Installation Instructions
INSTALLING THE DRUM MOTOR:
The Drum Motor MUST be mounted horizontally, square to the conveyor
frame and parallel to the idler pulley. The arrow on the shaft opposite the
junction box MUST be pointing up,
with no more than 30 degrees off
of vertical. This will ensure that the
gear reducer is properly lubricated.
For special mounting arrangements,
consult your Van der Graaf (VDG)
representative.
NOTE: The Drum Motor has been factory filled with the correct amount
and type of oil, and does not require any additional oil.
ELECTRICAL CONNECTION:
To ensure proper electrical connection, always reference the connection
diagrams provided (see pages 4-8). Be sure to use qualified personnel and
observe compliance with local electrical codes. If in doubt, consult your
Van der Graaf representative. Ensure that the motor is being installed with
the appropriate overload protection device(s), (fuse, breakers, thermal
overload protection {GV-THERM}) if equipped. Reference the Drum Motor
nameplate to determine allowable full load amperage.
When the motor is equipped with a backstop (TB) device, the motor must
be connected electrically according to the correct rotational direction (see
page 9 for complete instructions).
PRIOR TO STARTING:
1. Be sure that the Drum Motor is correctly connected and supplied with
the rated voltage.
2. Check that the Drum Motor and conveyor belt are unobstructed and
free to rotate.
CAUTION: Never over tension the conveyor belt as internal damage
may occur.

Drum Motor with Sprockets (STM)
Assembly Procedure
1. Align pin slot in Sprocket (3) to the welded pins (2) on the shell (1).
2. Slide sprocket (3) over the Drum Motor shell (1).
3. Insert Set Screws (4) in their respective positions. Do not overtighten.
4. Repeat the sequence for the balance of the Sprockets.
5. Space Sprockets on the face of the shell to match belt pockets.
6. Lock center Sprocket/s by lightly tightening set screws.
IMPORTANT NOTE:
Overtightening of the set screws can result in the deformation
of the sprocket.
Ensure that locked Sprockets in head and tail pulleys are
corresponding to the same pockets in the belt.

Connecting a Drum Motor
Equipped with a Backstop (TB) Device
1. Look for the brass arrow on the end flange. It will indicate which direc-
tion the drum motor will rotate.
2. Mark the three incoming power supply leads with numbers L1, L2, L3.
Ensure that the ground lead is properly connected to the ground.
3. Connect the incoming power supply leads:
L1 to motor lead #1
L2 to motor lead #2
L3 to motor lead #3
4. Turn the power to the motor ON and OFF, (no more than 0.5 second on
the ON position). If the motor rotates then the connection is correct and
you can proceed to step 5. If the motor does not rotate, interchange any
of the two power supply leads.
Example: L1 to motor lead #2
L2 to motor lead #1
Turn the power ON and the motor should rotate in the correct direction.
Change the markings on the incoming power supply leads to correspond
with the motor leads.
Example: L2 to be changed to L1 and
L1 to be changed to L2.
Before Step 4 is complete, the motor should be running in the correct
rotation and the connection should be as follows:
Power supply Motor Leads
L1 to 1
L2 to 2
L3 to 3
When that is completed, proceed to step 5.
5. Finalize the motor connection:
Power supply Motor Leads
L1 to 1
L2 to 2
L3 to 3
6. Turn ON the motor.

Releasing & Engaging a Drum Motor
Equipped with a Manual Release Backstop (MRB) Device
NOTE: The drum motor is shipped with the Backstop device engaged.
To Release the Backstop Feature:
1. Bring the drum motor to full stop and disconnect power.
2. Remove the shaft cap located on the shaft end, opposite the junction
box or cable entry.
3. Using a 10mm deep socket 1/4” drive and a ratchet; insert socket into
the shaft and turn clockwise until the end, approximately 15 turns and
allow motor to rotate freely in opposite direction.
4. Remove socket and re-install the shaft cap.
The motor will operate in both directions.
To Engage the Backstop Feature - Repeat Steps 1 & 2:
3. Using a 10mm deep socket 1/4” drive and a ratchet; insert socket into
the shaft and turn counter clockwise, approximately 15 turns.
NOTE: Do not exert force to turn the socket as some movement for
the drum may be necessary to align the shaft to engage to its mating
part. Forcing the rotation of the socket may result in damage to inter-
nal components.
4. Once re-engaged, remove the socket and re-install the shaft cap.
The motor will operate in only the direction indicated by the brass
arrow mounted on the side of the unit.
