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.

4.1.2 Error Memory
The menu “Error Memory” in the main menu “System Error” can only be opened via the code level priority 1.
In the error memory, the 20 first faults already acknowledged in the menu “System Error” are listed for the service
technician.
The error memory is captive, even in case of power failure.
This memory should always be emptied during maintenance.
The deletion of each individual message is effected in the same way as the reset of a fault.
