CIAT FLOWAY ACCESS User Manual

8 - FAULTS
When the PLC detects an issue, it triggers a fault.
8.1 - Fault type
Faults may either be "maintenance" or "danger" type faults.
"Maintenance" faults are information provided to the user and signal that the unit is not operating correctly, but that this does not
have any immediate consequences (a fouled lter, for example). These may be cleared once the issue has been resolved.
"Danger" faults are issues which prevent the unit from operating; the unit will shut down immediately (or after the fan delay). The
issue must be resolved before the unit can be restarted. The faults may be cleared once the unit has been shut down and the fault
has disappeared.
"Maintenance" faults may be congured as "danger" faults using parameters P602 to P651. Conversely, for safety reasons, it is
not possible to congure "danger" faults as "maintenance" faults.
8.2 - Fault relays
The PLC contains a faults summary relay. This relay is a 250Vac / 6A type relay. It is triggered when at least one "maintenance"
or "danger" fault is present. If it is an EC motor warning from one of the fans, its triggering depends on parameter P292.
Its action direction is congurable (P882).
8.3 - Fault memory
The PLC stores the last 100 faults and the date and time that each of these faults occurred. This is menu
4 "fault memory". This memory cannot be cleared.
