1. Presentation
WinPro®/ MX62 is a stationary control system to be used in combination with a
variety of detectors for continuous detection of combustible gases, toxic gases
and oxygen.
Main features are a high reliability and flexibility. The flexibility refers to all
areas, as there are free programmability, installation of relay and analog output
modules and the optional installation in wall-mounted housings, 19 inch racks or
control panels.
The modular components allow extension for up to 64 channels, 128 relays, 64
analog outputs and the optional use of an LCD module with data logger or
profibus module, making the gas detection system suitable for all applications.
The complete system and all required modifications can be set by the software
ConfigPro. This software is detailed separately.
2. System configuration
The system consists of a controller module plus various other modules linked by
digital busses. The basic configuration is as follows:
Analog input module (AEM)
Controller module (CM)
LED module
LCD or logo module
The AEM converts the 4-20 mA signal of the detectors into digital bus signals to
be transmitted to the CM. In the CM the signals are evaluated and separately
indicated for each channel according to the respective presettings.
One AEM and one LED module are designed for eight channels each.
The CM can directly be employed for 64 channels on different input and output
modules.
In addition the following modules can be integrated into the system as required:
Basic relay module (RBM)
Extension relay module (REM)
Analog output module (AAM)
Loop module (LOOPM)
LCD data logger module

Page 12
Profibus module (PBM)
Analog input extension module (AEAM)
LCD copy module
MIMIC module
Each RBM provides eight relays to be freely allocated. The REM allows the
addition of eight relays with a minimum of space.
The AAM provides either 4-20 mA or 0-10 V outputs.
The AEAM can be used in combination with the AEM to connect smoke
detectors at WinPro/ MX62.
All measured values and informations can be displayed with the LCD module
and stored by a data logger.
2.1. Description of Modules
2.1.1. Controller module (CM)
The CM is the central control unit of the system for all 64 channels of
maximum configuration. Two 16 bit micro controllers process the signals
of the input modules redundantly.
The status of the relays and the output signals are transmitted to the relay
and analog output modules by a redundant bus.
Another bus transmits the signals to the LCD and LED module. For safety
control the CM also contains relays to signal system errors, emergency
operation and service mode.
By means of an RS232 interface, the entire system can be configured and
all data can be visualized on a PC.
A Centronics interface is available for connection of a printer.
2.1.2. Analog input module (AEM)
The detectors are connected to the AEM. Each module accommodates up
to eight detectors with 4-20 mA signal output and provides an additional
RS485 interface per channel.
By this interface, communication can be established in service mode
between a PC, connected to the CM, and the respective digital detector.
Up to eight AEM can be connected to the CM. An address between 1 and
8 is allocated to each module by rotary switch.

Page 13
2.1.3. LED Module
The status of each channel is indicated by LEDs. Each detector can be
connected to any channel.
Operation of the buttons for the respective channels displays additional
information about the connected detector on the LCD module and triggers
further channel functions such as alarm suspension, operational test,
channel disconnection and calibration mode.
The LED module consists of an LED panel for 16 channels and one or
two PCBs for eight channels each.

2.1.4. Basic relay (RBM) and Extension relay module (REM)
A RBM has eight relays and can be extended by eight relays with a
pluggable REM.
Redundant triggering of the relays is done via two 8 bit micro controllers.
Free parameter setting of the relays with the help of software ConfigPro
meets all individual requirements:
Open and closed circuit operation
Grouping
AND / OR logic operation
Voting
ADVANCED relay functions
Time-delay and slow Release
Buzzer relay function
Relay reproduction

Page 14
ATTENTION!
It is not allowed to use the ADVANCED relay functions in a safety related
ATEX application with measuring function for explosion protection or a SIL
application.
Up to eight relay modules with a total of 128 relays can be integrated into
the system. The redundant, opto-isolated RS485 bus allows spatial
separation (up to 800 m) of the modules and control unit.
An address between 1 and 8 is allocated to each module by rotary switch.
Open circuit:
The relays are activated as soon as the respective status is recognized, i.e.
the relay inductor pick up.
Closed circuit:
The relays are activated in normal operation, i.e. the relay inductor have
picked up, and will be deactivated in case of alarm, i.e. the relay inductor
will be released.
2.1.5. Loop module (LOOPM)
The LOOPM for WinPro®/ MX62 offers the possibility to build a
network of digital detectors or to record signals of any standard 4-20 mA
detector by means of AEM connected to the LOOPM.
The LOOPM can be employed in three different configurations:
a) As regular Loop Module with up to 16 digital transmitters (e.g.
TBGW EX) linked to the closed loop (address 1 to 16).
When using this type of configuration, no additional AEM can be
connected.
b) With one AEM and up to 8 digital detectors linked to the loop
(address 9 to 16).
c) With two AEM for connection of up to 16 standard 4-20 mA detec
tors. In this case, digital detectors cannot be linked to the loop.
Connection of digital detectors to the loop is realized by junction boxes
(part no. 81090). Junction cables must not exceed a length of 30 cm.
ATTENTION!
When connecting digital detectors to the LOOPM, the current output (4-20 mA)
inside the detectors has to be blocked with a shunt resistance of approx. 180
ohms between ground (GND) and current output (4-20 mA).
Furthermore, the two jumpers inside the detector for the bus end resistance
(jumpers for RS485, next to the connection for power supply) need to be
removed.

