Page 3: Preface
User Manual M8100 1 Preface This manual describes the M8100 Synchroscope with built-in check synchronizer relay and dead bus closure function. 2 Function The M8100 Synchroscope provides illuminated indication of the actual phase difference between generator voltage and bus voltage. If the vector and the light spot turn clockwise, the generator frequency is too high and must be reduced. -
Page 4: Adjustments
User Manual M8100 4 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. -
Page 5: Dead Bus Closure
User Manual M8100 The highest tolerance is adjusted by turning the potentiometer P1 clockwise until end position. Then the limits are as follows: ∆U = 20% ∆f = 0,3Hz ◦ ∆φ = 12 4.2 Dead bus closure This function enables the built-in check synchronizer relay to close the circuit breaker even though there is no voltage on the busbar. -
