ING LED blinks in red.
■
Symptom 4: The ALARM/WARNING LED is blinking in red.
■
Symptom 5: Channels are not identi fi ed.
Check Item Cause and Remedy
The protection function has tripped. • When the power is turned on, the ALARM/WARNING
LED may sometimes blink in red. This is a result of the
power disruption detection tripping due to the timing
when the power switch is turned on (this is not a fail-
ure). Turn off the power switch once and turn it back on
after waiting for at least 5 seconds.
Check Item Cause and Remedy
The LED starts blinking immediately
after the power is turned on. The
LED continues to blink even after the
unit is power-cycled.
• The power supply circuitry may have malfunctioned.
Immediately stop using the product and contact your
Kikusui agent or distributor for repairs.
The LED starts blinking
immediately after starting charge/
discharge.
• The power supply circuitry may have malfunctioned.
Immediately stop using the product and contact your
Kikusui agent or distributor for repairs.
The LED starts blinking in the
middle of the test.
• The overheat protection function of the power supply
circuit may have tripped.
The ambient temperature may exceed the operating
ambient temperature, the intake or exhaust port may be
blocked, the dust
fi lter may be clogged, or the fan may
have malfunctioned.
If there is no problem in the operating environment and
the LED is blinking, immediately stop using the prod-
uct and contact your Kikusui agent or distributor for
repairs.
Check Item Cause and Remedy
The STANDBY LED is not
illuminated.
• Check that the charge/discharge power supply unit is
installed properly. Also check the power switch and
power cord on the unit frame.
If the condition does not improve even after correcting
the problem, the charge/discharge power supply unit
may have malfunctioned.
The STANDBY LED is
illuminated.
• Check the TP-BUS wiring. In addition, check that the
frame address setting on the unit frame is not the same
as other frames.
If the condition does not improve, remove the charge/
discharge power supply unit from the unit frame and
check that dust is not present on the bottom of the rear
panel of the unit. In addition, check that dust is not
present on the inside of the unit frame (section where
the unit engages with the frame)*1.
*1 This is to eliminate optical communication obstruction between the unit frame and the charge/
discharge power supply unit.
