Problem
Cause
Correction
Conveyor does not move

If using the Press & Go menu recipes, wait until UI
displays the "Ready" status message
Coupling loose or disconnected
Tighten set screw on coupling
Belt link loose or disconnected
Replace belt link
Conveyor has stretched from use

Menu
Faulty IO board and/or built-in motor drive
Check for 24VDC input on black (-V) and red (+V)
wires
Check wires are connected properly
Inspect IO board for damage and replace if needed
Faulty stepper drive (STR8)
Check LEDs to identify alarm codes. Faults disable
the motor and can be cleared by cycling power to
the drive.
Try the built-in self test. Anytime switch 8 is moved
to the ON position, the drive will automatically
rotate the motor back and forth, two turns in each
direction. This feature can be used to confirm the
motor is correctly wired, selected and operational.
Check for 24VDC input on black (-V) and red (+V)
wires
Check wires are connected properly
Inspect stepper motor drive for damage and replace
if needed
