E808-0001 = Title Zero cross signal detection error
Detection description=
Unable to detect 43 to 57Hz for 5000 msec or longer at the start of zero cross detection
Remedy=Electrical trouble with failed zero cross signal
1. Check failure between the AC Driver PCB (UN14/ J122) and the DC Controller PCB (UN09/ J10). (trapped cable, open circuit, connector disconnection) -> Replace the part in the case of trapped cable/open circuit
2. Replace the AC Driver PCB (UN14)
3. Replace the DC Controller PCB (UN09)
4. Check the power supply condition at the customer site.
When it is below 43 to 57Hz, ask for a construction work.

Detection description=
Unable to detect 43 to 57Hz for 500 msec or longer after confirmation of a zero cross cycle
Remedy=Electrical trouble with failed zero cross signal
