYR system,
the BLN-bus is used for the following:
– communication with remote operation between several
Use
PRU and RMC process units (station to station)
– communication between the process unit and an Insight
station (PC having " UNIGYR Insight " communication
software), local or using the telephone network with a
modem.
You can obtain the signal level, telegram format, etc. from
data sheet 8023.
More detailed information about PROFIBUS use is given in
basic document " System handbook " CM2Z8020E.
Token passing
principle
PROFIBUS uses the token passing principle. The token is
passed from station to station in accordance with the following
principle:
– As soon as the authorised station has delivered its own
message(s), or the available transmission time has elapsed,
the station passes the token to the next station.
– When a station receives a token, it becomes the master.
This means it can access the bus. If that station has
messages to transmit, it does so. As soon as it has no more
messages to transmit, it passes the token to the next station
– Within a bus access, the data exchanged are only those
between the actual master station and a receiving station.
Characteristics for
UNIGYR
The following PROFIBUS-characteristics are specified for use
with UNIGYR:
– Bus access via token passing
– Synchronous transmission, bit-serial (recognition of start bit)
in NRZ code

Service and Diagnostic Instructions
Description of the units
3-19
– Transmission (sending or receiving) in one direction (half
duplex operation)
– Time/date synchronisation with broadcast, that is, the
station having the lowest address becomes master and
transmits the time and date values to all other stations.
PROFIBUS
cables
The PROFIBUS consists of four wires which are shielded and
twisted in pairs:
– Wire pairs UP and UN for transmission of data (signal level
according to RS-485)
– Wire pairs UR and UG for remote supply voltage
(UR: positive, UG: signal/power ground)
Both ends of each bus cable must be terminated. See the
System Manual CM2Z8020E for information on the use of bus
terminators and on various bus architectures. The cable
shielding should be connected to ground at both ends.
PROFIBUS (BLN)
on PRU1
For PRU1, the PROFIBUS is connected via communication
sets (PAC1... card, PAS1... submodule, PUX1.1U terminal
base). See further below.
Downloading
configuration data
Before loading the configuration data, the communication card
must be plugged into the process unit and into the Insight-PC.
Downloading must not be made via the SCI, rather via the
PROFIBUS.

3.2.4
FLN bus
In terms of the ISO/OSI layer model and the definition of
interfaces, the FLN-bus corresponds to the PROFIBUS
conforming to DIN 19245, but uses a lower transmission rate
(see the " Technical data " section in this chapter). For the
transmission of object data (temperature values, operational
statuses, messages, etc.), the FLN data profile is used.
Use
The Floor Level Network (FLN) serves for data exchange at
the floor level of buildings. An FLN may consist of several bus
sections. The units connected to the FLN may include:
– 1 active FLN device as master, e.g., PRU2
– passive FLN devices as slaves (RWP80, RWM..., RWI...,
TEC controllers RCE9...)
For data exchange, at least one active FLN unit (master) is
required.
More detail about the FLN-bus is given in data sheet 8026 (for
PROFIBUS repeater, see data sheet 8923).
FLN bus cables
The FLN-bus consist of two wires, shielded and twisted: wire
pair UP and UN for data transmission (signal level to RS-485).
The UP and UN connection terminals on the FLN units made
by Landis & Staefa are galvanically separated from the unit’s
electronics.
The following requirements, among others, must be met with
respect to bus topology:
– The bus lines must be looped via the UP and UN terminals
of the FLN units
– The bus cable shielding must not be interrupted and be
connected to ground at least once in each bus section
– From conduit boxes, there may be single arms with
loopback at the end of the arm, which may also have
secondary arms.
– The two far ends of the bus section must be provided with
PFL1.1 FLN terminators

