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.
