Initial checks
This section offers some checks that you can make to help isolate the problem. The
checks are arranged in no particular order.
Checking Control Builder error code reference
An indication of a problem may be in the form of an error dialog that includes an error
message and possibly an error code in Control Builder.
The syntax for a typical Control Builder error message is as follows:
Connection to device is not open EPKS_E_CL_NOCONN(6L.101.3326)
In this syntax, the error code is the last four digits in the message or 3326.
Please refer to the Control Builder Error Codes Reference book for applicable error code
information.
Checking faceplate display and LEDs
Check the C300 Controller’s 4-character display and C300/IOTA LED indications and
compare results with data in the C300 Faceplate indicators/displays
section of this book.
