b.
Check for a shoe missing its pin or pin bearing. The slat and shoe may appear normal from the
conveying surface side.
c.
Inspect inside the sorter for any detached shoe pins or other debris.
d.
Depending on deceleration settings, a damaged slat will typically be on the top of the sorter, 10
to 30 feet downstream of the
“
missing bearing
”
sensor on the first divert switch.
If a slat with a missing component (shoe pin or bearing) is found, it is critical
to locate the missing component(s) and ensure all debris is removed from
inside the sorter before restarting. Shoe pins or bearings (or other large
solid debris) left inside the sorter can derail the chain and cause damage to
multiple slats, chains, and/or sprockets.
e.
Check for correct
“missing be
aring
”
sensor positioning relative to the switch pin sensor (4-
1/2”
upstream of the pin sensor) and clean the sensor window.
f.
Observe the sensor indicator light while the sorter is being manually turned or is running slowly,
to determine correct operation.
i.
The “m
issing bearing
”
sensor should turn on (triggered by the presence of the shoe pin
bearing) before the pin sensor turns on, and should turn off after the pin sensor turns off.
ii.
If a shoe pin without a bearing passes the “missing bearing” sensor, the “missing bearing”
sensor
should NOT turn on before the pin sensor turns on. The “missing bearing fault” will
be set whenever the pin sensor turns on and the “missing bearing” sensor is still off.
Monitoring internal components of the sorter with the drive running (even
at slow speeds) should only be performed by trained personnel who
understand the hazards of the conveyor in operation. The sorter drive must
be stopped and locked out before any mechanical adjustments are made.
7.
Discharge photoeye fault (jam detection)
a.
The sorter will stop if the discharge eye is continuously blocked.
b.
Clean and/or realign the eye if necessary, and clear any product jams.

Maintenance
7.1
Slat and shoe repair, replacement, and service
1.
See Figure 18 in Appendix 3 for an exploded view and part numbers
2.
Recommended to swap the complete slat with a spare, so the slat can be rebuilt without keeping
the sorter down for an extended period.
3.
See Section 5.1.6 for a description of how to swap out slats. Removal is the reverse of installation.
