• Code: 227-0001-04
• Description: Power supply error
• Causes: The Reader Controller PCB did not detect 24 V when the main power was turned ON.
• Remedy: [Related parts] R1.00 - Harness between the Reader Controller PCB (UN_BO1/J104) and the DADF Driver PCB (PCB1/ J402) - Harness between the Reader Controller PCB (UN_BO1/J101) and the AC Driver PCB (UN30/ J118) - Harness between the AC Driver PCB (UN30/J112) and the 12V/24V Power Supply PCB (UN5/ CN52) - Reader Controller PCB (UN_BO1) - DADF Driver PCB (PCB1) - AC Driver PCB (UN30) - 12V/24V Power Supply PCB (UN5) [Remedy] Check/replace the related harness/cable, connector and parts.