Page 15
2.1.6. Analog output module (AAM)
The employment of up to eight AAMs with a total of 64 outputs allows
transmission of detector signals (4-20 mA or 0-10 V).
An address between 1 and 8 is allocated to each module by rotary switch.
ATTENTION!
Though the AAM has two microcontrollers, only one controller is able to
transmit data to the outputs. This is generally done by controller B. Since this
will block transmission of measured values by controller A, same will be
considered as faulty and the LED for fault will light up in red.
Should controller B be faulty, controller A will take over transmission of
measured values to the outputs. In this case, the LED of controller A will light
up in green and that of controller B in red.
2.1.7. LCD module
The system WinPro®/ MX62 can be equipped with a graphic LCD
display (240 x 128 pixels) showing information of measuring points, all
relevant system parameters, system events and histograms.
The LCD module is provided with an integrated data logger with a storage
capacity of up to 64 MB.
2.1.8. Logo module
If the optional LCD module is not used, the logo module will serve for
display of the four LEDs indicating the status of the system. The logo
module consists of the logo panel plus pertaining PCB.

Page 16
2.1.9. Analog input extension module (AEAM)
The AEAM is intended for the connection of smoke detectors. It is
possible to connect up to 8 smoke detectors at each AEAM.
The AEAM is an extension module and has to be plugged on the AEM.
ATTENTION!
It is not allowed to connect gas detectors to the AEAM.
2.1.10. LCD copy module
The LCD copy module is a modified LCD module. It offers the possibility
to connect additional LCD displays (max. 30) to the display bus of the
WinPro®/ MX62.
The LCD copy modules have to be use only in combination with a
standard LCD module (software version 2.05 or higher in needed).
In opposition to the LCD module it offers no data logging functionality
and any interaction.
In normal operation mode it displays the logo of the company and the
date. The backlight is off.
Each alarm on one of the 64 channels will be displayed by the LCD
module and the LCD copy modules. The backlight will be activated
automatically.
If there is more than one alarm at the same time, the affected channels will
be displayed alternating for ten seconds.
The LCD copy module is subordinated to the LCD module. During
interaction with the standard LCD module, e.g. a user wants to see
information about one channel by pushing the channel button, the LCD
copy module still shows the logo of the company, even if there is an
alarm.
System messages are displayed by four LEDs.
The LCD copy modules are addressable (software V 2.18 or higher). The
addresses are set during production. By setting a address it is possible to
display the alarms selective. Modules with the address 0are showing all
messages. The configuration of selective messages has to be done by the
software ConfigPro.
2.1.11. MIMIC Module
It is possible to copy the LED modules by using MIMIC modules.
The MIMIC module has to be connected to the display bus of the system
WinPro®/ MX62.

Page 17
Each MIMIC module copies exactly one LED module. It is possible to
connect a further LED module to the MIMIC module or to copy the
primary LED module by using the open collector outputs of the MIMIC
modules.
The MIMIC Module just shows status information of the channels.
The buttons of the LED Module are deactivated.
2.2. Redundancy of WinPro / MX62
The redundant structure of the system WinPro®/ MX62 means that the complete
safety functions are provided twice. From conversion of analog signals into bus
signals to evaluation in the CM and relay connection, any single error will not
lead to failure of the safety functions.
In addition, the two controllers of the CM continuously compare with each
other. Thus, not only single-error-protection is achieved but also maximum
availability.
To fulfill maximum safety criteria, the whole safety chain from detector to relay
must be provided twice. Linking of detectors and relays can be carried out with
the software ConfigPro.
2.3. Control Pane of WinPro / MX62
The control panel consists of at least one LED module indicating 16 channels
and one logo module displaying the four LEDs for status monitoring.
Three further LED modules can increase the number of channels to 64. The
LED modules are identified by letters of A to D. The channels are always
numbered consecutively from 1 to 16.

3. Operation of the System WinPro / MX62
During normal operation, the WinPro®/ MX62 continuously processes signals
of the connected detectors.
Besides, WinPro®/ MX62 can enter into other modes for servicing or in case of
malfunction. This chapter describes the various operating modes and the
respective system performance.
3.1. Channel and System Information
As a standard, WinPro®/ MX62 provides optical LEDs for the display of
channel and system information.
Channel information:
Channel information refers to the respective detectors. The indication is done by
seven LEDs for every channel on the LED module.

Page 20
These blinking LEDs indicate a certain system status. For detailed description,
please see:
System failure (see chapter 3.6)
Single mode (see chapter 3.5)
Service mode (see chapter 3.4)
On the CM a separate relay output is allocated to each of these three modes.
The blinking LED Battery signals power failure, which provides an emergency
power supply (optional).
Information of channel and system status can also be gained from the relay and
analog transmitter signals.
In the following chapters the relay modules RBM and REM are explained.
Details are given assuming a 1:1 relation between signal and relay
output. Please note that this relation might not be valid when using the
program ConfigPro to link several alarms or fault alarms in an installed
system.
3.1.1. ISA procedure (slow flashing channel LED)
For a better differentiation between “old” and “new” channel information
it is possible to activate the ISA procedure by the software ConfigPro.
If the ISA procedure is activated, each new channel information will be
shown by a slow flashing LED. After acknowledgement by the user the
respective LED will light continuously or will set off (see chapter 3.3.7).
If the ISA procedure is not activated, a new alarm or a new channel fault
is leading directly to a continuous lightning of the respective LED.
In this manual the description of the status of the channel LEDs is
done for the deactivated ISA procedure.
3.1.2. General buzzer relay
Beneath the three system relay outputs on the CM there is a further relay
output for system information. This relay is activated for a short time
(about 1 s) and is configurable by software as follows:
General buzzer relay:
The relay will be activated at each new alarm. This means that each new
alarm can be indicated visually or acoustically. and/or
Warning for deactivated channels:
If the service rotary switch on the CM is moved from position 4
(activating/deactivating channel, see chapter 3.4.4) to another position and
