Voltage
Fuses
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
