3.6.3 Measuring range

The measuring range can be defined within 10 to 10000 freely. The measuring range in the table gastype are non obligation recommendations.

The measuring range must agree with the signal (4 to 20 mA) attached gas transmitters. (4 mA = Display 0 (ppm), 20 mA = Display Measuring range max. point) 3.6.4 MP Signal

Gas transmitter with electro-chemical - or catalytic beat gas sensors spends in rule a linear, for gas concentration proportional 4 to 20 mA signal.

Semiconductors gas sensors spend a not linear (exponential) signal. This signal leads to a non linear 4 to 20 mA signal of the gas transmitter.

The Gas Controller MGC-02 is for both type of gas transmitters prepared. The classification of signals is defined in this menu.


MP 01 Measuring Point Selection MP No.

Linear MP Signal linear linear = Transmitter with linear Output signal Non linear = Transmitter with non linear Output signal (Only Series AT from MSR-E)

3.6.5 Threshold / Hysteresis

For each measuring point five alarm thresholds for the free definition are available. If the gas concentration greater the adjusted alarm threshold, the associated alarm is set. If the gas concentration falls below the alarm threshold inclusive hysteresis the alarm is again put back.

Not Necessary alarm thresholds to be defined on measuring range end point, in order to avoid false alarms. With O2 measurement ocurs an alarm release with falling measuring signal!

3.7.3 Maintenance Concept

In the MGC-02 system is a monitoring of the maintenance intervals, given by the Regulations or Customer, integrated.

With start-up and/or after maintenance the date for next due maintenance is entered. With reaching this date on the next morning at 9 o'clock the failure signal is activated and in the display the phone No. of the service technician is overlay. The failure signal (maintenance) can be acknowledged by the operator. The maintenance message (Service Phone No.) is put back after accomplished maintenance with input next maintenance date.

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

3.7.4 Average Function

The Gas Controller calculate for each active measuring point the arithmetic average value from 10 measurements within time unit defined in the menu AV-time. This average value is indicated in the menu Measuring Values near the current value. At each Measuring Point the control mode of current value or average value for the alarm evaluation is defined.

The alarm evaluation of the control mode average value is overlaid by the current value, if this exceeds alarm threshold defined in the menu AV-Overlay.The overlay is delay with the time factor in this menu.

3.7.7 Analog Output

The Gas Contoller has two analog outputs (AO) with 4 to 20 mA signal. Each of the analog output can be assigned the signal of one or more measuring points. The assignment occurs in the menu MP Parameter for each MP. The measuring point sends the signal, which is defined in the menu C/A Mode.

The Gas Controller determined from the signal of all assigned measuring points the minimum, the maximum or the average value and spends in at analog output. The definition, which value is spent effected in the menu Analog Output X.

The analog output can be calibrated with 4 and with 20 mA. In addition at the AO an ampere meter (measuring range 25 mA) is attached and the respective factor changed to the analog output 4 and/or 20 mA corresponds. During the calibration ocurrs no evaluation of the measuring point signals. This calibration occurs factory-set. The factors should not be changed.

Gas sensors need a break-in period, until the chemical process of the sensor reaches a stable condition. During this break-in period the current signal can lead to unwanted releasing of a pseudo alarm. Therefore at the Gas Controller is started after switching on of the power supply the Power On Time. While this time runs off, the Gas Controller does not spend alarms. The power on status is overlay in the starting menu.


30 s Power On Time 30 s XX = Define the Power On Time (sec.) 3.7.10 Registration of expansions modules

The gas Controller can manage, up to five expansions modules (EP-02). Each EP-02 has four analog inputs and five alarm relay. Each attached EP-02 is announced in this menu. The Controller monitors the communication to the announced EP-02 modules and spends at a communication error a fault signal. For the recognition of the position of the EP-02 modules a module address is assigned to each module with the address selector. See table.

The table shows the assignment of the MP and relay numbers to the individual modules.

The Alarms also connected directly at the module with the carge clamps. At the clamps of the alarm relays in each case 2 contacts are present.

The alarms are available as DPDT, potenialfree contacts. If necessary the power supply volltage is available at the clamps L1.

The exact position of the clamps for the transmitters and alarm relays is to be inferred the following connection diagram.

The connection diagram contains those maximally possible number of expansion modules. Depending upon Gas Controller type are however only individual modules equipped.
