3.6.4 Set value checking code storage area for channels 1 through 4
This area is used to check if the digital value is within or out of the setting range. One of the following
checking codes is stored when the digital value lower or higher than the setting range is set.
Check code list
Check code Description
000FH A digital value which exceeds the setting range was set.
00F0H A digital value which is below the setting range was set.
00FFH
Both a digital value below the setting range and digital value exceeding the setting
range were set.
For example, the 00FF
H check code is stored if a digital value exceeding the valid
range is written, and then, without the check code being reset, a digital value that
falls short of the valid range is written.
(1) The check code once stored is not reset even if the set value is set to within the valid setting
allowed range.
(2) The storage area or the set value check code is reset by turning on the error reset request flag
(RY (n+1) A).
3.6.5 Error code
(1) If an error occurs when starting the module or writing data to the AJ65BT-64DAV/DAI (the RUN
LED flashes), the following error code is stored in the error code (RWrn+4) in the
AJ65BT-64DAV/DAI remote register.

PROM became faulty.
Power-cycle the AJ65BT-64DAV/DAI again.
If this recurs, the module may be faulty.
Consult your local servicing company, dealer
or our branch office.
The indicates the channel number where the error occurred.
(2) When multiple errors occurred, the error code of the first error is stored, but the other errors are
not stored.
(3) The error code reset is performed by turning on the error reset request flag (RY (n+1) A).
When the error code is “999”, however, it cannot be reset because the hardware of the module is
faulty.
