21 FAULT & RUN INDICATION
With the S-ASX 30-50 heat pump controller, there is no specific terminal number for either a fault or run indication.
However
as per chapter 14.6 “Input and Output,” there are QX outputs available as a spare which can be addressed
for fault & run indication. The outputs used will need addressing onsite to the following:

22 S-ASX Heat Pump Fault / Alarm
22.1
Fault / Alarm Activation & Reset
The controller can perform a complete diagnosis of the unit detecting all the operating faults and notifying different
alarms. The activation of an alarm implies:
-
Involved consumers locked.
-
Alarm icon shown on the display.
-
Event recorded in the alarm history.
Errors that can damage the unit or the plant require a
manual reset
that implies that the operator must reset manually
the controller. It is advisable to verify accurately the cause that originated the error and to make sure that the problem
has been solved before restarting the unit. In any case the unit will restart only if the cause of the error has disappeared.
The less critical errors have an
automatic reset
. As soon as the minimum compressor switch off time has elapsed the
controller tries to reset the error. If the cause that originated the error has disappeared, the unit starts working again and
the error icon is no more shown on the display. Some of these errors become manual reset errors if the number of
events in an hour exceeds a fixed threshold.
22.2
Fault / Alarm History
The controller allows to save the last 10 alarms occurred during the unit operation. For each event the following details
are recorded:
-
Fault / Alarm code.
-
Date of fault / alarm.
-
Time of fault.
When the number of saved events is higher than 10 the following events are saved deleting the oldest errors.
NOTE: To show the details about the active error and manual reset, please refer to paragraph "Evaluate and
operate info pages (errors)".
It is possible to reset the active errors also through the parameter 6711 that enables the RESET function. In that case
the scheduled delays at the unit switch on are ignored avoiding undesired waiting times during commissioning or fault
tracing. This function should NOT be used in normal operation.
