Zero cross-error (relay contact error)
Zero cross processing executed for 0.5 seconds, but relay shut OFF/ON when
zero cross was not generated even once. The process is done three times.
• Damaged fusion relay (contact open)
• Fusion relay circuit defective
• PSU fuse (24VS) blown
Check if the SC occurs by turning the power OFF then ON. If the SC occurs again,
do the following steps. Check if the SC reoccurs by cycling the power after each
step.
1. Replace the PSU (PCB4).
2. Check the harness connections between the PSU (PCB4) and the EGB
(PCB1).
3. Replace the harnesses between the PSU (PCB4) and the EGB (PCB1).
4. Replace the EGB (PCB1).

D
Zero cross-error (abnormally low frequency)
Zero cross count processing is executed at 0.5 seconds intervals.
• When the zero-cross count is 45 to 54, the frequency is set to 50 Hz.
• When the zero-cross count is 55 to 65, the frequency is set to 60 Hz.
• For cases other than the above ranges, the frequency is abnormal.
When the frequency abnormality is detected 10 times, and the number of low-
frequency detections is 2 or more out of 10 times.
Frequency is the input power source is unstable.
Check if the SC occurs by turning the power OFF then ON. If the SC occurs again,
do the following steps. Check if the SC reoccurs by cycling the power after each
step.
1. Replace the PSU (PCB4).
2. Check the harness connections between the PSU (PCB4) and the EGB
(PCB1).
3. Replace the harnesses between the PSU (PCB4) and the EGB (PCB1).
4. Replace the EGB (PCB1).

Low-temperature detected (Fusing thermopile (TH2))
Measurement is started 60 seconds after turning the fusing lamp ON, and the
fusing thermopile (TH2) has detected -100 °C from the target temperature
continuously for 60 seconds.
