CHAPTER 8 TROUBLESHOOTING

E5EK

8--2

8.1 Initial Checks

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 conditions

When communicating via the RS-232C, RS-422 or RS-485 inter-
faces, make sure that the baud rate and other communications
condition settings on the host computer and E5EK-T controller are
matching, and are within the permissible ranges.

If there appears to be nothing wrong after checking the E5EK-T con-
troller, and the same phenomenon continues, check the controller in
more detail, for example, on the error display.
