Adjustments
On the rear side of the unit are a number of potentiometers and DIP switches for programming of
the unit:
4.1
Check synchronizer relay
On DIP switch S1 pin 1 the check synchronizer relay can be programmed to offer a constant closing
signal that remains activated as long as voltage-, frequency-, and phase difference between
generator and busbar voltage are within limits for automatic closure, or a pulse signal of 0,4 or 0,8s.
S1, pin1
OFF, pulse signal
S1, pin1
ON, constant signal
In case S1, pin1 is in OFF position, S1, pin2 can be used for programming the length of the closing
pulse:
S1, pin 2
OFF, closing pulse of 0,4s
S1, pin 2
ON, closing pulse of 0,8s
On potentiometer P1 the acceptable limits for voltage-, frequency- and phase deviation can be
adjusted. It is a combined setting on one potentiometer. Narrowest limits are adjusted by turning P1
counter clockwise until end position. Then the limits are as follows:
∆U = 10%
∆f = 0,15Hz
∆φ = 6
