Cut off the link between 10 and 11 terminal. Operate exactly like that for current

relay to test operation current and return current, then step up AC current to the

tested operation current value, record the present voltage, universal meter can

be used to test the voltage between the two ends of J1

No brake

Starting ampere-turns test

It is not normal inspection item. Put in all the working winding 20 circuits,

connect the short-circuit of 10 and 11, input AC current from 3 and 8, input

contact operation signal from 5, 7 contact end, test like that for current relay.

The braking performance test

When make periodic inspection, just test Φ=0°and Action ampere-turns value when

Brake ampere-turns is 280
