Troubleshooting and Reconfiguring
This chapter explains how to troubleshoot and reconfigure the
controller.
When There is a Problem
The controller is only one part of your control system. Often,
what appears to be a problem with the controller is really a
problem with other equipment, so check these things first:
•
The controller is installed correctly. (See the Installation
chapter.)
• Sensors, such as thermocouples and RTDs, are installed
correctly and working.
NOTE! If you suspect your controller has been dam-
aged, 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 Watlow technical support (see
page 1). If you need to return the unit to Watlow Anafaze for
testing and repair, Customer Service will issue you an RMA
number (see Returning a Unit on page 158).