RMC bus
Use
The RMC-bus (MONOGYR-Bus) connects MONOGYR
individual room controllers and switching devices to the RMC
centre. When connecting to the PRU1 process unit, the PRU1
serves as a MONOGYR control centre.
Communication
principle
After 0.64 seconds, the RMC centre sends a data telegram
over the bus and specifies a destination address. The
controller addressed reads the data and replies by providing a
copy of the data read and of the current control operating
data.
The RMC centre verifies the answer telegram (checks the
checksum). If the transmission is error free, the centre sends
the telegram for the next controller over the bus.
If the transmission was not error-free, the RMC centre sends
the telegram a second time. If the second telegram is faulty
too, the centre sends it over the bus to the next controller.
The communication with switching devices is made in the
same manner.
RMC bus lines
The RMC-bus consists of two wires:
– Data line W for the transmission of the bus signals
– Ground M (M9) as the bus reference signal
The RMC-bus may have a maximum length of 1200 m.
RMC bus
on PRU1
On PRU1 the RMC bus connection is made via the following
RMC bus set:
PAK1.0M

H-bus
Use
The H-bus (heating bus) interconnects up to six RVL5... and
RVP75 heating controllers. All controllers can output and
receive data (station to station). For this purpose, each station
is assigned an address. A control centre is not necessary.
The dialog between the controllers and a control centre is also
possible by using appropriate communication equipment.
The following units can exchange data over the H-bus:
Units on the H-bus
– Heating controllers RVL55, RVL50 and RVP75
– SYNERGYR central unit OZW30
– Communications interface OCI55 (interface with any type of
supervisory system)
– PRU1 process unit as a control centre
Addressing
The address of a heating controller on the H-bus is assigned
by entering the address on the controller and by transferring
the address to the PRU1 process unit or the " UNIGYR Insight "
software package.
H-bus cables
The H-bus consists of two wires:
– Data line D for the transmission of bus signals
– Ground M as the bus reference potential
The cable length may be a maximum of 250 m for each unit
connected to the bus.
H-bus
on PRU1
On PRU1 the H-bus connection is made via the following Hbus set:
PAK1.0H55
H-bus card with terminal base for the connection of
SIGMAGYR heating controllers with bus capability to the
PRU1 (data sheet 8276)
The H-bus set is used in place of the battery card in PRU1.

SCI interface
The serial SCI (Serial Communication Interface) interface is a
local PC interface and a standard component of each process
unit. The SCI channel (V.24/RS-232) is available at the tool
connector on the front of the process unit.
Use
Using a PC, the following is possible with the SCI:
– Communication with one or several process units using the
" UNIGYR Insight " program. This program transfers the
operating and display functions of the process units to the
PC level, provides a pictorial visualisation of the plant
process and affords convenient commissioning and
diagnosis. Alarms are not transmitted to INSIGHT over SCI.
– Configuration (reloading, configuration changes) using the
" UNIGYR Design " program. This software allows the user
program to be configured on site in accordance with plant
requirements (PRU1: standalone only).
SCI is especially suitable for commissioning and service for
standalone units as well as for systems.
Connecting cable
PRU1
From the front, PRU1 can be connected to the SCI and

4.1.2
Operating principle
All operating and display elements and the tool connection
facility are located on the front of the process unit.
Operating panel
The operating panel consists of 12 lines. Each line consists of
text, an LCD line and a button. The text for the various lines is
provided in the form of exchangeable cards (operating,
service and diagnostic cards). This multiplies the number of
operating lines in accordance with the number of cards.
Below the operating panel there are adjusting buttons, LEDs,
the LOC/REM switch and the tool connection facility.
Front cover
The transparent front cover (lockable) protects the operating
panel, the LEDs and the LOC/REM switch. The front cover
contains the first operating page (plant-specific). When the
front cover is closed, the first operating page is activated. The
adjusting buttons and tool connection facility (if required) are
accessible. All other settings are made and displays shown
with the help of the cards when the front cover is open.
Cards and card
compartment
The cards are accommodated in a card compartment behind
the front cover. The compartment can be swung out by
pushing on the slider. Depending on their use, the cards are
complied in the form of sets and, to obtain the function
required, the respective card must be at the top of the set so
that it is visible from the front.
With card reader
Units equipped with the card reader automatically identify the
first page when the set of cards is inserted. For that purpose,
the units have an optical reading device which reads and
evaluates the bar code on the first page. The set of cards
must not necessarily be inserted at a constant speed, but
always in the same direction (downward). After closing the
compartment, the values and functions of the identified page
are displayed. You can then use the page.

