When safety shutdown occurs, LED display reports the cause by using the Lighting patterns as indicated below. Since there are
various failure items in WAX model. Light blinking is used so that shutdown causes can be judged from the number of blinking times.
The items corresponding to the number of blinking times are indicated as follows

The items corresponding to the number of blinking times are indicated as follows
Example : The figure above shows a LED display when SHUTDOWN is caused by an DC. Alert 2. It repeats flashing for a
specified number of times in 0.3 sec/cycle, has a 2 seconds interval of lighting-off, and again repeats flashing for the
same number of times. Please note that a 2 seconds interval of lighting-off is fixed regardless of abnormal state types.

Main voltage trouble (REG12V)
•
Power Supply voltage error
3 times
DC_ALERT 1 (D.3.3V)
•
Confirm, which the voltage the right voltage doesn’t
appear about D3. 3V,VDDMQO(=2.5V)
•
If it is D3. 3V,VDDMQO(=2.5V), confirm about 3.3V input
IC7001 5th Pin and F7000 is not open.
•
If it is VD1.8V, confirm about 3.3V input IC7002 5th Pin
and F7000 is not open.
•
If it is VD1.8V, confirm about 3.3V input IC7000 12th Pin
and PS7000 is not open.
4 times
DC_ALERT 2 (FE3.3V)
5 times
DC_ALERT 3 (PANEL 12V)
•
Confirm, the voltage of REG12V is about 12V.
•
If no voltage is on REG12V, Confirm R3031, R3034,
R3037 is mounted.
•
If no voltage is on REG12V, Confirm REG12V is short-
circuits in GND.
•
If REG12V is not short-circuits in GND, change PWB to
new one.
6 times
BackLight trouble (PANE_DET=0V)
•
Confirm, about D3. 3 input to Q4014/Q4015.
•
If 6 times, change backlight-board.
7 times
Set-Temperature trouble
•
Confirm, heat sink and heat sheet adhere to IC4500.
•
If set isn’t shutdown, BH-board temp-trouble.
8 times
Audio trouble (AU_PROT)
•
Confirm, the right voltage appears about D3. 3V,
VDDMQO(=2.5V), VD1_8, D5V.
•
If the output voltage is right, confirm whether X4500 does
an oscillation definitely.
•
Change IC4500 to new one.
9 times
FAN trouble
•
Trouble-Info from BH-board-ICbus.
10 times
Digital-FE trouble
•
No communication from FE-IC.
11 times
Trident trouble
•
No communication from Trident-bus.
12 times
HFR trouble
•
BH-board communication error/Voltage trouble in BH
board.
13 times
Balancer-board trouble
•
Confirm, about D3. 3 input to Q4014/Q4015.
(PANEL_DET=1.6V)
•
If 13 times, change Balancer-board.
