Figure 84. Alarm for Zone 2
Unit Level Prevent Alarm
Unit Level 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, 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 reoccurs a defined number of times, 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.
N No otte e:: If the Restart After Shutdown feature in the Guarded Access Menu is
set for CONTINUOUS, an unlimited number of restart attempts are
allowed.
Zone Level Prevent Alarm
A Zone Level Prevent Alarm will force the affected zone into a temporary
shutdown, but allow the unit to continue to run as required by the host unit
or other zones. A small alarm icon will appear next to the affected zone. If
zone Prevent Alarms occur in all zones, the unit will be forced into a unit
level Prevent Shutdown. The TemperatureWatch screen is disabled if a Zone
Level Prevent Alarm is active.
