8.1 Initial Checks

8--2
If trouble occurs, first of all check the following.
(1) Power supply
Make sure that the power supply is ON. Also, make sure that the
power supply is within the rated voltage range.
(2) Wiring
Make sure that all cables are properly connected.
(3) Communications condition
When communicating using the RS-232C, RS-422 or RS-485 commu-
nications interfaces, make sure that the baud rate and other commu-
nications condition settings on the host computer and E5AK control-
ler are matching, and are within the permissible ranges.
If there appears to be nothing wrong after checking the E5AK controller,
and the same phenomenon continues, check the controller in more detail,
for example, on the error display.
