Troubleshooting

2-2. Self Diagnostic Mode

This unit allows executing the nine self diagnostic tests
below. (Refer to Section 2-2-3, “Starting and Quitting of
the Self Diagnostic Mode”.)

1. ROM version display

Displays the current ROM version on the 7SEG LED.

2. ROM test

Performs a ROM checksum test to check the memory
operation.

3. RAM test

Performs a RAM read/write test to check the memory
operation.

4. NV-RAM test

Performs an NV-RAM read/write test to check the
memory operation.

5. LED test

Checks that all the LEDs light.

6. 7SEG LED test

Performs a 7SEG LED light test to check the decoding
operation for numeric display.

7. Switch test

Checks the operation of a pushbutton switch.

8. Rotary encoder test

Checks the operation of a rotary encoder.

9. RS-422A test

Performs an RS-422A loop-back test to check the
communication operation.

2-1. Normal Diagnostic Function (Power

ON Test)

This unit executes the tests below automatically when
turning the power ON.

1. ROM (IC103 on the CP-364 board) test

(Error :

“

”

)

This performs a ROM checksum test.
The “

” display blinks on the 7SEG LED and the

operation stops when an error occurs. Replace the
ROM.

2. RAM (IC104 on the CP-364 board) test

(Error :

“

”

)

This performs a RAM read/write test (in which cycle
data “

” through “

”, “

” and “

” are written

and read for comparison).
The “

” display blinks on the 7SEG LED and the

operation stops when an error occurs. Replace the
RAM.

3. NV-RAM (IC201, 203 on the CP-364 board) test

(Error :

“

”

)

This performs an NV-RAM read/write test (in which
data “

” and “

” are written and read for compari-

son). But the data of the memory does not change.
The “

” display blinks on the 7SEG LED and the

operation stops when an error occurs. Replace the
NV-RAM.

4. NV-RAM (IC201, 203 on the CP-364 board)

checksum test (Error :

“

”

)

This performs an NV-RAM checksum test.
The “

” display blinks on the 7SEG LED and the

operation stops when an error occurs. Replace the
NV-RAM.

5. Switch short test (Error :

“

”

)

This test confirms that a switch is not short-circuited.
If the switch is short-circuited, the LED of the switch
blinks and the “

” display blinks on the 7SEG LED

and the operation stops. Replace the short-circuited
switch.
