•Up to ten steps of remotely activated voltage reduction are available. The voltage
reduction steps are activated when FC 70 is set to Remote/Pulse and a momentary pulse is
applied to the appropriate input terminal.
•FC 76 defines the number of steps selected for pulsed voltage reduction. The percentage of
voltage reduction of each step is defined at FC 77.
•See
Section 6: Control Features: Analog SCADA
•If an alternate configuration is active, the fourth LCD line displays which one is active,
e.g. (ALT CONFIG 1).
