Table 4-1. Troubleshooting Chart (Continued)
POSSIBLE CAUSE
Blown Fuse.
Motor failure.
Reducer failure.
Auto-height photocell positioned
incorrectly.
Auto-height sensor has failed.
Wiring in the Auto-height sensor
circuit has failed.
SOLUTION
Locate carriage lift control fuse. Remove
fuse and check continuity.
Bad Fuse? Replace with correct type.
Perform motor test per motor manufac-
turer's recommendation.
Replace Motor as needed.
Remove Carriage Lift reducer-separate
motor from reducer. Rotate input shaft and
check for binding
Replace reducer as needed.
Check the position of the Auto-height
photocell. Make sure it is aimed at the
load. If the load is too short for the photo-
cell to see, the carriage will not move up-
this is normal.
Re-Aim the photocell correctly.
Check for 24VDC at the sensor. Check for
24VDC switching on the return wire to
PLC at the sensor.
No VDC Switching out at the sensor?
Replace sensor.
Run a continuity test on wiring from the
sensor to the PLC and 24VDC supply
rails.
No continuity on any wire?= repair or
replace wiring.
