9.3.3 Replacement
Driver: First turn off the power then remove the two sets of wires and two DC +24V power
supply cables from the Driver. There is a screw at the top and bottom of the driver.
Remove the screws to install the new Driver. Once replacement is complete, reconnect
the wiring and power cables. After replacement re-adjust the driver using the proper
adjustment method.
Conveyor Motor: On top of the conveyor motor there is a clamped screw. Use a hex key
wrench to remove it, then insert the hex key wrench inside to unfasten the screw. Once
the screw is loosened the axle can be removed. Now unfasten the four screws around
the motor and remove the wire linking it to the machine. The motor can now be removed.