Without card reader
If your unit does not have a card reader, you must enter the
page number yourself. After closing the compartment, the
values and functions of the selected page are displayed. You
can then use the page.
Text on the cards
The cards are written in clear text and, depending on type,
may include additional graphics (e.g., characteristic curves),
symbols and warning signs. Usually they are produced to
meet specific requirements. This kind of visualisation coupled
with easy-to-understand, line-oriented format and functionrelated operating structure will assist you in quickly grasping
the information provided by each line.
Alterable and readonly values
Each line of the service diagnostic set has an arrow. A black
arrow means that the value of the respective line can be
changed with the adjusting buttons. A white arrow means that
the value displayed cannot be changed (also see " Symbols " in
chapter 1).
Selecting a line
If a value can be changed, the associated line can be selected
by pressing the line button. The display of that line then starts
flashing. If the display does not flash, the value cannot be
changed.
Adjusting a value
To change a displayed value, press one of the adjusting
buttons [+] or [–] below the display window. The value will
increase ([+] button) or decrease ([–] button) as long as you
hold down the button. The longer you press, the faster the
value changes. Hence, the value can be changed within a
wide range in a short period of time. Release the button as
soon you reach the value you require.
Accepting a value
If a display still flashes, the displayed value has not yet been
accepted. This means that your newly set value is not yet
valid. To accept the new value, press the button of the
selected line again. The display stops flashing as confirmation
that the process unit is now working with your new value.

Aborting the
setting procedure
You can abort the setting procedure to avoid having the
process unit accept your new (still flashing) value. Simply
press the button of the next line your want to work with or
change to the next page. Alternatively, you can do nothing
and let the display flash. In any case, the unit continues to
operate with the previous setting. The display flashes for
another three minutes, whereupon the previous value
reappears.
Adjustable parameters and possible value ranges and
functions of the service diagnostic set are described in
separate chapters for each of the service diagnosis pages.

Display of fault status signals
5.1.1
Plant faults
Plant faults are faults occurring in peripheral devices that the
process unit detects, acquires and stores. Each plant fault
automatically triggers a system fault. A system fault is a fault
in the local process unit or in other connected units.
Fault indication by
ERR LED
If a plant and system fault occurs, the read ERR LED on the
process unit flashes.
Fault indication in
display window
At the same time, with the front cover closed, a common fault
is indicated on line 12. You can pinpoint the source of the fault
using this indication.

Index / display
Each fault is assigned a consecutive number as it occurs, the
so-called index. This index can be changed with the [–/+]
buttons so that the associated fault information appears on
lines 2 to 5 of the display window.
Example: " 1 " means that the information about the first error
on the list is displayed.
Code
Display of error code (error number) of the fault displayed on
line 1. The code displayed gives the cause of the fault in a
certain section of the system.
Example: " E.7 " means " No access to this I/O point "
The " List of error codes " is given in chapter " Page 249,

Acknowledging a system fault
The flashing marker in line 2 of page 249 indicates that the
fault displayed on line 1 has not yet been acknowledged. You
can acknowledge the fault by pressing line button 2. Once the
fault is acknowledged, the marker stops flashing.
Acknowledgement
By changing the index on line 1, you can view the entire error
list. After correcting the cause of the fault, the application
automatically resets the fault entry.
Infrastructural errors, such as invalid dates, writing errors, etc.,
can only be reset by restarting (see page 249, line 12).
Error codes displayed on other lines are fault messages that
occur when accessing the associated data. Such error codes
indicate operating or communication errors and cannot be
acknowledged.

Common enabling
The common enabling function is part of the user program,
This means that it must have been explicitly programmed in
the software.
Common enabling is always required when the fault message
is still present even though the fault has been rectified. Check
whether the operating cards you are using allow common
enabling. If this is not the case, you can use the cold or warm
start function (see service page 249, line 12).
Aditional information on the cold/warm start function is

