Settings:
Attenuation (DF) = Reduction of the display uctuations,
the measuring cycle of the controller is not inuenced.
Idle time (t-idle) = Starts at compensation. After the idle time has expired,
the next switching operation follows
Alarm delay = Concerns the FTS message (facility too small), i.e. all stages are
(t-alarm) hooked up, and the set alarm CosPhi is not reached.
After the set time has expired an alarm message is issued
Hysteresis (hyst.) = Refers to the smallest available stage power and
the overcompensation or undercompensation, i.e. the hooking
up or switching o starts at the percentage set
Switch attenuation = The time set denes the interval between two
switching operations
Operating cycle limit = When the set value is reached, a message is
issued. The value is based on the specication of the
contactor manufacturer.
Switch-o threshold = Overvoltage switch-o to protect the system,
Lim U i.e. switching o the stages starts when
the set limit is exceeded
(hysteresis = 1% of the measuring voltage)
Switch-o threshold
Lim Ie + = Overcurrent value in induced current measurement
Switch-o threshold
Lim Ie - = Undercurrent value in induced current measurement
System operation
