Troubleshooting and Reconfiguring
The first sections of this chapter describe general
troubleshooting for the CAS200. Later sections describe
specific procedures such as checking an input, changing the
EPROM, and testing the scanner
When There is a Problem
Even in stand-alone systems, the CAS200 is only part of
your control system. Often, what appears to be a problem
with the CAS200 is really a problem with other equipment,
so check these things first:
• Scanner is installed correctly. (See Chapter 2 ,
Installation on page 7, for help.)
• Inputs, like thermocouples, are installed correctly and
working.
NOTE! If you suspect your scanner has been damaged,
do not attempt to repair it yourself, or you may
void the warranty.
If the troubleshooting procedures in this chapter do not
solve your system’s problems, call the Technical Services
department for additional troubleshooting help. If you need
to return the unit to Watlow Anafaze for testing and repair,
Customer Services will issue you an RMA number. See
Returning Your Unit on page 68.