Diagnosis using operating cards
Make the diagnosis using the plant-specific operating cards if
the following conditions are met:
– Common fault indication on line 12 of the front cover page
– ERR LED flashes
– Fault displayed is not a system fault.
Note
Diagnosis
The common fault indication of the process unit is a software
function, which needs to be implemented by the programmer.
The display is usually on the front page.
1. Read the common fault indication (Index.xx). The index
indicates which input of the common fault block has a fault.
2. Acknowledge the common fault display by pressing line button
12. The ERR LED stops flashing and is not steady on. The
final acknowledgement is made on the operating page of the
respective plant section.
3. Pinpoint the faulty plant section. For that purpose, compare
the index read with the common fault list (on the front or rear
of the front cover page).
4. Insert the operating page of the faulty plant section (and select
it if no card reader is present). Close the card compartment.
5. Read error number (fault message) off the operating page.
6. Determine the cause of the fault. For that purpose, compare
the error number displayed with the information given on the
list having the fault messages (on the front cover page or
operating page).
7. Correct the fault in the plant.
8. Make a software reset at the control panel or initiate common
enabling.
9. If the ERR LED flashes or is steady on, at least one more fault
is present. In that case, repeat steps 1 through 8 until all plant
faults are removed.

Loading and reading the configuration
5.4.1
Loading via SCI
When communicating with standalone stations, please note
the following:
– There is no automatic alarm transmission to the Insight PC
– Reading logged data is not possible.
Limitations
If a serial connection is opened to a PRU1 on BLN, then the
following applies:
Only the " Read and backtranslate code " function is allowed,
because with " Load code " the OV object list is not loaded.
Thus the same limitations hold as for the standalone station.
The object list can be loaded via SCI for PRU2 and PRx1, but
not printer data (user-defined text).
Carry out the following checks before making the download
via SCO:
– Connection of SCI to the process unit:
–
Pin 2 = RxD, Pin 3 = TxD
Check the baud rate:
2400 Baud (PRU1/RWx8x) or 9600 (PRU2, PRx10)
The REM LED must flash while downloading.
If an error occurs while downloading, which is traceable to a
process unit error, the red ERR LED starts flashing.

Loading via PROFIBUS
You can start both of the " Load code " and " Read code and
back translate " actions in the " UNIGYR Insight " or
" UNIGYR Design " programs.
Note that any already existing configuration in the process unit
involved will be overwritten upon loading. Thus pay attention
to the appropriate warning which allows you to abort the
action.
When loading via the PROFIBUS interface, the configuration
data is loaded into the EEPROM of the process unit, and the
KE in the PRU/RMC will be configured (loading the object list).
For PRU1 the object list is loaded only when loading via the
PROFIBUS interface, but not when loading via the SCI.
For additional information about loading, reading and back
translating, please refer to the basic documentation " System

The serial interface is a standard component of the process
unit. It is intended for diagnosis, logging and configuration.
Note the following for operation with both interfaces:
– Both interfaces are normally simultaneously active. This
means that simultaneous communication via both interfaces
is possible.
– When restarting the process unit, the KE (if present) is
selected for the output of fault status signals and other
events. The serial interface serves as a configuration
service interface
– Separate running modes are used for both interfaces (lines
1 and 2)
– With simultaneous communication, please note that for
write operations no preference is given to a particular
interface. The value written last is valid.
For correct communication, settings 2 and 3 on lines 1 and 2
must not be used. Operating mode 3 is for test purposes only.

Point test of the I/O modules
Preliminary remarks
Using service page 246 you can test individual I/O points. It is
thus possible to check the wiring and functions of the plant
during commissioning. Also, you can take a closer look at
faults discovered during system diagnosis.
Examples:
– Checking measured values of temperature
– Output a pump command and check for the feedback signal
There are basically two possibilities for checking an I/O
module:
– Read values and statuses when the program is running
– Enter output commands for an I/O point when the program
is stopped.
9.4.1
Reading
Reading while the program is running
Read the values or statuses as follows when the program is
running:
1. Insert service card page 246 (and select it if you do not have a
card reader). Close the card compartment.
2. Set the module address on line 1. The module type code is
then displayed on line 2.
3. Select the I/O point to be tested on line 3. Lines 4 and 5
display the associated information.
9.4.2
Steps
Command output when the program is stopped
If you wish to make a point test by issuing a positioning or
switching command, carry out the following steps:
1. Stop the program run
2. Carry out a point test
3. Restart the program
9-6
Service and Diagnostic Instructions
Page 246, I/O modules

