4.7.3
Alarm module
Function
The alarm module triggers fault messages and alarms via three binary outputs. The
message function is based on the change in the signal status:
● If the signal status is "HIGH", there is no alarm message and the binary inputs are
conductive.
● If the signal status is "LOW", the module reports an alarm by shutting down binary
outputs using a high-resistance.
● Operational faults are signaled at a high-resistance output. Set the following parameters
to activate and configure the output of alarms and fault messages:
– "AFCT" - Alarm function
– "A1" - Response threshold, alarm 1
– "A2" - Response threshold, alarm 2
– "FCT" - Function fault message output
– "TIM" - Monitoring time
– "LIM" - Response threshold
Apart from binary outputs, the alarm module has a binary input BIN2. Depending on the
selected parameters, it is used to block the actuator or to move it to its end position.
Configure the suitable settings on parameter "BIN2".
