Problem
Product common troubleshooting - external indicator
Datetime: 2018-07-28 Visit: 3808
The capacitor is not put in, the external indicator light is on.
answer:
1. A total complement capacitor product, when the external indicator light is energized at the common end, and the capacitor itself is not closed, the external indicator light will be on due to the "inductive power", and the brightness is slightly weaker than the normal brightness. - Closing the miniature circuit breaker is normal;
2. The external lamp common terminal or capacitor main power phase sequence is not wired according to the actual requirements of the manual or the drawing - a total of two capacitors are added: when not input, the external terminal output power is C phase, after input, the output is phase B (so The common terminal is connected to phase C, the capacitor is not thrown, the indicator light is C phase at both ends, the voltage is 0, the light is not bright); the common anti-harmonic: when not input, the external terminal output power is B phase, after input, output For phase C;
