Description

Three Phase Monitoring Electronic Overload Relay For Lifts Elevators

Setting method

1. First adjust the knob clockwise to the max. Start the motor until the motor is in normal operating condition.


2. Then slowly adjust the knob anti-clockwise till the overload indicatorlights up, so the protector is just in a critical state of overload.


3. After that slowly adjust the knob clockwise till the overload indicatorgoes out,setting completed.
