PROBLEM SOLVING
• A38, A39, A40, A41: external alarm 1, 2, 3, 4.
One of the ADC PCB inputs has been activated; check the situation of the devices connected to this PCB.
• A56, A57: generator general alarm.
The generator has sent an alarm; check directly on the GE.
• A61: wrong phase cycle direction.
The phase cycle sequence is incorrect. In this case, invert two phases of the input mains. For a UPS with sepa-
rate auxiliary mains, exchange the two phases of the auxiliary mains only.
10.2 UPS ALARMS.
• A01: battery alarm.
Failure or problem on the battery circuit. Check that the battery switch is closed.
• A18: inverter blocked due to overload.
Reduce the load rate applied to the UPS and reset the alarms.
• A20: wrong con guration.
Error in the con guration parameters; please contact the support service.
• A30: block due to overload.
Reduce the load rate applied to the UPS and reset the alarms.
• A42: T.Service general alarm.
The MASTERYS™ products can be remotely serviced. This alarm indicates that a procedure for analysing the
UPS failure has been activated by the support centre (if an e-service contract has been concluded).
• A44: programmed control.
The equipment has to undergo periodic checks by the support service in order to ensure optimum perform-
ance and e ciency. If the “Programmed Control” signal appears on the mimic panel, the equipment should
be inspected by an adequately trained technician.
• A47: maximum battery temperature.
The temperature of the battery cabinet (or of the battery room) is higher than the maximum allowed. Check
the ventilation or air conditioning system in the premises.
• A59: battery circuit open.
Battery switch open.
• A60: fan failure.
Fault in the ventilation system; check that the air inlet at the front and the air outlet of the UPS are not ob-
structed.
