MGC2 Analog Gas Controller

1 Application

The PolyGard ® MGC2 Gas Controller is used for monitoring and warning of toxic and combustible gases and vapors in the ambient air. The MGC2 Gas Controller fulfills the requirements according to VDI 2053 (January 04), ÖNORM and NVN 2443 for the stationary monitoring of carbon monoxide (CO), nitrogen dioxide (NO

2

) and combustible gases in underground garages, tunnels, go-cart race courses etc. The MGC2 Gas Controller also fulfills the requirements according to EN 378, VBG 20 and the guidelines “Safety requirements for ammonia refrigeration systems”. The Gas

Controller can be used as well for monitoring lot of other gases.

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 EN55 02). The Gas Controller may only be used in ambient conditions as specified in the Technical Data.

The PolyGard ® Gas Controller MGC2 must not be used in potentially explosive atmospheres.

2 Description

The Gas Controller is a measuring and warning controller for the continuous monitoring of different toxic or combustible gases and vapors as well as freons. The MGC2 is suitable for the connection of up to 24 analog transmitters.

Up to five free programmable alarm thresholds are available for each transmitter. For transmitting the alarms there are up to 30 relays with potential-free, change-over, dry contacts.

Comfortable and easy operation of the Gas Controller is done via the logical menu structure. A number of integrated parameters enables the realization of various requirements in the gas measuring technique. Configuration is menudriven via the user-friendly keypad.

Prior to commissioning please consider the guidelines for wiring and commissioning for hardware.

2.1 Normal Mode

In normal mode, the gas concentrations of the active transmitters are continuously polled and displayed at the LCD display in a scrolling way. The Controller also monitors the communication to all active transmitters and modules.

2.2 Alarm Mode

If the gas concentration reaches the programmed alarm threshold, the alarm is started, the assigned alarm relay activated and the alarm LED (orange for alarm1, red for alarm 2 + n) starts to flash. The alarming sensor number can be read from the menu Alarm Status. When the gas concentration falls below the alarm threshold and hysteresis, the alarm is automatically reset. In latching mode, the alarm has to be reset manually in the menu Relay Status or via a digital input.

2.3 Fault Mode

If the Controller detects an incorrect communication at an active transmitter or module, or if a signal is outside the admissible range (< 3 mA - > 22 mA), the assigned fault relay will trip and cause the Fault LED to flash. The error is displayed in the menu Error Status in clear text.

After removal of the cause, the error message must be acknowledged manually in the menu Error Status.






3 Operating Instruction

The complete configuration, parameterization and service is made via keypad user interface in combination with the display screen. Security is provided via two password levels.

3.3 Code Levels

According to the regulations of all national and international standards for gas warning systems, all inputs and changes are protected by a four-digit numeric code (= password) against unauthorized intervention. All menu windows are visible without entering a code.

The release of a code level is canceled if no button is pushed within 15 minutes.

The code levels are classified in order of priority: Priority 1 has top priority.

Priority 1 : Upper Level (password 9001 – not changeable)

Code level priority 1 is intended for the service technician of the installer to change parameters and setpoints. All settings can be treated with this password.

Priority 2 : Lower Level (password 1234 – not changeable)

Code level priority 2 allows the operator:

- to acknowledge faults

- to manually operate the alarm relays

- to set date and time

- to configure the data logger.

4.1 Fault Management

The integrated fault management records the first 20 faults with date and time stamps in the menu “System Errors”.

Additionally a record of the faults occurs in the “Error memory”, which can only be read and cancelled by the service technician.

An actual fault activates the fault indication relay which is defined in the system parameter “Fault relay” after an internal fault delay time of 2 minutes. The yellow LED (Fault) starts to flash and the fault is displayed in plain text with date and time in the starting menu.

In case of the fault of a connected transmitter the alarms defined in the menu “SP Parameter” are activated in addition.

4.1.1 Acknowledge a Fault

Attention:

Acknowledging of a fault is only possible after having removed the cause!

In order to recognize situations where errors and faults occur sporadically and temporarily, their error states - even after return to normal operations - are displayed until they are manually acknowledged.

This functionality is available from version 9.02

If a transmitter is damaged or completely destroyed, the consequence is that the ventilation works continuously. This functionality can be used until the transmitter is repaired or replaced.

