E710
0001
When the main power is turned on, the communication IC (IPC) on the
reader controller PCB cannot be initialized.
0002
When the main power is turned on, the communication IC (IPC) on the DC
controller PCB cannot be initialized.
0003
When the main power is trend on, the communication IC (IPC) on the main
controller PCB cannot be initialized.
Main cause
The DC controller PCB is faulty. The reader controller PCB is faulty. The
machine controller PCB is faulty.
Action
Malfunction, PCBs
Turn off and then on the main power switch. Is the problem corrected?
YES: End.
NO:
If E7100001, replace the reader controller PCB.
If E710-002, replace the DC controller PCB.
