4.5.3 Alarm modules 6DR4004-6A and -8A
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 for 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, this binary input is used to block the actuator or to move it to its end
position. Configure the suitable settings on parameter "BIN2".
