DIAGNOSTIC
The following table shows the possible failures and their signalling via alarms (Mains Failure,
Urgent Failure, Non-urgent Failure and End of Autonomy):
Active Alarm
Cause of Failure
LED signalling
Self-
recoverable
Network Failure
•
Input voltage out of range.
Flashes
"Network Input Failure"
Yes
Urgent Failure
•
Battery not connected or out of range.
Flashes
"Battery Anomaly"
No
NOTE 1
•
Internal temperature out of range.
No LED signalling
Yes
•
Battery Test Failure.
•
Defective battery.
Turns on
"Battery Anomaly"
No
NOTE 2

Internal charger failure.
Flashes
"Equipment Anomaly"
No
NOTE 3
Non-Urgent
Failure
•
Battery temperature out of range.
No LED signalling
Yes
•
Battery temperature sensor failure.
Turns on
"Equipment Anomaly"
No
NOTE 4
•
Outputs 1, 2 or 3 out of range.
Flashes
"Output anomaly"
Yes / No
NOTE 5
•
Battery output overvoltage.
Flashes
"Battery Anomaly"
Yes / No
NOTE 6
End of Autonomy
•
Battery reaches minimum voltage.
No LED signalling
Yes
NOTE 1: Check that the voltage of the connected batteries is of the correct value (12V).
Otherwise, connect the appropriate batteries to the equipment.
NOTE 2: It is essential to change the battery as soon as possible, as it is reaching the end of
its useful life. Reset the equipment to restore normal operation. This alarm can also be
triggered if the battery is faulty or degraded (crossover).
NOTE 3: Temporarily, and very improbably, this error could occur for a few seconds during
start-up if, for some reason, the battery voltage is higher than the output voltage of the
product. In this case, the equipment will recover. If this is not the problem, the error will
persist and the system will require human action to be replaced.
NOTE 4: Check that the battery sensor is connected. If it is connected, replace it with a new
one, otherwise connect a sensor supplied by PREMIUM.
