Alarms and Alerts —
There are a variety of different
alerts and alarms in the system.
T — Alert: Part of the unit is down, but the unit is still par-
tially able to provide cooling or heating.
A — Alarm: The unit is down and is unable to provide cool-
ing or heating.
All alarms are displayed with a code of AXXX or TXXX
where XXX is the alarm/alert number. All alerts start with “T”
and all alarms start with “A”. The response of the control sys-
tem to various alerts and alarms depends on the seriousness of
the particular alert or alarm. In the mildest case, an alert does
not affect the operation of the unit in any manner.
In addition, the compressors have several diagnostics
monitoring the safety of the system which may cause a
number of attempts to be re-tried before locking out the system
from operation. This feature reduces the likelihood of false
alarms causing a properly working system to be shutdown in-
correctly.
For the compressor and circuit diagnostics, some of these
alerts/alarms will not broadcast an initial failure to the CCN
network until all attempts to recover have occurred and failed.
These alerts will be accessible in the alarm history of the
control (Alarms
→
HIST).
All the alarms and alerts are summarized in Table 86.
