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.
Features

2) Three-phase monitoring of overload, phase loss, phase unbalance
3) Powered by the measuring circuit
4) 1 NC SCR output contact
5) 4 LEDs for status indication
Protecive Functions
1) Overload
2) Phase Loss
3) Phase Unbalance
