Troubleshooting/Service

If the symptom still persists, refer to the installation section in this manual to ensure proper installation and proper use of the controller in your system.

7.7 Troubleshooting Procedures

Introduction

The troubleshooting procedures are listed in numerical order as they appear in Table 7-4.Each procedure lists what to do if you have that particular failure and how to do it or where to find the data needed to accomplish the task.

WARNING—SHOCK HAZARD

TROUBLESHOOTING MAY REQUIRE ACCESS TO HAZARDOUS LIVE

CIRCUITS, AND SHOULD ONLY BE PERFORMED BY QUALIFIED SERVICE

PERSONNEL. MORE THAN ONE SWITCH MAY BE REQUIRED TO DE-

ENERGIZE UNIT BEFORE SERVICING.

Equipment needed

You will need the following equipment in order to troubleshoot the symptoms listed in the tables that follow:

•Multimeter – Capable of measuring millivolts, milliamps and resistance.

•Calibration sources – T/C, mV, Volt, etc.
