1.The System WinPro®
The system WinPro® is a stationary gas control unit to be used in combination
with a variety of transducers for continuous detection of combustible and toxic
gases.
Main features are high reliability as well as remarkable flexibility. This flexibil-
ity refers to all areas, such as free programmability and placing of relays and
analog outputs as well as optional installation in wall-mounted housings, 19”-
racks or control panels.
Modular components allow extension of up to 64 channels, 128 re-lays and 64
analog outputs as well as optional use of an LCD module with data logger plus
process and field bus module, making the gas detection system suitable for all
applications.
The complete system and all required modifications can be set by means of the
software ConfigPro.

2.Configuration
The system consists of a controller module plus various other modules linked by
digital bus. Basic configuration is as follows:
•Analog Input Module (AEM)
•Controller Module (CM)
•LED Module
The analog input module converts the 4-20mA of the transducers into digital bus
signals to be transmitted to the controller module where these are evaluated and
separately indicated for each channel according to the respective presetting. One
analog input and one LED module are provided for eight channels each. The
controller module can directly be employed for 64 channels.
In addition, further modules can be integrated into the system as required:
•Basic Relay Module (RBM)
•Extension Relay Module (REM)
•Analog Output Module (AAM)
•LCD Data Logger Module
•Process and Field Bus Module
Each basic relay module provides eight relays to be freely allocated; the exten-
sion relay module allows a further eight relays using a minimum of space. The
analog output module is available for either 4-20mA or 0-10V. Furthermore, all
information and values measured can be displayed via the LCD module and
stored with a data logger.

12
2.1.Description of Modules
2.1.1.Controller Module (CM)
The controller module is the central control unit of the system for all 64 chan-
nels of maximum configuration. The values measured and conveyed to the ana-
log input module are redundantly processed by two synchronously working 16-
bit microcontrollers. Via a redundant bus, the status of the relays and the analog
output signals are transmitted to the relay and analog output modules respec-
tively. Another bus conveys the values measured to the LCD and LED module.
The controller module also contains relays for signalling of system errors, emer-
gency operation and maintenance status.
By means of an RS 232 interface, all data can be visualized on a PC and the
whole system can be configured. A Centronics interface is available for connec-
tion of a printer.

13
2.1.2.Analog Input Module (AEM)
The transducers are connected through the analog input modules. Each module
accommodates up to any eight transducers of 4-20mA and provides an addi-
tional RS 485 interface per channel. Via this interface, communication can be
established during maintenance between a PC connected to the controller mod-
ule and the respective transducer. Up to eight analog input modules can be con-
nected to the controller module. An address of 1 to 8 is allocated to each module
by rotary switch.

14
2.1.3.LED Module
The status of every channel is indicated by LEDs. (One transducer can be con-
nected to each channel.) Operation of the key buttons for the respective channels
displays additional information on the relevant transducers on the LCD module
and triggers further functions such as alarm suppression, operational test, chan-
nel disconnection and calibration mode. The LED module consists of an LED
panel for 16 channels and one or two PCBs for eight channels each.

16
A basic relay module has eight relays and can be extended by a further eight re-
lays through a pluggable extension relay module.
Redundant triggering of the relays is via two 8-bit microcontrollers. Free param-
eterization of the relays with the aid of the software ConfigPro meets all indi-
vidual requirements:
•AND-to-OR Logic Operation
•Open and Closed Circuit Operation
•Grouping
•Voting
•Time-delay and Slow Release
•Relay Function for Buzzers
•Relay Reproduction
Up to eight relay modules with a total of 128 relays can be integrated in the sys-
tem. The redundant, optodecoupled RS 485 bus enables spatial separation (up to
1km) of the modules and control unit. An address of 1-8 is allocted to each
module via rotary switch.
Open circuit:
The relays are activated as soon as the respective status is recognized, ie the re-
lays pick up.
Closed circuit:
The relays are activated during undisturbed operation, ie the relays have picked
up and will be deactivated in case of alarm, ie the relays will be released.

17
2.1.5.Analog Output Module (AAM)
The employment of up to eight analog output modules with a total of 64 outputs
allows transmission of transducer signals (4-20mA or 0-10V). An address of
1-8 is allocated to each module by rotary switch.

18
2.1.6.LCD Module
The system WinPro® can be equipped with a graphic LCD display (240 x 128
pixels) showing, for example, information on measuring points, all relevant sys-
tem parameters as well as system events and histograms. The LCD module is
provided with an integrated data logger having a storage capacity of up to 32
MB.
2.1.7.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.

ve, distant, n’est pas équipé des 4 LED. Les boutons
sont inactifs.

19
2.1.8.Adapter module (numeric loop)
•This adaptator module is the interface between the controller module
"CMN" (CPU) and the numeric loop.
On this numeric loop, it will be possible to connect directly :
-Up to 16 numeric and addressable transmitters,
-Or 2 analogical input modules
-Or 16 analogical transmitters connected to the numeric loop
thanks to "address boxes".
Warning : the numeric loop manages up to 16 adresses independently of the
mode in use.
A analogical inputs module will take the place of 8 adresses.
•Topology in link of the numeric loop :
-100 % redundant
-in case of breaking off of the loop : instantaneous recapture of the
measurements.
-Automatic stop of a transmitter in case of failure
-Tele-power supply of the transmitters

20
2.2.Description of Redundancy
The redundant structure of the system WinPro® means that the complete safety
functions are provided twice. From conversion of the analog signals into bus
signals to evaluation in the controller module and relay connection, any single
error will not lead to failure of the safety functions. In addition, the two control-
lers of the controller module continuously compare with one another. Thus, not
only single-error-protection is achieved but also maximum availability.
To fulfill maximum safety criteria, the whole safety chain from trans-ducer to
relay must be provided twice. Linking of transducers and relays can be carried
out with the software ConfigPro.
2.3.Description of Control Panel
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 fur-
ther LED modules can increase the number of channels to 64. The LED modules
are identified by letters A to D, the channels are always numbered consecutively
from 1 to 16.
Inputs Channel Identification
from to LED module from to
116 AA1 A16
17 32 BB1 B16
33 48 CC1 C16
49 64 DD1 D16
The inputs can also freely be allocated to the LED modules with the software
ConfigPro.
When using the optional LCD module, the four LEDs for status monitoring are
displayed thereon. The logo module is then no longer necessary.

21
3.Operation of the System WinPro®
The system WinPro® is the control unit of the transducers connected which re-
quires different operating modes described in this chapter. For each mode, the
LEDs for the respective channels provide different information.
3.1.Channel and System Information
Basically, two types of information are available, on the channels and the sys-
tem. The channel information refers to each individual trans-ducer. The LED
module provides seven LEDs for every channel.

And keyboard for 64 detectors

The channels are numbered from 1 to 16.
