INPUT CONFIGURATION
The alarm inputs are configured as zero potential relay contacts, individually programmable via the
menu to be normally open (NO) or normally closed (N/C). The factory default is N/O for all inputs.
ALARM LATCH
There are three ways of alarm latching:
" Latched until the operator cancels it,
" Latched for a pre-set time (timed out), or
" Not latched (Transparent)
Alarm latching is controlled by a single setting (global) .
Latched alarms:
Alarms are latched as they become active. An alarm will stay active until the operator acknowledges
it. There is no time out period. When the operator acknowledges the alarm, it will be cleared
whether the alarm input is still active or not. Alarms that have been acknowledged by the operator
will not be reactivated unless the alarm input has ceased and then restarts.
Timed out alarms:
Timed out alarms are latched for a pre-set time out period from the start of the alarm becoming
active. After expiration of the time out period, the alarm is automatically cleared unless the alarm
input is still active. The time out period is programmable in the menu by the programmer.
If an alarm input is still active after the time out, the alarm will stay active while the input is active, and
then clear immediately that the alarm is inactive. Alarms that cease and restart before the time out is
complete, will restart the time out period.
Timed out alarms can be cleared by the operator at any time. Like latched alarms, if the operator
cancels the alarm, it will be cleared whether the alarm input is still active or not.
cleared by the operator before their inputs have ceased, will not be reactivated until the alarm input
ceases and restarts.
Transparent alarms (Not latched):
Alarms are active only while the alarm input is active. As soon as the alarm-input ceases, the alarm
will be automatically cleared.
NOTE: The operator cannot clear A Transparent alarm.
