PROBLEM SOLVING
• A38, A39, A40, A41: external alarm 1, 2, 3, 4.
One of the ADC card inputs has been activated; check the situation of the devices connected to this card.
• 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.
9.2 UPS alarms.

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).

The equipment has to undergo periodic checks by the support service in order to ensure optimum perform-
ance and efficiency. If the “Programmed Control” signal appears on the mimic panel, the equipment should
be inspected by a technician trained accordingly.
