Proximity Sensor Replacement
Removal
Remove the ring gear cover and unscrew the quick-disconnect on the proximity sensor. Loosen the
two (2) lock nuts on the sensor and remove it.
Replacement
Position the sensor until the gap between the sensor head and the counter block on rotary arm is
approximately 1/8 of an inch. Tighten the lower locknut finger tight. Tighten the upper locknut and
reconnect proximity sensor. When all wires and guards (if applicable) have been replaced, turn on
the power and jog the rotary arm by using the arm jog switch. Then verify if the related input blinks.
WARNING!
Make sure that the power is disconnected and that a pad-lock is
installed on the main switch of the wrapper before you carry out these operations.
Motor Speed Control
Your Wulftec pallet wrap machine utilizes AC drives from Allen Bradley™, which are controlled by a
digital parameter unit. This unit is used to set the functions such as acceleration/deceleration time
and electronic thermal relay to allow variations in motor operation to best suit the specific
application and/or desired customer wrap parameters.
