WHICH FUNCTIONS MAY BE PROGRAMMED?
It is possible to program 5 functions for each
of the input channels 1 to 8.
Furthermore, programming of 4 common functions is possible.
The individual functions are as follows:
1) Registration of alarm on open or closed signal contact
- i.e. selection between N/C or N/O.
2) Activation of output(s) A and/or B on an alarm condition
- "OUTPUT A", "OUTPUT B"
3) Inhibit of incoming alarms
- "INHIBIT"
4) Detection and indication of cable failure
- "CABLE FAILURE"
5) Time delayed registration of an alarm condition.
The time delay "DELAY OF ALARM" can be set within the range 0..40 secs at intervals of 1
sec.
The common functions are as follows:
1) Activation/deactivation of relay for output A on an alarm condition
- (N/O, N/C)
2) Time limited activation/deactivation of output A.
The time limit can be set within the range 1..10 secs at intervals of 1 sec.
3) Activation/deactivation of relay for output B on an alarm condition
- (N/O, N/C)
4) Time limited activation/deactivation of output B.
The time limit can be set within the range 1..10 secs at intervals of 1 sec.
5) Delayed cancellation of inhibit function.
The delay can be set within the range 0..40 secs at intervals of 1 sec.
NOTE: When common functions are programmed, no channel is selected, only
functions. Individual functions may be programmed before common
functions or vice versa. The description of the programming of common
functions starts on page 15.
