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.

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.

3.6.3 Measuring range
The measuring range can be defined from 10 to 10000. The measuring ranges in the above table are typical and
only recommendations. For actual ranges see the sensor manufacturing specifications.
The measuring range must agree with the signal (4 to 20 mA) for active transmitters.
(4 mA = Display=0, 20 mA = Display Measuring range = max. point)
3.6.4 SP Signal
Gas transmitter with electro-chemical or catalytic bead sensors are linear for gas concentration proportional to the
4 to 20 mA signal.
Semiconductor gas sensors that are not linear and have a (exponential) signal. This signal is non-linear 4 to 20
mA signal from the gas transmitter.
The Controller MGC2 has the capability to monitor both types of gas transmitters, and other linear 4-20 mA
sensors. The type of signal is defined in this menu.

3.6.5 Stage/Setpoint / Hysteresis
Each sensor point can have five stages with set point values. If the measured level is greater than the defined
stage/set point, the associated stage is set. If the level falls below the stage/setpoint plus the hysteresis then the
stage returns to original condition.
It is recommended that the unused stages be set to max of sensor range to avoid the alarm light from false
reporting.
For O2 measurement on depletion consider when defining stage setpoints that stages will be set on a falling
measuring signal!

3.7.7 Analog Output
The Controller has two analog outputs (AO) with 4 to 20 mA signal per control module. Each of the ten analog
outputs can be assigned the signal of one or more sensor points. The assignment occurs in the menu “SP
Setup” for each SP. The sensor point sends the signal that is defined in the menu “C/A Mode”.
The Controller determines from the signal of all assigned sensor points the minimum, the maximum or the average
value and sends this value to the analog output. The determination of which value is sent is defined in this menu
“Analog Output X”. The analog output can be calibrated for 4 and 20 mA using an ampere meter attached (with
measuring range 25 mA) then respective AO factor can be changed to adjust the analog output 4 and/or 20 mA
During AO calibration no evaluation is made of the sensor point signals. This calibration is factory-set. The factors
should only be changed if you have an accurate amp meter.

3.7.9 Power On Time
Sensors need a warm up period until the chemical process of the sensor reaches a stable condition. During this
warm up period the current signal can cause unwanted false alarms. Therefore, the Controller starts reporting
alarms after the Power ON Time delay once power is applied. While this time runs off, the Controller does not
report alarms. The Power On status is displayed.

The Gas Controller can manage, up to five expansions modules (EP-02). Each EP-02 has four analog inputs and
five alarm relays and two analog outputs. Each attached EP-02 is announced in this menu. The Controller checks
the communication to the registered EP-02 modules and shows a fault signal in case of a communication error. To
recognize the position of the EP-02 modules a module address is assigned to each module by the address
selector. See table.
The table shows the assignment of the MP and relay numbers to the individual modules.

4 Mounting / Electrical Connection
The Controller is installed through the 4 marked mounting holes at the back of the housing. These mounting holes
are accessible after opening the housing. See Fig. 01
The mounting holes should be covered with the enclosed caps after installation.
Please consider the following when selecting the mounting place:
Avoid locations where water, oil etc. may influence proper operation and where mechanical damage might
be possible.
Install cables only from the Topside.
On the left side keep at least 150 mm distance to open the transparent door.
Consider any unusual condition or requirements of the Customer.

User Manual - MGC2-20
5 Start-up Operation
5.1 Start-up
Before beginning start-up the wiring of the Controller including all field devices must be completely terminated!
After switching the power supply “ON” and the end of the Power On Time, then the Controller is ready for use.
The electrochemical sensor needs a warm up time of 1 hour to reach its highest accuracy.
The Controller is delivered with standard parameters and stages/set points. The assignment of the relays to the
individual stages can occur at start-up unless arrangements have been made with the factory for programming. All
other parameters are to be examined and adapted to the local conditions.

8.1 Intended product application
8.2 Installers’ responsibilities
®
MGC2 monitoring, control and alarm system must be used within product specification capabilities. The
The PolyGard® MGC2 are designed and manufactured for control applications for energy savings and OSHA
air quality compliance in commercial buildings and manufacturing plants (i.e., detection and automatic exhaust
fan control for automotive maintenance facilities, enclosed parking garages, engine repair shops, warehouses
with forklifts, fire stations, tunnels, etc.).
It is the installer’s responsibility to ensure that all PolyGard® MGC2 are installed in compliance with all national
and local codes and OSHA requirements. Installation should be implemented only by individuals familiar with
proper installation techniques and with codes, standards and proper safety procedures for control installations
and the latest edition of the National Electrical Code (ANSI/NFPA70). It is also essential to strictly follow all
instructions as provided in the user manual.
Page 36
8.3 Maintenance
It is recommended that the PolyGard® MGC2 performance check is done on a routine schedule. Any
performance deviations may be serviced based on needed requirements. Part replacement may be
implemented in the field by a qualified individual and with the appropriate tools.
8.4 Limited warranty
MSR-Electronic-GmbH and INTEC Controls warrants the PolyGard® MGC2 for a period of two years from the
date of shipment against defects in material or workmanship. Should any evidence of defects in material or
workmanship occur during the warranty period, INTEC Controls will repair or replace the product at their own
discretion, without charge.
Thiswarrantydoesnotapplytounitsthathavebeenaltered,hadattemptedrepair,orbeensubjecttoabuse,
accidental or otherwise. The above warranty is in lieu of all other express warranties, obligations or liabilities.
This warranty applies only to the PolyGard
liable for any incidental or consequential damages arising out of or related to the use of the PolyGard
If the PolyGard
