11. Set up
1. Set START TIME knob (start-up delay) at the start-up time if the start-up time is known.
Set START TIME knob (start-up delay) at the maximum if the start-up time is unknown.
2. Set SHOCK TIME knob (trip delay timer) at the desired trip time.
3. Set CURRENT knob (trip current) at the rated current of the motor.
4. Supply control voltage to the Shock Relay. Then confirm that the SHOCK TIME activates
its built-in output relay – the contacts will change state.
5. Press and hold the TEST button. Confirm that the Shock Relay lights its OC LED and
trips after total of the START TIME and SHOCK TIME. Confirm that this also deactivates
the built-in output relay.
6. Press the RESET button. Confirm that the OC LED turns off and that the built-in output
relay activates.
7. Start the motor and check that the start-up time was correctly set. Then slowly turn the
CURRENT knob counter clockwise until the Shock Relay flashes its LED. At this point,
the CURRENT knob indicates 100
％
of the motor running current.
8. Set the CURRENT knob at the proper trip current, this is commonly at 110
％
of the actual
motor running current.
9. Recheck and adjust the START TIME knob so that it is a little longer than the normal
start-up time.
