Corrective Action:

Inspect the motor cable for any sign of damage. Check for burn marks at the plug. This could be caused by coolant contamination.

Measure the Ohms the across the motor power cable leads [1] at the plug. There should be resistance leg to leg. An open reading suggests a bad motor or cable.

Measure the Ohms on the motor power cable from each power leg to the ground leg [2] of the plug. This reading should be open.

If cable shows a short leg to ground at the plug, disconnect the power cable at the motor and check each motor power lead to the motor chassis [3]. If reading is open, the cable is at fault. If any lead tests short, the motor is motor is shorted.

Corrective Action:

Find the chip conveyor motor cable 140 at the I/O PCB. Press [CHIP FWD]. Use a multimeter with needle tip probes to measure the voltage between the black and red wires on the cable.

Have someone press and hold [CHIP REV]. Measure the voltage between the black and white wires. When the I/O PCB operates correctly, each voltage reading is 240 VAC.

If the voltage at the I/O PCB is correct, open the conveyor motor junction box. Use a multimeter with needle tip probes to check for voltage on the power leads at the motor.

If there is no voltage, check the motor and the cable. If there is voltage, check the capacitor. If you verify the voltage and capacitor are correct, inspect the motor drive shaft and keyway.

Corrective Action:

Check these fuses at the bottom right corner of the I/O PCB (Fuse type: AGC 5 amp):

• Single phase motors: FU2 [1] /FU3 [2]. There should be no fuse in FU4 [3].
• 3 phase motors: FU2 [1] /FU3 [2] /FU4 [3]

A short in the motor or the cable could have blown the fuse

Corrective Action:

Inspect the conveyor motor capacitor for damage. A damaged capacitor will usually have signs of deformation or bubbling on the capacitor casing. This could be caused by a short in the motor or in the cable.

Open the motor junction box. Check the capacitor. Look for burn marks on the case.

Measure the capacitor. Most multimeters can measure capacitance upon manual activation (turn to the correct units of measurement, and push the yellow button). It should be 6 or 9 microfarad as noted on the capacitor's case.

Corrective Action:

Inspect the conveyor belt for damage.

Corrective Action:

Make sure the belt tension is correct. Refer to the decals on the side of the machine. The correct belt slack for Jorgensen conveyors is 0.25" - 0.38" (6 - 10 mm). The correct belt slack for Hennig conveyors is 0.12" - 0.25" (3 - 6 mm).