In the Lock Mode the function of the existing transmitter is put out of service, which means there is no alarm or fault message at this sensor point. If at least one transmitter is blocked in its functionality, the collective fault message is activated, the yellow fault LED is flashing and there is a message in the menu System Errors.

In the gas measuring technique, most of the gases are monitored for their increasing concentration. For example oxygen, however, is monitored for its falling concentration. In this menu there is the definition how many of the 5 alarm thresholds monitor a falling concentration.

4.6.4 Measuring Range Definition

The measuring range can be adjusted to the working range of the connected gas transmitter within 10 to 10000.

4.6.5 SP Signal Definition

Gas transmitter using electro-chemical or catalytic beat gas sensors normally produce a linear signal, proportional to the gas concentration.

Semiconductor gas sensors produce a non-linear (exponential) signal due to the measuring function. This signal leads again to a non-linear 4 to 20 mA signal of the gas transmitter.

The Gas Controller GC-05 is prepared for both types of gas transmitters. The classification of signals is defined in this menu.

4.6.6 Threshold/Hysteresis

For each sensor point five alarm thresholds are available for free definition. If the gas concentration is higher than the set alarm threshold, the associated alarm is activated. If the gas concentration falls below the alarm threshold inclusive hysteresis the alarm is again reset. In the mode “Alarm at falling” the corresponding alarm is set in case of falling below the set alarm threshold.

Unused alarm thresholds have to be defined at measuring range end point, in order to avoid false alarms.

4.8.5 Maintenance Concept

A control of the maintenance intervals required by law or by the customer is integrated in the MGC2 system.

At commissioning or after maintenance the date for next maintenance is entered. When this date is reached, the failure signal is activated the next morning at 9 o’clock, and the phone no. of the service technician occurs in the display instead of the measured values. The text message “Maintenance” and the service phone no. can only be reset after having accomplished the maintenance by entering the next maintenance date.

The service phone no. can be entered individually in the next menu.

4.8.6 Average Function

Not used in USA.

The each active sensor point the Gas Controller calculates the arithmetic average value out of 10 measurements got within the time unit defined in the menu „AV-time“. Depending on the definition of the operating mode the alarm is evaluated with the current or the average value. In the average mode, the average value is indicated in the menu “Sensor Values” next to the current value. The control mode (current or average value) for the evaluation of the alarm is defined for each sensor point.

The alarm evaluation of the control mode “Average Value” is overlaid by the current value, when the current value exceeds the alarm threshold defined in the menu “AV-Overlay”. The overlay is delayed by the time factor defined in this menu. The average overlay function is only active for the gas type CO.

When operating the DI with these settings, all non-active error messages are deleted and moved to the service technicians menu.

Note:

This function is not suitable for all applications. Especially in connection with pellistors and higher gas concentrations, it is not allowed because the absence of gas has to be checked manually on site.

In such cases, this input should only be able to be actuated by a key switch.

4.8.12 Power On Time

Gas sensors need a running-in period, until the chemical process of the sensor reaches stable conditions. During this running-in period the current signal can lead to an unwanted releasing of a pseudo alarm. Therefore the Power ON time is started at the Gas Controller after switching on of the power supply. While this time is running out, the Gas

Controller does not activate alarms. The power on status occurs on the first line of the starting menu.

4.8.13 Registration of Expansions Modules

The MGC2 system can manage up to five EP-05 expansion modules, each consisting of 5 alarm relays, 4 analog inputs and 2 analog outputs. The module’s addresses, 1 to 5, are assigned via the address selector on its printed circuit board. Connected EP-05 modules are registered in this menu with the desired function (only alarm relay or alarm relay + analog input). See table.

The Controller constantly checks registered EP-05 modules and will shows a fault signal in the event of a communication error.

Note:

EP Module 0 is the built-in GC-05 Controller Module and should not to be confused with other EP-05 Expansion

Modules . This unit is always active and cannot be disabled.

Active analog inputs at an EP module occupy the four SP addresses; therefore they aren’t available any longer for the bus transmitters.






The table shows the assignment of the relay numbers and of the analog in/outputs to the EP module addresses.

4.8.14 Error Indicator System Bus

All data packets received by the GC-05 are checked for completeness and compatibility. Faulty data packets are recorded by the error counter. Max. 1-2 faulty data packets are admissible a day.

A higher error rate mostly comes from incorrect wiring of the field bus line.

