initialization.
E0: CPU/Basic Module ROM error.
E1: CPU/Basic Module RAM error.
E2: No UART Module present.
E4: The power to the CPU/Basic Module has been switched off and on swiftly,
or some Module is missing during the power-off time.
E5: The connection between Modules is loose or broken.
A1: CPU/Basic Module execution failure.
A2: CPU/Basic Module can not communicate with Control Board.
10: The first UART Module initialization failure.
20: The second UART Module initialization failure.
30: The third UART Module initialization failure.
40: The forth UART Module initialization failure.
Hardware Causes and Solutions:
If the error message persists after check, return the unit for repair.
As “E0”, “E1” or “A1” occurs, usually you have to turn off and on the CPU
Module. If problem persists, the CPU Module might be defective.
As “E2” occurs, turn off the CPU Module, firmly connect the UART Modules,
and turn the power back on.
As “E4” occurs, usually you have to turn off the CPU/Basic Module, then turn on
at least time interval 3 seconds. Or check if the total number of ports (or
modules) is correct or not.
As “E5” occurs, it may indicates that the cables between modules should be
fastened carefully.
As “A2” occurs, check the link between CPU Module and Control Board is
fastened carefully.
As “10”, “20”, “30” or “40” occurs, make sure the connection between modules is
proper.
