1. Check List Before Use

Please make sure that the product specifications are the same as ordered.
Check to ensure that no damage has occurred during delivery, and that there are no defects or missing items.

2. Operation Time Set-up

Precise set-up is required, since it works after the O-TIME is passed. The operating time is as marked as on the scale of control knob.
(1) Operation Time Set-up
O-TIME is Controllable in a range of 0.2~30 seconds.
(2) It will trip after O-TIME is passed, as low voltage occurs while operating.

3. Rated Current Set-up

(1) Turn on the generator after setting up the optimal low voltage with the control knob.
(2) While slowly turning the control knob counter-clock wise, the point at which the low voltage indicator lamp (O.L) turns off is the point at which the actual voltage (100%) has been reached.

4. To Confirm Operating

(1) While the power is on, if the TEST button is pressed, the low voltage indicator lamp on the generator protective relay will illuminate, the power lamp will turn off, and it trips.

(2) When it trips, press the RESET button. The low voltage indicator lamp will turn off, and the power lamp will illuminate as the initial state is recovered.
