Protective Item Operating (Trip) Time Over-Current = O-TIME Phase Loss = O-TIME Locked Rotor = D-TIME+O-TIME LED
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: Orange LED Power / normal operating status: Green LED
Manual / Electric Reset
With test button held down,the orange 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 held down,the orange 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.
