8. Remove the pulley and key from the motor shaft.
B. DRIVE MOTOR INSTALLATION
1. Place the drive motor in position and install the
four mounting bolts.
2. Place the pulley and key on the motor shaft.
NOTE
Do not tighten the pulley screws until after the belt
tension has been properly adjusted.
3. Install the belt and tighten the tension bolt.
4. Use a Burroughs Belt Tension Gauge to set the
tension for the drive belt. Set the belt tension to the
following:
E111: 30-40 lbs.
F111: 15-25 lbs.
5. Using a straightedge, align the drive motor pulley
with the gearbox pulley. Tighten the two allen
head screws.
6. Install wiring according to wiring diagram (located
behind header panel). Install electrical cover plate.
7. Install back and side panels.
A. CONTACTOR TESTS
The following tests will show if a contactor is working
properly.
1. Remove the header panel and visually check the
IntelliTec control board.
2. Check for a signal going to contactor. When the
spigot is opened or the Push To Freeze button is
pressed, the DRV LED on the control board will
light up. After three seconds, the CMP LED will
light up (Refer to Figure 6-4). If the LEDs do not
light up, refer to Section 7 Troubleshooting.
NOTE
In addition to the LEDs lighting, there will be an au-
dible click from the contactors and the motor and
compressor will start.
3. Check to ensure contactor is receiving signal.
Read voltage across the coils of the contactor
during a freezing cycle. Voltage should be about
115V. If there is no voltage reading, refer to
Section 7 Troubleshooting.
6.3 DRIVE MOTOR
The drive motor is used to rotate the auger assembly. An
internal, normally closed, centrifugal switch starts the
drive motor. The motor has an internal thermal overload.
A. DRIVE MOTOR REMOVAL
1. Disconnect machine from electrical supply before
removing any panels for servicing.
