Protection

• Protective Item Operating (Trip) TimeOver-Current = O-TIMEPhase Loss = O-TIMELocked 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: Red LED
  Power / normal operating status: Green LED

Manual / Electric Reset

• 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.

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 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.
