SECTION 6 - TROUBLESHOOTING
INTRODUCTION
This section explains how to troubleshoot basic module and
system failures. This section includes flowcharts and tables
containing troubleshooting procedures and corrective action.
HOW TO USE THIS SECTION
You can effectively troubleshoot a failure by using the flow-
charts to isolate the failure. After locating the failure, refer to
the text or other documents for more information about the
failure and the corrective action. You will need product
instructions for the controller or processor module, the opera-
tor interface (i.e., OIS, PCV, CTM/CTT) and the
. Contact the manufacturer for informa-
tion about the process hardware in the control loop.
The first part of this section covers off-line failures. If the fail-
ure is preventing calibration, tuning or module start-up, go to
and the steps of the troubleshooting pro-
cedure. The second part covers failures during operation. If the
failure occurs during operation, go to
the steps of the troubleshooting procedure.
NOTE: Troubleshooting involves physical contact with the system,
including the handling of boards with electrostatic sensitive devices.
To avoid creating additional problems while troubleshooting, always
use Bailey Controls Field Static Kit (P/N 1948385A1) when working
with the modules. The kit is designed to connect a technician and
the static dissipative work surface to the same ground point to pre-
vent damage to the modules by electrostatic discharge.
OFF-LINE FAILURE
This part of the troubleshooting section covers off-line failures
and how to troubleshoot those failures. Off-line failures occur
during module calibration and are a result of improper or
incomplete installation or calibration.
If the HSS fails to calibrate after completing the installation
procedure:
1. Locate the cause of the failure using the troubleshooting
flowchart in Figure
.
2. Refer to Table
for the corrective action.
