5.12 Test Procedures

A. Main Contactor (W1) Test

1. Check continuity between:

L1 to T1

L2 to T2

L3 to T3

L4 to T4

The contacts should be open – no continuity.

Actuator Arm

Cover Screws

Art # A-08157_AB

Input

Side

CutMaster 52 & 82

W1 contactor wired for 1PH

Main Contactor

Jumpers

Actuator Button

2. Retest continuity between terminals while engag-

ing the contacts manually. This can be done by

pushing down on the recessed actuator button on

the top of W1 or pushing down on the actuator

arm on the side of W1.

L1 to T1

L2 to T2

L3 to T3

L4 to T4

The contacts should be closed – Continuity

3. Visually check W1 contact points. To take the

cover OFF, remove the two cover screws shown

in the previous illustration. Replace if contacts

are stuck together or show excessive arcing

B. Input Diode Module Test

1. Using an ohmmeter perform the tests in the

chart

If the test reveals a failed component, replace

Main PCB and perform main contactor test – Sec-

tion 5.11-A

C. Input Capacitor PCB Test

1. Using an ohmmeter check continuity between the

following points:

Input Capacitors

Meter +

Meter -

Charging

Most meters will show a charging action. Initially a

low resistance will be shown and then the resistance

will start to increase. If the meter probes are reversed

the reading will decrease to zero, then start charging

in the opposite polarity.

2. If a short is found replace Capacitor PCB assem-

bly.

3. Check continuity between the following points

Input relays
