Unit Level Prevent Alarms
Prevent Alarms are also indicated by a steady alarm icon at the
side of the display. The unit will be temporarily shut down if a
Prevent Alarm is active. The unit will remain shut down for a
timed restart interval or until the fault conditions are corrected
and then restart. If the unit is in a temporary shutdown, Alarm
Code 84 Restart Null will be present along with the associated
Prevent Alarm. In most cases the unit will restart with reduced
performance to determine if continued operation is possible. If
the alarm does not reoccur with reduced performance then the
unit will then return to full performance. If the unit is operating
with reduced performance Alarm Code 85 Forced Unit
Operation may also be present under some conditions. In
general, if the alarm condition re-occurs a defined number of
times then the alarm is set as a Shutdown Alarm and no further
restarts are possible. The TemperatureWatch screen is disabled
if a Unit Level Prevent Alarm is active.
NOTE: If the Restart After Shutdown feature in the Guarded
Access Menu is set for CONTINUOUS, then an unlimited
number of restart attempts are allowed.
