Test/reset button instructions: “TEST/RST” on the protector is the
test/reset button. Press it when the product is working normally, the
protector motions and the red light flashes; press it after a fault, the
protector is reset.
3.4
Adjustment of the setting current value: the protector uses the setting
knobs with indicating arrows. Based on the setting current value on the
nameplate, set the current according to the rated current and motor load
condition marked on the nameplate of the motor. Adjust the setting current
value of the protector to a scale equal to the rated current value marked on
the motor nameplate.
3.5
Commissioning: After confirming that the wiring and setting are correct,
power on the product and press the start button, then the motor should be
able to run normally and the (green) operation indicator on the panel
should be on. If the red indicator flashes, fine tune the setting value until
the red indicator light just does not flash.
Notes:
1 Check the performance of the protector on a regular basis. Perform overload
and loss of phase testing. The testing should be performed by professional
technicians to ensure the safety of electricity use.

The setting error of the protector shall not be greater than 5%. When the
current of the main circuit is within this range, the overload indicator may be on.

If the motor stops during its operation, the motor should be checked for loss
of phase or overload. First, check whether the temperature rise of the motor is
too high. If the temperature rise is too high, the stop may be caused by
overload; if not, the motion of the protector may be caused by the loss of phase
of the circuit. Check whether the three-phase power supply is normal, whether
the dynamic and static contacts of the AC contactor are in good contact, and
whether the three-phase power line of the motor has loosened; if everything
goes well but the motor still cannot be started, then carefully check whether the
self-locking contact of the AC contactor and the terminal wiring of the protector
have loosened. The motor cannot be started until the fault is eliminated. When
the fault is not eliminated, it cannot be started forcibly for fear of accidents.

Do not open the protector without permission, so as to avoid danger or
affecting the normal operation of the protector.
