7.1 Cleaning

The exterior of the power source may be cleaned with a cloth dampened with a mild detergent

or

7.2 G

and wrung out. Disconnect mains power to the source before cleaning. Do not spray water
other cleaning agents directly on the power source.

eneral

This section describes the suggested maintenance and troubleshooting procedures. The

7.3 B

troubleshooting procedure is divided into two sections. The first section deals with basic
operation and connection of the equipment. The second section requires opening the unit and
using LED indicators and a simple multimeter to troubleshoot the unit down to the module level.
Only a qualified electronic technician should attempt this level troubleshooting.

asic operation

PARAGRAPH

PROBLEM

Excessive Output Voltage

Poor Output Voltage Regulation

Overload Light On

7.3.4 Distorted

Output

Unit Shuts Down After 1-2 Seconds

No Output and no lights on front panel

No output, but front panel controller is active.

Table 7-1: Basic Symptoms

7.3.1 Excessive Output Voltage

CAUSE

SOLUTION

External sense not connected (If used)

Connect external sense wires from TB2 on
rear panel to the AC power outlet TB1A
and TB1B

7.3.2 Poor Output Voltage Regulation

CAUSE

SOLUTION

Unit is overloaded

Remove overload

Unit is programmed to wrong voltage
range.

Select correct voltage range.

Input line has fallen below spec. limit.

Check input supply voltage.
