•
The G3PX does not operate or is in abnormal operation.
Make sure that all input terminals are connected properly with no
mistakes in polarity.
Make sure that the internal DUTY adjuster is not set to the
farthest clockwise position.
Make sure that the frequency used by the G3PX (i.e., 50 or 60
Hz) is set properly. (This applies to the EC models.)
•
Temperature control with a Voltage-output Temperature
Controller is not smooth.
Make sure that the controlled soft-start up/down time has been
adjusted properly. If not, turn the TIME adjuster counterclockwise

Remedy 2: When the supply current is less than 50%, increase
the number of turns of wire on the current transformer. When the
supply current is 50% of the rated current, the wires must be
coiled twice on the CT Unit. When the supply current is 25% of the
rated current, the wires must be coiled three to four times on the
CT Unit.

Be sure to press the RESET button with power supplied to the
G3PX.
The following wiring will be required if the breaker or contactor
connected between the power supply and the G3PX is operated
by the relay output of the G3PX.
