S&C Scada-Mate@ Switching Systems Troubleshooting Guide Outdoor Distribution I I INTRODUCTION I
1 e The equipment covered by this publication must be operated and maintained by qualified persons who are thoroughly trained and who understand any hazards that may be involved. This publication is written only for such qualified persons and is not intended to be a substitute for adequate training and experience in safety procedures for this type of equipment.
1
The publication provides a troubleshooting guide for diagnosing operat,ing problems experienced with an S&C Scada-Mate Switching System. This guide is primarily intended for installations furnished with a communication and control unit that includes a WESDAC DART (Distribu- tion Automation Remot,e Terminal) RTU by Harris Con- trols, but, is also generally applicable to installations furnished with a remote terminal unit of other manufac- ture, as well as installations furnished with a switch-con- trol unit or a switch-control unit with battery charger and battery packs.
The DART RTI; and optional communication proces- sor module (CPM), if furnished, must be properly config- ured at the time of installation.
Instructions for configuring the DART RTU are pro- vided in Instruction Sheet 768-550. “S&C Scada-Mate Switching Systems: Communication and Control ITnit Fur- nished With DART RTU C,onfiguration System Software Version 2.02 or Higher.”
Instructions for configuring the CPM using the DBO/CPM Configuration System are provided in Instruc- tion Sheet 768-600, “S&C Scada-Mate Switching Systems: Communication Processor Module for Communication and Control Unit;” refer also to Harris Controls’ documen- tat,ion, “CPM Configuration Guide” and “DART Configura- tion Syst,enl User’s Guide.” Instructions for configuring the CPM using the ConfigPro Configuration System are provided in Harris Controls’ documentation, “ConfigPro Configuration System User’s Guide.”
In the troubleshooting procedures that follow, it is assumed that the user has a good working knowledge of the DARTMAINT maintenance program and, if the optional CPM has been furnished, the WESMAINT maink- nance program.

INTRODUCTION - Continued I Where to Start . . . Refer to the table of contents on page 1 to determine the appropriate chart for diagnosing the problem. Refer to the illustrations in Instruction Sheets 768-550 and 768-555 to identify components indicated in the chart.
Instructions for replacing firmware and components of a communication and control unit are provided in Instruc- tion Sheet 768-555. As that instruction sheet points out, during the replacement procedure, precautions should be taken to prevent static charges, which can damage not only the existing item but the replacement item as well. Although replacement items are furnished in static- shielded bags, the use of a static-dissipative work surface, such as the 3M 8501 Portable Static-Dissipative Field Ser- vice Kit (available from S&C as Catalog Number 9931- 218), is highly recommended. This kit includes a static- dissipative work mat and a ground cord assembly with wrist strap, for connecting the mat-along with the person changing the item-to the same ground point.
If, after following the diagnostic procedure, you still can’t resolve the problem, or if the problem is intermittent in nature, contact the nearest S&C Sales Office.
