Alarms
If the watchdog relay operates, first check that the relay is energised from the auxiliary
supply. If it is, then try to determine the cause of the problem by examining the alarm
flags
towards
This will not be possible if the display is not responding to key presses.
Having attempted to determine the cause of the alarm it may be possible to return the
relay to an operable state by resetting it. To do this, remove the auxiliary power supply for
approximately 10 seconds, possibly by withdrawing the module from its case.
Then re-establish the supplies and the relay should in most cases return to an operating
state.
Recheck the alarm status if the alarm led is still indicating an alarm state.
The following notes will give further guidance.
9.8.3.1
Watchdog alarm
The watchdog relay will pick up when the relay is operational to indicate a healthy state,
with its "make" contact closed. When an alarm condition that requires some action to be
taken is detected, the watchdog relay resets and its "break" contact will close to give an
alarm.
Note:
There is no shorting contact across the case terminals connected to the "break" contact
of the watchdog relay. Therefore, the indication for a failed/healthy relay will be cancelled
when the relay is removed from its case.
If the relay is still functioning, the actual problem causing the alarm can be found from the
alarm records in the SYSTEM DATA column of the menu (see Chapter 3, Chapter 3.3.5).
9.8.3.2
Unconfigured or uncalibrated alarm
For a CONFIGURATION alarm the control software is stopped and no longer performing
its intended function. For an UNCALIBRATED alarm the control software will still be
operational but there will be an error in its calibration that will require attention.
It may be left running provided the error does not cause any grading problems.
To return the relay to a serviceable state the initial factory configuration will have to be
reloaded and the relay re-calibrated. It is recommended that the work be carried out at
the factory, or entrusted to a recognised service centre.

Setting error alarm

control settings are stored, has been corrupted. The current settings should be checked
