If the voltage dip lasts longer than two cycles, or the voltage drops
below the minimum required to power the device correctly, the "power-
fail" cycle will be activated: REGO will instantly de-energize all the
output relays until the voltage returns to normal levels or disappears
completely to prevent undesired operations on the capacitor banks.
13.6 DISPLAY OF ALARM COUNTERS
The user can see how many times the controller has gone into an
alarm status due to overvoltage and excessive harmonic distortion.
To view the counters, press L + DATA. The letters "ALC" will appear
and the L LED will flash.
Ex.
Press the corresponding L key to access the settings. The s and M
LEDs will flash and the first alarm (t.h.d.) will be displayed in turn with
the number of activations; to view the next alarm (UFF) press the DATA
key. Press the DATA key again to exit the function.
These counters cannot be cleared.
13.7 CHANGING THE ALARM ACTIVATION MODES
The user can change the activation modes of the controller alarms. In
particular, as regards the signals and protections for power factor
correction failures, overvoltage, overtemperature and excessive
harmonic distortion, it is possible to set:
