Programmable delay on alarms
Possibility to set programmable delay on alarms configured for binary input 6 and 7 has been added. If
set, it blocks alarms of the respective binary input for the whole time the delay is active. If the reason
for the alarm persists after the delay time expired, the alarm is activated. If not, the alarm does not
appear. This feature allows the user to perform “filtering” of alarms within a specified period of time.
The delay length can be set via the following setpoints:
BI6 Delay
[s]
Delay for alarm on binary input nr. 6
Step:
0.1 s
Range:
0
– 360.0 s
BI7 Delay
[s]
Delay for alarm on binary input nr. 7
Step:
0.1 s
Range:
0
– 360.0 s
