• The Level indicator is not OFF with a 0% input signal (G3PX-
2
@
0EUN Series).
Make sure that the BASE UP adjuster has been turned counter-
clockwise to the minimum setting.
• The OPEN indicator of a multiple heater open circuit detection
model is lit at the initial stage (G3PX-2
@
0EHN Series).
Make sure that the initial settings are OK. If not, readjust the
G3PX.
Make sure that terminals 18 and 19 are open if the supply
frequency is 50 Hz. These terminals must be short-circuited if the
supply frequency is 60 Hz.
Make sure that the load current is large enough.
• The Level indicator LEDs of a constant-current model are all lit and
no power control operation is possible.
Make sure that the load current is large enough.
Countermeasure 1: Adjust the CUR LIM adjuster so that the LED
on the farthest right of the Level indicator is OFF.
Countermeasure 2: When the supply current is less than 50%,
increase the number of turns. 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.
• No reset will be performed even if the RESET button is pressed.
Check whether the RESET button is pressed while there is nothing
input into to power supply terminals 8 and 10 or 9 and 10 of the
G3PX.
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.
