Alarms
5.1 Alarm Response
Function 60 can be used to switch off the logbook and also to delete the messages stored in
it.
The output of messages can become inconvenient particularly during test runs. Therefore
this function can be switched off using function 88. It is not recommended to use this facility
during normal operation.
Relays
If the relay outputs of the analyzer have been configured accordingly, it is possible to output
a signal when an alarm occurs.
Stored Value
The analog output can be set to the last measured value or to 3 mA when an alarm occurs
(function 77). This response signal is only possible for "Fault alarm", "Transmission alarm",
"Transmission pending" and "Function control alarm".
