Ammeter Function:
After the motor runs smoothly, turn the overcurrent setting knob slowly counter clockwise to the red indicator light, which is 100% of the actual running current. And then turn the knob clockwise to just turn off the red light at this point for the actual running current value of about 103%.
Run / Operation Indicator:
Relay Trip: Red LED
Power / normal operating status: Green LED
Manual / Electric Reset
With test button held down,the red LED is on and the product will trip after O-TIME.
The relay will be de-energized when RESET button is pushed or the control power is disconnected.
Set
After the installation is complete the settings as follows.
Set knob: D-TIME(Delay Time) Set two to three seconds longer than the motor starting time.
Set knob: O-TIME(Over-current run time) Set less than the motor's endurance time with over-current.
Set knob: Load(Rated Current) Set over 110% of the motor's rated current of under 120% of its operating current.
TEST Instruction
With test button ehld down,the red LED is on and the product will trip after O-TIME.
The relay will be de-energized when RESET button is pushed or the control power is disconnected.
