F. Remove the metal covers and circuit boards from the top of the cross
arm housing.
G. Disconnect necessary cabling. Make note of orientation for reassembly.
3. Disconnect cabling from the Power/Signal Distribution PCB or Column I/O
PCB and remove the PCB from the side of the Cross Arm Housing.
4. Remove the tie wraps securing the cabling to the side of the Cross Arm
Housing.
NOTE: It is necessary to remove the snap rings from the top rear roller
bearing and move the bearing from side to side to access 2 of the
hex bolts in the next step.
CAUTION: Ensure that the cross arm is fully retracted while removing the 4 hex
bolts that secure the Control Panel Housing to the Vertical Column
Flange. The L-arm Driver Assembly weighs approximately 60 lbs and
the weight is not balanced on the flange.
5. Remove 4 hex bolts securing the Control Panel Housing to the Vertical
Column Flange.
6. Remove the Cross Arm Housing and L-arm Driver Assembly and place the
assembly on it's side.
7. Remove the two Torx head screws securing the round metal flange in the
bottom of the Cross Arm shaft and remove the round metal flange.
8. Disconnect the wires from the TB1 Terminal block on the L-arm Motor
Power PCB. Refer to the Interconnect Schematic when rewiring.
9. Pull the robot cable through the Cross Arm shaft.
10. Disconnect the limit switches by removing 2 allen head screws from each
limit switch.
NOTE: Pull the motor away from the rubber motor mount as you are
backing out the flat head screws. This will increase the space
required for the allen ball drivers.
11. Remove 4 flat head bolts securing the L-arm Rotation Motor to the L-arm
gear box and remove the L-arm Rotation Motor, Limit Switches, and metal
bracket as an assembly.
NOTE: Use Loctite 222 when reassembling.
