#1 The
power
lamp does

when the
power is
turned on.
Probable causes
1. Conversion transformer improperly
wired (for 100 V, 110V specification)
To the power supply
To the power switch
(For 240 V, 380 V, 400 V, and 415 V
specifications)
To the power supply circuit board
To the power switch
(For 200 V, 220 V, and 230 V
specifications)
No conversion transformer is
installed.
2. Conversion transformer defective
3. Power supply cable defective
Check/repair/adjust
Note: Before adjustment, be sure to check that the
power is turned off to prevent electric shock.
If the power is turned on, turn off the power,
and wait at least 5 minutes.
• Conversion in the control box
Check the transformer is correctly and securely wired
to the terminals.
(For 200 V, 220 V, and 230 V specifications, this is not
necessary.)
Separate P4 (ACIN) connectors on the power supply
circuit board, and check there is continuity between
pins 1 and 2 in the connector on the cable.
If there is no continuity, replace the conversion
transformer.
(For 200 V, 220 V, and 230 V specifications, this is not
necessary.)
Separate P4 (ACIN) connectors on the power supply
circuit board, turn on the power, and measure the
voltage across pins 1 and 2 in the connector on the
cable.
If the voltage is as shown in the table below, the
power supply cable is not defective.
After checking, turn off the power, and rejoin P4
connectors.
