CHAPTER 7 TROUBLESHOOTING

7.1 Initial Checks

7--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) Input type jumper connectors
Make sure that the jumper connectors are at their correct positions.
The following table shows the operations when the jumper connector
positions do not match the "input type" parameter settings.

(3) Wiring
Make sure that all cables are properly connected.
(4) Communications condition
When communicating using the RS-232C or RS-485 communications
interfaces, make sure that the baud rate and other communications
condition settings on the host computer and E5CK controller are
matching, and are within the permissible ranges.
If there appears to be nothing wrong after checking the E5CK controller,
and the same phenomenon continues, check the controller in more detail,
for example, on the error display.
