FIP1.4 FAN Error
Step
Check Yes No
Possible causative parts:
FAN MAIN (PL12.1.10)
FAN SUB (PL8.1.5)
LVPS (PL12.1.5)
HVPS/MCU (PL12.1.19)
1
Checking FAN MAIN for rotation (1)
Does FAN MAIN rotate, when the power is turned ON?
Go to step 2. Go to step 5.
2
Checking FAN SUB for rotation (1)
Does FAN SUB rotate, when the power is turned ON?
Go to step 3. Go to step 9.
3
Checking FAN MAIN for rotation (2)
Does FAN MAIN rotate in high-speed?
Checks by Chapter 2 Diagnostic [Fan Motor, High Speed
Test].
Go to step 4. Go to step 5.
4
Checking FAN SUB for rotation (2)
Does FAN SUB rotate in high-speed?
Checks by Chapter 2 Diagnostic [Fan Motor, High Speed
Test].
Replace HVPS/
MCU, and watch
FUN SUB for a
while.
(RRP12.10)
Go to step 9.
5
Checking the power to FAN MAIN
Is FAN MAIN connected correctly, and is the voltage
across P/J24-18 <=> P/J24-17, 24 VDC? (12 VDC, when
half-speed)
Go to step 6. Go to step 7.
6
Checking the FAN ALARM signal (1)
Is the voltage across P/J24-17 <=> P/J24-16, 0.82 VDC or
more?
Replace FAN
MAIN.
(RRP12.6)
Replace
HVPS/MCU.
(RRP12.10)
7
Checking after replacing FAN MAIN
Replace the FAN MAIN.
Does FAN Error occur when the power is turned ON?
Go to step 8. End of work
8
Checking after replacing LVPS
Replace the LVPS.
Does FAN Error occur when the power is turned ON?
Replace
HVPS/MCU.
(RRP12.10)
End of work
9
Checking the power to FAN SUB
Is FAN SUB connected correctly, and is the voltage across
P/J27-19 <=> P/J27-18, 24 VDC? (12 VDC, when half-
speed)
Go to step 10. Go to step 11.
10
Checking the FAN ALARM signal
Is the voltage across P/J27-18 <=> P/J27-17, 0.82 VDC or
more?
Replace FAN
SUB (RRP8.2)
Replace
HVPS/MCU.
(RRP12.10)
11
Checking after replacing FAN SUB
Replace the FAN SUB.
Does FAN Error occur when the power is turned ON?
Go to step 12. End of work
12
Checking after replacing LVPS
Replace the LVPS.
Does FAN Error occur when the power is turned ON?
Replace
HVPS/MCU.
(RRP12.10)
End of work
