Connect like above graph. Cut off the link between (4) and (6), the action loop take
39 turns, the brake circuit takes 14 turns, the regulator (minimum capacity 5KVA)
and the instrument uses the same 220V power supply, adjust the brake Current to
the required ampere turns, according to the AC relay to make the action current. If
the action ampoule is completely wrong, it is possible that the phase angle of the
braking current and the operating current is 180 ° and the braking current is
reversed. If the instrument uses a phase in the three-phase, the regulator uses the
other phase, and the phase angle of 60 ° can be obtained by changing the phase
difference and booster positive and negative connection. If externally connect phase
shifter, can get 0 ~ 360 ° phase angle.
2) The whole group of volt-ampere characteristics test, according to the following
diagram wiring:
Put AC current on winding (3), (8), read voltage by a multi-meter from (9), (10),
select 1 to the AC current gear, step up current to the required turns number, read
voltage value of the executive component terminal when turns is 1 times, 2 times, 5
times.
Ampere-turn test under setting position is the same as that of the current relay

Matters Need Attention
1. For safety reasons, do not turn on the power switch when the instrument and the
relay are connected. Check that the wiring is correct and then turn on the power
switch.
2. For the accuracy of the instrument, please preheat 5 to 10 minutes before the test.
3. When measuring the contact action time, the millisecond meter should be cleared
after adding the rating.
4. When the instrument is not working properly, please check the various insurance
