1. When commissioning, set start delay (D-Time knob) to known
motor run-up time, or to the maximum, if not known.
2. Set trip delay time (O-Time knob) to desired trip delay time.
3. Set load current (LOAD knob) at the rated full load or desired
currents.
4. With connections made and control power on, depress TEST
button and hold. Verify the orange LED illuminates and the
internal relay should switch contacts after the sum of D-Time
and O-Time. Depress RESET button.
5. Start the motor and notice run-up time. Then, slowly turn the
LOAD knob , until orange LED flashes, where the 100% of
the actual load current is indicated. Set the LOAD knob to the
desired trip currents.
110～125% Setting of running current is recommended.
6. Reset D-Time knob setting to normal run-up time.
7. Periodic testing with TEST button is recommended to ensure
the full protection and regularly as a preventive maintenance.
