3.3 Adjustment and inspection
3.3.1 Check if the rated voltage of the starter Ue is consistent with the actual
control voltage of power.
3.3.2 Check if the rated operating current of the starter is within its setting
current range.
3.3.3 Check if the starter can operate smoothly: press down the green
button of the starter or turn the knob to ON position, flip the guide plate
beside the TEST mark on the cover according to the direction shown by the
arrow. You can hear the operation sound of the contact, and the green
button will bounce back or the knob will be turned to OFF position. Replace
the starter if there is any abnormality.
3.3.4 The operating current of the starter (setting current value of thermal
element) should be determined by the rated current of the motor. If the
setting current value between two scales is required, turn the cam slightly
accordingly. User can make adjustment during operation.
