Table 5.C – Module Troubleshooting

Problem or Trip Indicated Indication of the following conditions Possible Solutions

Contactor does not energize • Motor Protection activated

• Both Status LEDs ‘Off’

• Investigate and reset

• Check Control Power

• Loose connections in control circuit

• Verify IntelliVAC power input plug is in place and

properly seated

• Verify internal control fuse has not opened (Refer to

Figure 4.1 for location)

• Module Status LED ‘Red’ upon power up

• IntelliVAC faulted. Cycle control power to reset.

Replace IntelliVAC if unsuccessful.

• Module Status ‘Red Flash 1’ upon power up • Improper setting of dip switches. Check settings and

cycle control power.

• Loose connection in control circuit. • Verify contactor auxiliary set up. Reference Publication

1502-UM052_-EN-P (400A) or 1502-UM051_-EN-P

(800A) – Auxiliary Contact Set-up Procedure.

• Verify circuit continuity (is contactor plug connected

properly?)

Contactor closes momentarily and will not

reclose.

• Module status LED ‘Red’ (Series C) and Contactor

Status LED ‘Off’

• Module status LED ‘Yellow – Flashing’ and Contactor

Status LED ‘Off’ (Series D)

• Undervoltage fault (no TDUV), control voltage dipped

below trip point. Verify voltage levels are 110 to 240

VAC, 110 to 250VDC

Contactor fails to close.

•

Module status LED ‘Green’ and Contactor Status LED

‘Red Flash 1’ (Series C)

• Module status LED ‘Yellow-R1’ (Series D) and

Contactor Status LED ‘Off’

• Coil damaged or connections are loose. Repair and

cycle control power (Series C).

• Auxiliary Contact Assembly improperly adjusted.

Reference Publication 1502-UM052_-EN-P (400A) or

1502-UM051_-EN-P (800A) – Auxiliary Contact Set-up

Procedure. Cycle control power to reset (Series C).

• Armature Plate obstructed from closing to coil face.

Verify no foreign material behind the armature plate.

Cycle control power to reset.

• Both status LEDs ‘Off’ • Check internal control fuse. Verify IntelliVAC operation

in test mode before applying Medium Voltage. (Refer to

Fig. 4.1 for location.)

Refer to Table 5.A (Series C) or Table 5.B (Series D) for definition of Module

LED states.