Stop the program
Interrupt the program run as follows:
1. Insert service card page 249 (and select it if you do not have a
card reader). Close the card compartment.
2. Activate line 12 and enter " 1 " .
3. Press line button 12 until the green RUN LED starts flashing.
The program run is now interrupted.
Note that while the program is stopped, all regulation, control
and supervisory functions are disabled.
Point test
Test an I/O point as follows:
1. Insert service card page 246 (and select it if you do not have a
card reader). Close the card compartment.
2. Set the module address on line 1. The module code is then
displayed on line 2.
3. Select the I/O point to be tested on line 3. Lines 4 and 5
display the associated information..
4. Enter the switching or positioning command on line 5 and
watch for the response. Prerequisite: your selected I/O point is
a switching or positioning point.
You must ensure that no injury to personnel and/or equipment
damage can occur when you give the switching or positioning
command.
Example of a switching command output
Selected module type:
PTM1.4QD for switching
and feedback
(e.g., pumps)
I/O point:
1
Input:
0 (feedback)
Output:
0 (switching command)
Now enter a “1” on line 5 (output). Check on line 4
whether the feedback signal of the pump is logged at
the I/O point.
Input:
1 (feedback)
Output:
1 (switching command)

In a PROFIBUS segment, the station with the lowest address
is always the master clock station. It thus automatically
synchronises the time of day in the other stations.
Time
synchronisation
If a manual readjustment of the time of day is made on any of
the PRU/RMC, a signal is sent to the master clock station from
where it is passed to the other stations in the PROFIBUS
segment. However, no synchronisation is made beyond the
boundaries of the segment.

For PRU2 and PRx10, the data protection function causes the
RAM data to be immediately written to non-volatile memory.
This avoids loss, during commissioning via Insight or
operating cards, of parameter changes made or current
values (e.g., counter values) upon a restart of the process
unit.
This function has no effect for PRU1 and RWx8x. Parameter
changes for these units are directly written into non-volatile
memory (EEPROM). Only current data (e.g., counter values)
are in RAM. These are backed up automatically.
Depending on unit type, such automatic backups are carried
out at various times of day and with different frequencies:

Initial start
After an initial start, both the backup copy and the
working copy are invalid. The configuration must be
reloaded.
1
Cold: cold start
After a cold start, the working copy is invalid. For this
reason a working copy is made from the existing backup
copy (that is, the configuration is reloaded from
PEROM).
Make a data backup if you want to ensure that after a cold
start the same working copy is active as before the cold start.
Data backup is made using page 248 on line 10. When saving
data, a backup copy is made from the current working copy.
Each cold start resets the diagnostic data of the current day.
2
Warm: warm start
After a warm start, the backup copy and the working
copy are valid (but not necessarily identical).
3
Blocked: block start
Block start means that after a cold or warm start the
HVAC interpreter has stopped (program is currently
stopped). The interpreter is stopped if the program
encounters the same runtime error three times within
eight minutes after a restart.
You can also intentionally stop the interpreter if you hold
down line button 12 during power up.
Once the interpreter is stopped, it remains stopped until
you intentionally restart it (by pressing line button 1
during power up), or until a configuration download has
been successfully completed.

Diagnostic reset: reset (set to zero) the diagnostic data
and make a cold start.
All the diagnostic data on page 250 are reset.
During a cold start and each time a diagnostic reset is made,
the plant will be switched off for a short period of time. Note
that this disables all regulation, control and supervision
functions. You must thus ensure that no injury to personnel
and/or equipment damage can occur.

List of suffix codes
Suffix codes can be displayed as information both on a service page and in the error
queue.
Notes on error code 14:
Important
The suffix codes displayed in line 3 in case of error code 14
consist of two individual items of information – the type and
the cause of the last restart. These two items of information
are combined to a three-digit decimal code or four-digit
hexadecimal code in the display.
The information on the type and cause of the last restart are
also indicated in lines 8 and 9 of service page 249. For
reasons of simplicity, we recommend that this information
should be used instead of the suffix code to error code 14
displayed in line 3.
The explanations contained in the following table are based
on the display in lines 8 and 9. Since, however, the output on
local printers and in INSIGHT uses the decimal suffix code, a
conversion table has been included on page 12-21 in the
following.

