Repairing After Collisions

Overview

Components of the actuator may be damaged or destroyed as a result of a collision.

NOTE: After a collision, inspect the actuator unit for obvious damages. Verify that the actuator is running smoothly.

WARNING

FALLING OR EJECTED PARTS

oThoroughly inspect all components of the actuator and all components attached to the actuator, including the motor and the belt drive (if installed), for damage after a collision.

oDo not use the actuator if any of the components are damaged or suspected to be damaged.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Verifying the Components

Step	Action
1	Verify the components for completeness. If any components are missing, locate the same and remove them from the surrounding machinery.
2	Replace damaged or missing components.

NOTE: In case of any suspect on mechanical damage or doubt, contact your local Schneider Electric service representative.

Verifying the Toothed Belt in the Belt Drive (Optional Equipment)

Step	Action
1	Remove the cover of the belt drive. For further information, refer to Unimotion Maintenance- and Assembly Instructions PNCE Electric Cylinder.
2	Verify the toothed belt by a visual inspection for damaged teeth and abrasion. To perform a visual inspection, maybe it is necessary to remove the toothed belt.

Step

Action

Remove the cover of the belt drive.

For further information, refer to Unimotion Maintenance- and Assembly Instructions PNCE Electric Cylinder.

Verify the toothed belt by a visual inspection for damaged teeth and abrasion. To perform a visual inspection, maybe it is necessary to remove the toothed belt.

NOTE: A damaged toothed belt must be replaced.

Verifying the Piston Rod (Optional Equipment)

Step	Action
1	Inspect the piston rod for backlash. If the piston rod has backlash, it is appreciably worn.
2	Remove the motor.
3	Manually move the piston rod and inspect for irregular noise or vibration. Irregular noise or vibration indicates a damage of the piston rod. Damage causes rapid wear.

NOTE: A worn-out or damaged piston rod must be replaced. Contact your local Schneider Electric service representative.

Verifying the Elastomer Coupling or Clamping Set (Optional Equipment)

Step	Action
1	Remove the motor.
2	Verify the elastomer coupling or the clamping set by a visual inspection for damage.

NOTE: A damaged elastomer coupling must be replaced.
