MGC2 – UserManual Specifications subject to change without notice. | USA 160811 | Page 8 of 34 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.

MGC2 – UserManual Specifications subject to change without notice. | USA 160811 | Page 31 of 34 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.
