Shindaiwa DG250MI, DG150MI Operation Check, Earth leakage breaker relay has activated

Page 23
Ensure that the breakers and the switches of load(s) are positioned to OFF.
Ensure that the 3-Phase circuit breaker and the 1-Phase circuit breaker are positioned to OFF. Following the procedure in 9-1 Initializing / Preparation , start an engine.
Turn (Push-up) the 3-Phase「circuit breaker (lever) to ON 」position.
Push the test button (red) in the earth leakage relay unit. When the button is pushed, the earth leakage indicating lamp turns ON and the 3-Phase circuit breaker is positioned in the middle between ON and OFF positions simultaneously, the device works normally.
Push the reset button. The earth leakage indicating lamp (red) turns OFF subsequently. Turn (Push-down) the 3-Phase circuit breaker (lever) to OFF position.

7.3.2Operation Check

!Danger

: Electrical Shock

Before turning the 3-Phase circuit breaker to ON Position, ensure that the breaker or the switch of loads are positioned to OFF.

Operate the 3-Phase circuit breaker, well-communicating with The electrician by the load side.

Before operating the generator, check always if the device can work.

7.3.3 The earth leakage breaker relay has activated

⑥

In the event the earth leakage breaker relay has activated, the earth leakage indicating lamp Turns ON and the 3-Phase earth leakage breaker (lever) trips off to be positioned in the middle between ON and OFF positions.

In the above condition, even though you stop the engine once and start it again, the 3-Phase Circuit breaker (lever) does not restore to ON or OFF, and the reset button does not function,

because the device keeps detecting current leakage.

Stop the engine promptly and find the leakage point to repair. After repairing the leakage point(s), proceed with the following restoration steps.

(In the case the earth leakage indicating lamp does not turn to ON simultaneously, the cause is Over-Load or Short-Circuit.)