4.8.15 Analog Output

The Gas Controller Module as well as the EP-05 Modules 1 to 5 have two analog outputs (AO) with 4 to 20 mA signal each. The signal of one or more sensor points can be assigned to each of the analog outputs. The assignment is effected in the menu “SP Parameter” for each SP. The sensor point sends the signal, which is defined in the menu

“C/A Mode”.

Out of the signals of all assigned sensor points the Gas Controller determines the minimum, the maximum or the average value and displays it at the analog output. The definition, which value is transmitted, is effected in the menu “Analog Output X”.

The analog output can be calibrated at 4 and at 20 mA. Therefore an ampere meter (measuring range 25 mA) can be attached to the AO and the respective factor has to be changed until the analog output corresponds to 4 and/or 20 mA.

During calibration evaluation of the sensor point signals is not possible. This calibration is effected by the factory. The factors should not be changed.

4.8.16 Relay Multiplication

This function is available from version 9.02.

With the relay multiplication table, it is possible in the MGC2 system, to assign an alarm to multiple relays.

There is a maximum of 20 entries for In-relays and Out-relays. So it is possible to expand one relay to 20 others or to double max. 15 relays.

In the column IN, the relay assigned to an alarm in the menu SP Parameter is set.

In the column OUT, the additionally required relay is entered.

Note:

Manual intervention on IN or Out relays in the menu Relay Status or via external DI will only affect the single relay!

Example 1:

3 relay contacts are needed with the same effect of relay 3.

(see assignment of the relays in chapter SP Parameter)

Entry: 1: IN 3 Out 7

Entry: 2: IN 3 Out 8

If relay 3 is activated via an alarm, relays 3, 7 and 8 switch at the same time.

Example 2:

2 relay contacts each are needed from 3 relays (for ex. 7, 8, 9).

Entry: 1: IN 7 Out 12 (Relay 12 switches at the same time as relay 7)



This means that relay 7 switches with 12; 8 with 13; 9 with 14.

The two examples can be mixed up, too.






5 Programming Operation

Before beginning startup 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 startup unless arrangements have been made with the factory for programming. All other parameters are to be examined and adapted to the local conditions.

6 Notes & General Information

It is important to read this User Manual carefully in order to understand the information and instructions. The

PolyGard ® MGC2 gas monitoring, control and alarm system may only be used for applications in accordance to the intended use. The appropriate operating and maintenance instructions and recommendations must be followed.

Due to permanent product developments, MSR-Electronic GmbH and IN TEC Controls reserves the right to change specifications without notice. The information contained herein is based on data considered to be accurate. However, no guarantee or warranty is expressed or implied concerning the accuracy of these data.

6.1 Intended Product Application

The PolyGard ® MGC2 is designed and manufactured for controlling, for saving energy and keeping OSHA air quality in commercial buildings and manufacturing plants.

6.2 Installer’s Responsibilities

It is the installer’s responsibility to ensure that all PolyGard ® MGC2 are installed in compliance with all national and local regulations and OSHA requirements. All installation shall be executed only by technicians 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 follow strictly all instructions as provided in the User Manual.

6.3 Maintenance

All monitoring and control systems such as the PolyGard ® MGC2 should be periodically recommissioned.

Recommissioning includes verifying that all field devices such as gas transmitters and fan controls are preforming to their original specifications, that the system’s sequence of operation is fully functional, and that minimum ventilation rates as required by local codes are being met. Common problems identified during recommissioning include sensors that are out of calibration and fans that have been left in “hand” mode (manually off or manually on) either at the motor control panel or in the gas controller’s configuration.

Recommissioning typically begins with verifying the measurement accuracy of a select number of gas transmitters by presenting them with calibration gas and viewing the transmitter’s digital response. If all of the tested transmitters are within their original specified accuracy, it is generally accepted that the remainder of the transmitters are also “in calibration”. If any of the tested transmitters are “out of calibration”, those transmitters should be calibrated and the rest of the transmitters in the system should be tested and calibrated as required.

The system’s sequence of operation is tested by presenting test gas to one or more transmitters in each fan control zone and verifying that the fan is activated and de-activated according to the desired control parameters (start/stop delay and minimum on/off time) – “bump testing”. If the system incorporates variable speed fans, the technician must be able to verify setup parameters in the variable speed drive as well as the MGC2.

The re-calibration interval for a gas transmitter is highly dependent on the amount of the target gas that the transmitter is exposed to over time. Refer to the transmitter manufacturer’s technical documentation for recommendations.
