If the alarm condition is met, the programmable alarm will be set and the
associated digital output will be activated when the alarm is present for a preset
time.
The time during which the alarm condition has to be present has a minimal value
of 180 s and can be increased if desired. In order to increase the time during
which the alarm has to be present before the digital output is triggered, go to
[/Welcome/Settings/Customer set./Alarms/Prog. Alarms/Alarm delay].
Note that the delay programmed here is also applied to the filter alarm contact.
The digital output will be deactivated if the alarm has disappeared for a preset
time, which is by default 1 s. In order to change the alarm reset delay, go to
[/Welcome/Settings/Customer set./Alarms/Prog. Alarms/Alarm rst. Del.].
When configuring the programmable alarm as 'Any' it will trigger the digital output
if any of the fault conditions presented in
The programmable alarms can be deactivated by setting them to 'Disabled'.
Remarks: Difference between the alarm contact and the digital output used as
alarm contact:
The alarm contact is triggered by any fault that makes the system trip. These
faults include the conditions mentioned in
internal filter faults that may occur. An exhaustive list of faults that may make the
filter trip and thus trigger the alarm contact is given in
Use the digital outputs as alarm contact if the aim is to find the exact cause of the
filter trip without having to analyze the event-logging window.
· Set up of the programmable warnings
For setting up the programmable warnings go to [/Welcome/Settings/Customer
set./Warnings/Prog. Warnings]
For full redundancy with multi-master filters, these functions need to be set up in
each master unit of the filter system and the functions should be cabled
accordingly.
Three programmable warnings can be defined. Similar to the programmable
alarms, they can be associated with a digital output.
warning conditions that can be associated with each programmable warning.
Unlike alarms that cause a filter trip, warnings only activate the digital output
contact.
