• Electric Divert Switch Removal Procedure

The ProSort is designed for easy removal of the divert switch assembly for maintenance or
replacement. In order to remove the electric switch assembly follow the following steps.
1. Turn off all power going into the panel connected to the divert that is needing to be removed. This
includes turning the disconnect on the front of the panel to the Off position and disconnecting the
3-Phase supply power and control power.
2. Wait at least 90 seconds after removing all power to allow the power to fully dissipate to a safe
level.
3. After waiting 90 seconds, remove the cover located on the side of the sorter under the divert
switch assembly by lifting and rotating down and out of the way. Next remove the orange power
cable and the green encoder cable from the servo motor mounted to the switch. Also remove the
5-wire m12 cable that is connected to the Smart Prox.
4. By reaching through the uncovered hole in the side channel, remove the two nuts at the back
side of the switch assembly channel. Then remove the two bolts on the outside of the sorter channel
which hold up the front side of the switch assembly channel (figure 11A).
5. The front side of the switch assembly channel may then be lowered and the entire assembly may
be removed through the opening in the sorter channel.

• Electric Switch Homing Procedure

1. Turn off all power going into the panel connected to the divert that is needing to be
homed. This includes turning the disconnect on the front of the panel to the Off position and
disconnecting the 3-Phase supply power and control power.
2. Wait at least 90 seconds after removing all power to allow the power to fully dissipate to
a safe level.
3. After waiting 90 seconds, remove the cover located on the side of the sorter under the
divert switch assembly by lifting and rotating down and out of the way. Next remove the
orange power cable and the green encoder cable from the servo motor mounted to the switch.
Also remove the 5-wire m12 cable that is connected to the Smart Prox.
4. By reaching through the uncovered hole in the side channel, remove the two nuts at the
back side of the switch assembly channel. Then remove the two bolts on the outside of the
sorter channel which hold up the front side of the switch assembly channel.
5. The front side of the switch assembly channel may then be lowered and the entire
assembly may be removed through the opening in the sorter channel.
6. Remove the nut on the bottom of the switch gate. After the nut is removed, pull the switch
gate out of the assembly. The servo motor shaft and cam should now be visible.
7. Connect the orange power cable and the green encoder cable.
8. Turn the cam by hand until the motor key is facing the outside mounting plate of the switch
assembly.
9. Turn the homing key on the servo drive enclosure on.
10. Apply power to the servo drive enclosure and allow for the drive to power up
completely.
11. Turn off power and remove the homing key.
12. If you reapply power at this point the cam should move to the home position. You can
reinstall the switch gate and check for correct position in both the home and diverted positions.
13. Turn off enclosure power and reinstall the electric switch assembly.

• Trouble Shooting

The following charts list possible problems that may occur in the operation of the ProSort.
TROUBLE SHOOTING DRIVES
TROUBLE

SOLUTION
1) Unblock jam eye.
2) determine cause of tripping: foreign debris, mislocated divert shoes, etc.,
and correct problem.
3) determine reason for rollers popping up and correct problem.
4) Adjust or replace proximity switch.
5) determine reason for low air pressure and correct problem.
6) Check power and wiring.
7) Refer to variable speed drive manufacturer's manual for trouble shooting.
8) Replace motor.
1) Refer to variable speed drive manufacturer's manual for trouble shooting.
1) Replace slat/shoe assembly.
2) Clean surface. (Refer to Preventive maintenance details)
3) Replace slat/shoe assembly.
4) Refer to divert Switch Checklist, Page 8 & 9.
1) Check air line and filter regulator. Replace if necessary.
2) Open lockout.
3) Replace.
4) See page 8 & 9 for proper adjust or replace.
1) Correct problem.
2) Trouble shoot control system.
1) Check 3-Phase power to the servo drive enclosure.
