Description
If fail-safe mode is not selected, alarm contact output
relays are normally de-energized and will be energized
when an alarm assigned to the contact occurs.
Alternatively, if fail-safe mode is selected, the alarm
contact output relays are normally energized and will be
de-energized when an alarm assigned to the contact
occurs.
If reflash is not selected, alarm contact output relays will
energize/de-energize based on any alarm(s) assigned to
the contact changing state. Alternatively, if reflash is
selected, alarm contact output relays will momentarily
de-energize (approximately 100 msec.), then re-energize
each time any alarm assigned to the contact changes
state.
Description
A "fill" percent is set to trigger an alarm when the
media reaches a set level.
Any fault in the unit triggers this alarm (future
option). The Unit Fault selection is not available in
this release. Unit fault conditions may be addressed
and annunciated by a number of enhanced discrete
recorder setup options. Consult the factory for
details related to these options.
Can be linked to point alarms so that any point that
goes into alarm also triggers the common alarm.
Additional options for point alarms are:
Open on Alarm Clear: Common alarm clears
when the point alarm clears.
Open on Acknowledge: Common alarm clears
when the point alarm is acknowledged.
