User Manual - MGC2-20
Multi Point Controller MGC2
1 Description
The PolyGard® Multi Point Controller MGC2 is used for the monitoring and warning of sensor points exceeding
their stage setpoints. External Transmitters can monitor and warn of toxic, combustible and refrigerant gases as
well as temperature and humidity. The Controller MGC2 can measure up to twenty analog 4 to 20 mA (Gas)
Transmitters.. Each Sensor Point (SP) can have five stage thresholds. Each stage threshold can be assigned to
anyone of the relays (R1…R20). The Controller can interface via ten 4 to 20 mA outputs to any compatible
electronic analog control, DDC/PLC control or automation system.
The adjustable parameters and staged thresholds make this system very flexible for sensor measuring and
control.
The configuration of parameter settings and operation is easy to do without any programming knowledge.
PolyGard
®
Multi Point Controller MGC2 must not be used in areas requiring explosion proof equipment.

3.1 Malfunction management
Malfunction management records the last 15 malfunctions with date and time stamps. In addition, “System Errors”
are recorded in “Error Memory” when the malfunction occurs. This history can be selected and cleared only by the
service technician level 2 password.
A malfunction will display a text message in the Starting Menu. When a failure occurs the relay defined in the
system setup as “Failure relay” is activated. The red LED in the front of the Controller flashes.
During the malfunction of a sensor point (SP) stages that are assigned for sensor failure are activated. Relays that
are assigned to these stages perform as if the stage has been exceeded. These assignments are programmed in
the menu “SP Setup”.

Resetting a malfunction is only possible if the problem is corrected.

3.3.1 Manual operation of the relays
The manual operation of the relays can be accomplished in the menu “Relay Status”. If a relay is in the Manual ON
or Manual OFF status, the yellow LED at the Controller is on continuously.
The external operation of a relay by an assigned digital input has priority before the manual operation or the Stage
set point of a sensor point being exceeded.
Manually operated relays can be reset by selecting the “Automatic” mode.
The reset of Latching relays also is a function in this menu.
