Signals And Alarms; Signaling Of Power Factor Correction Failure - Ducati Energia REGO 5 Manuel D'instruction

13) SIGNALS AND ALARMS

The REGO controller features a device for signaling overvoltage and
power factor correction failures as well as alarms which are activated
when an overtemperature protection trips or in the event of excessive
harmonic distortion and voltage drops or mains dips. When a protection
trips, the ALARM LED will light up and the NC contact will close to
remotely signal the alarm status. With the exception of the device for
signaling power factor correction failures and overvoltage, the
protections will cause the capacitor banks to be switched off.

13.1 SIGNALING OF POWER FACTOR CORRECTION FAILURE

This signal is activated when the system power factor remains below
the set value for more than two consecutive hours (reentries of up to 1
minute are allowed) with all the capacitor banks switched on. This
signaling function is not active in the manual mode. When a power
factor correction failure is signaled:
– the initials "A.L.A." will be displayed in turn with "C.O.S. " and the
last value measured (these digits will also be separated by ...)
Ex.
– the ALARM LED situated on the front panel of the controller will
light up.
– the alarm relay contact connected to the controller terminal block
will open.
