e.
Sorter operating speed and other settings should generally be changed through the HMI, not
directly on the VFD. Do not change settings directly on the VFD unless directed to by Bastian
personnel or qualified Controls technicians.

Troubleshooting Faults
Always determine and correct the cause of a fault before restarting the
machine. In the case of a component failure, ensure all missing pieces are
located and any debris is removed from the inside of the sorter before
restarting. Failure to fully correct the fault before continued operation can
cause damage to the sorter internal components.
1.
Fault troubleshooting details depend on the exact HMI implementation. This section is intended to
serve as a general guide for all ZiPline shoe sorters.
2.
Sorter stop
—
tripped sensor gate (internal or underneath)
a.
If a sensor gate trips, it will require manual reset of the gate mechanism before the sorter can
be restarted.
b.
A tripped sensor gate is an indication of debris present inside the sorter, or a damaged or
missing slat.
3.
Catenary photoeye fault (sorter stop)
a.
Only the lower catenary eye will cause a sorter stop. If the lower eye is blocked by the slats in
the catenary when the catenary is at rest or in a steady-state running position, the chain must
be shortened before operating the sorter to avoid damage to slats and possible derailment of
the chain.
b.
The upper catenary eye provides an advance warning so maintenance can be scheduled.
c.
If the catenary eye is not blocked, check for dirt on the sensor or reflector, or check for debris
that may have blocked it temporarily.
d.
Catenary sag will increase temporarily during sorter startup. If this is causing catenary photoeye
faults during sorter start, it may be necessary to reduce the startup acceleration of the sorter
drive motor.
4.
Tail discharge photoeye fault (sorter stop)
a.
Check for missing slats or debris.
b.
Depending on deceleration settings, a damaged or missing slat would typically end up 10 to 30
feet downstream of the tail section.
c.
Debris or a broken slat may be inside the tail section.
d.
Check the photoeye alignment and clean the sensor and reflector
5.
Discharge prox fault (sorter stop)
a.
Check for a missing or damaged slat or shoe.
b.
Depending on deceleration settings, a damaged slat will typically be on the bottom of the sorter,
10 to 30 feet upstream of the drive section.
c.
Check for debris or a package stuck inside the drive section.
6.
“
Missing bearing
”
fault (sorter stop)
a.
Check for a missing or damaged slat or shoe.
