To change the drive motor, please proceed as follows:
  1. Disconnect the electrical and pneumatic supply of the entire conveyor system and secure against reconnection.
  2. Remove the clear front cover of the drive station and release the chain tensioner. Lock it in that position with an adequate device.
  3. Remove the chain from the drive sprocket.
  4. If the drive sprocket has more than 18 teeth, please remove it from the motor shaft as described in the previous chapter "Replacing the re-directional sprocket". For smaller sprockets, the sprocket can remain on the output shaft.
  5. Release the motor clamping bolts and remove the motor backwards.
  6. If the drive sprocket is still installed, please mount it to the new motor according to the procedure of replacing the drive sprocket.
  7. Install the new motor and the drive sprocket, if required, in the reverse order as described. Make sure the drive sprocket is in the correct position: The centerline of the chain has to be in one line.
  8. Re-tension the chain and reset the chain tensioner.
  9. Reinstall the clear front cover.
  10. Run the conveyor system and check the tension of the chain at the chain tensioner. If the tensioner is almost at its far end, the chain has to be shortened by another chain link.
  11. Check the chain tension after two hours of operation again.