Notes on error
code 17
Errors associated with the communication interface
(PRU1 base unit and PRU1 communication module).
The error with code 17 an suffix code 40 can occur in PRU1,
PRU2 and PRU10.
The errors with code 17 suffix codes 41 to 52 only occur in
PRU1. They are associated with the FIFO function of the base
unit. Many of these errors were particularly significant during
the development phase and rarely occur now.
The error with code 17 an suffix code 53 can occur in PRU2
and PRU10.

You must change the battery when the marker in the display
window flashes (see error number 16). The process unit
remains operational, however, as long as normal power is
available. The battery should be exchanged as quickly as
possible to ensure that data backup is functional in case of a
power failure.

Battery change for
PRU1
With the PRU1 process unit, the rechargeable batteries
(accumulators ) are soldered in position on battery card
PUG1.1 or on the card of a PAK1.0... bus set.
When commissioning the unit, the battery card must be
transferred from slot space E (storage location) to slot space
C. If the accumulators are discharged, the relevant error
signal appears (marker flashes). The marker flashes until
the accumulators are adequately charged. The charging
procedure has no effect on the functioning of the process unit.
The life expectancy of the accumulators on the card is at least
five years. If they can no longer be adequately charged, you
must exchange the entire card.
When changing the batteries, please refer to Mounting
Instructions M8241.
Used batteries must be disposed of properly.
Never throw them in the fire—risk of explosion!
Never throw them in the garbage!

Change of address
When changing the station address, observe the following:
– Make a warm start after the change. The initialisation and
startup procedure can take a few seconds.
– If the station address does not agree with the address code
on the operating pages, remote operation problems may
occur.
– If you change the station address on a BLN unit providing
data to other units, you will lose the communication link.
Loading the
configuration
When loading the configuration vi the V.24 interface (SCI), the

Printer and modem connections
14.4.1 Printer interface
A printer can be connected to any BLN unit if the appropriate
card is fitted. The printer prints alarm messages and reports.
Each segment can accommodate just one printer.
Printer cable for
PRU1
The product-specific PUW1.7UP printer cable is needed for
the PRU1 process unit. The card used (Set PAK1.1UP... or
PAK1.0M24) automatically recognises if a PRU1 is available
with a connected printer. Enabling the printer interface via a
service card is thus unnecessary.
The PUW1.7UP printer cable cannot be used for the PRU2
and PRx10 process units.
Printer cable for
PRU2, PRx10
A special cable is needed for PRU2 and PRx10. The printer
interface of this unit is so configured that a standard serial
cable can be used.

The PRU1 printer cable has a non V.24 compatible DTR-CTS
connection. This connection is not available with the standard
cable. Handshaking is supported by the software (XON/XOFF)
and by the RTS/CTS control lines (buffer check).
The benefit of the RTS/CTS handshake is that no data is sent
to the printer if the printer is switched off. In this way no
messages are lost.

With PRU2, all interfaces are available on the communication
card (printer and modem).
With PRx10, there is only one optional interface available to

Basic information
All error messages or faults that occur on a slave unit are
acquired as a common fault by the FLN master’s error
identification system and then processed (for display of the
fault, see page 249). This concerns all errors defined in the
FLN data model at " Device Status " .
If a fault (or several faults) occur on a slave unit, the message
" Faulty slave " on service page 249 will be provided with a time
stamp, and the device address displayed as additional
information.
With an FLN slave, all errors in the system base will be
identified, displayed individually on page 249 and entered in
the " Device Status " according to the FLN data model. All FLN
slave faults (Device Status) are displayed as a common fault
on page 252, line 8.
For a diagram on information flow, see next page.

Refresh time
Period of time between two events for data update
(available and adjustable only with RWx8x)
A period of time between 0 and 255 seconds can be set there.
Each time the set period of time has elapsed, an event for
data update is triggered. The value of 0 (zero) means that no
events will be generated.
Presetting: 10 s
For an RWx8x the function is valid for all read values (e.g.,
measured values).
