1 Intended Use
The PolyGard2 MGC2 is designed for detection and warning detection of toxic, combustible or dangerous
atmosphere in many commercial and industrial applications.
The intended sites are all areas being directly connected to the public low voltage supply, e.g. residential,
commercial and industrial ranges as well as small enterprises (according to EN50 082).
The PolyGard2 Multi Gas Controller MGC2 must not be used in potentially explosive atmospheres. The
sensor must only be employed in areas within the environmental conditions specified in the Technical Data.
2 Functional Description
2.1 General
The Multi-Gas-Controller is designed for the connection of max. three analog sensors with 4-20 mA signal and
eight Honeywell sensors.
The controller monitors the measured values and activates the alarm relays if the set local alarm thresholds for
pre-alarm and main alert have been exceeded or if there are the alarm messages coming from the eight digital
sensors via RS-485 communication.
The SIL 2 compliant self-monitoring function in the MGC2 activates the fault message in case of an internal
error as well as in case of a fault at the 4-20 mA input / output current signals or if there is a communication
error to the digital sensors.
Other options such as three-color status LED, warning buzzer, digital input for acknowledgment or test function
ensure proper adaptation to the wide range of applications in gas detection technology.

4 Electrical Connection
Assembly work must only be carried out under gas-free conditions!
Consider static electricity instructions (ESD)!
4.1 Wiring
• The technical requirements and regulations for wiring, electrical safety, as well as project specific and
environmental and local conditions etc. must be observed when mounting.
• We recommend the following cable types1:
Europe USA / Canada
Power supply 230 V NYM-J 3 x 1.5 mm
2
14 AWG / 300 V
Alarm message 230 V (also possible together with power supply) NYM-J X x 1.5 mm
2
14 AWG / 300 V
Signal message, bus connection, warning devices 24 V J-Y(St)Y 2x2 x 0.8 mm2 min. 300 V
Possibly connected external analog transmitters J-Y(St)Y 2x2 x 0.8 mm
2
min. 300 V
1
The recommendation does not consider local conditions such as fire protection etc.
• Use copper conductors only for the terminal is only for connection to copper wire.
• Avoid any influence of external interferences by using shielded cables for the bus line, but do not
connect the shield.
• Remove the cable isolation as short as possible. It is important to ensure that bare wires, e.g. wire
shields do not come into contact with the mounted PCB (risk of short-circuit).
• Low voltage wire and mains connected wire must be fixed separately by cable ties or similar, to secure
against looseness.
• Analog sensors are connected directly to the spring type terminals of the module. The correct polarity
must be observed.
• The alarm signals are available as voltage-free change-over contacts. If required, the voltage supply is
available at the terminal L.
The exact position of the terminals for the sensors and alarm relays is shown in the connection diagrams.

8.1 Fault Management
A pending fault activates the yellow LED (Fault).
The integrated fault management records the first 50 occurred faults with time
stamps in the menu “System Errors”. The timestamp shows the days, hours and
minutes that have elapsed since the fault has occurred.
Additionally, a record of the faults occurs in the “Error memory”, which can only be read and deleted by the
service technician (code level 1 (3)).
8.1.1 Error Memory
The menu “Error Memory” in the main menu “System Errors” can only be opened via the code level priority 1.
In the error memory, the first 50 faults that have occurred and have already been acknowledged in the menu
“Error Status” are listed for the service technician in a power failure safe way.
Attention:
This memory should always be read during maintenance, relevant faults should be tracked and entered
in the service logbook, and finally the memory should be emptied.
8.1.2 System Messages and System Errors
The warning device includes a diagnostic module for the continuous monitoring of the relevant functions and
parameters as well as a processor-independent watchdog. These features set the device into the safe mode
"Fault" in case of an internal or external error. The following table shows all possible errors, possible causes,
the related troubleshooting and the resulting device status.
Once the cause has been eliminated, the warning device restarts with the diagnostic mode on its own. It isn’t
necessary to acknowledge the error message. In the event of an error, the error is output as plain text in the
version with display instead of the measured value and in the Error status menu. In case of two or more errors,
the value is output with a cumulative, bit-coded error code.
