FIP1.4 Fan Error

Step
Possible causes:
FAN MAIN (PL1.1.14)
FAN SUB (PL8.1.5)
LVPS (PL12.1.5)
HVPS/MCU (PL12.1.19)
Checking FAN MAIN for rotation (1).
1
Does FAN MAIN rotate, when the power is turned ON?
Checking FAN SUB for rotation (1).
2
Does FAN SUB rotate, when the power is turned ON?
Checking FAN MAIN for rotation (2).
Does FAN MAIN rotate in high-speed?
3
Check using Chapter 2 Diagnostic [Fan Motor, High
Speed Test].
Checking FAN SUB for rotation (2).
Does FAN SUB rotate in high-speed?
4
Check using Chapter 2 Diagnostic [Fan Motor, High
Speed Test].
Checking the power to FAN MAIN.
Is FAN MAIN connected correctly, and is the voltage
5
across P/J24-18(+) and P/J24-17(-), 24 VDC?
(12 VDC, when half-speed)?
Checking the FAN ALARM signal (1).
6 Is the voltage across P/J24-17(+) and P/J24-16(-), 0.82
VDC or more?
Checking after replacing FAN MAIN
7 Replace the FAN MAIN.
Does FAN Error occur when the power is turned ON?
Checking after replacing LVPS
8 Replace the LVPS.
Does FAN Error occur when the power is turned ON?
Checking the power to FAN SUB
Is FAN SUB connected correctly, and is the voltage
9
across P/J27-19(+) and P/J27-18(-), 24 VDC?
(12 VDC, when half-speed)?
Checking the FAN ALARM signal
10 Is the voltage across P/J27-18(+) and P/J27-17(-), 0.82
VDC or more?
Checking after replacing FAN SUB
11 Replace the FAN SUB.
