Overcurrent. The
current measure
exceeds Inom + 20%. Possible causes: C/K incorrectly adjusted
The alarm output disconnects, if triggered (see section
3.3). The unit normally tries to regulate, although it
could have a regulation error.
Overvoltage. The
voltage measure
exceeds Vnom +15%. Possible causes: Bad voltage connection

8 MAINTENANCE
The computer MAX 6f 12Vdc regulator does not require special maintenance. Try to avoid any type of
adjustment, maintenance or repairs while the unit is open as much as possible. If this cannot be avoided,
only qualified and trained staff should carry out these operations.
Disconnect the unit from all power supplies before performing any connection modifications, relocation,
maintenance or repair operations. If any operational faults in the unit or in its protection elements are
suspected, remove the unit from service and make sure that accidental connection is not possible. The
design of the unit makes it easy to replace in the event of a fault.
