Switching performance window:
Press
W
to select submenus.
The default switching performance settings (default settings) are displayed
in the submenus of this window. These settings apply to most compensation
systems.
NOTE
Check all parameters to ensure that they do not deviate from the specifi cations
for this system.
The following submenus are available to aff ect switching performance:
Hysteresis connection (default setting 100%, setting range 70 to 150 %): This
value defi nes the controller switch-on criterion. This means the controller
would switch on at 100% missing compensation power relative to the small-
est capacitor stage of the system.
Hysteresis switch-off (default setting 100%, setting range 70 to 150 %): This
value defi nes the controller switch-off criterion. This means the controller
would switch off at 100 % overcompensation relative to the smallest capacitor
stage of the system.
Alarm delay (default setting 1200 seconds, setting range 0 to 3000 seconds):
This value defi nes the time until the message "PFC too small" is displayed.
If the set target cos phi is not reached despite all available stages being
switched on, this message is displayed after the set alarm delay time has
elapsed.
Idle time (default setting for thyristor stages 20 msec, setting range 20 to
9999 msec, for contactor stages 10 sec, setting range 0 to 300 sec): This value
defi nes the time the controller is idle after compensation before another
switching operation is performed (connection or disconnection).
