8.1 INTRODUCTION
This troubleshooting guide is intended to aid
service/maintenance personnel in isolating the
cause of a fault in a KC1000 Boiler. The trouble-
shooting procedures contained herein are
presented in tabular form on the following pages.
These tables are comprised of three columns
labeled: Fault Indication, Probable Cause and
Corrective Action. The numbered items in the
Probable Cause and Corrective Action columns
correspond to each other. For example,
Probable Cause No. 1 corresponds to Corrective
Action No. 1, etc.
NOTE:
The front panel of the C-More Control Box
contains an RS232 port which can be interfaced
to a laptop computer or other suitable device.
This RS232 communication feature permits
service personnel to view menu items and data
logs which can be useful in isolating faults. Refer
to Section 9 of this manual for detailed RS232
communication set-up and procedures.
