Target cos : target displacement power factor.
The target cos value can be set between 0.70 inductive and 0.70 capacitive.
indicates an inductive cos and
Night cos : alternative displacement power factor (disabled by default).
Switching from the target cos to the target night cos is performed with an external signal applied on the external
digital input IN 1 +/- (description in paragraph 2.4).
Reg. cos : alternative target displacement power factor. Activated when power flow is reversed: P < 0 (disabled by
default).
Alarm: alarm relay parameters can be set for the Alarm cos condition: The Alarm cos condition is fulfilled when:
all the capacitor steps are ON and the actual cos value is below the alarm cos threshold value such that at least
one step is needed.
– Alarm delay: duration of alarm cos condition before the relay closes.
– Alarm reset delay: delay time before the relay opens after the alarm condition has disappeared.
– Alarm cos : threshold value
