Top Gripper

Actuator Error

GRIP OPEN

A command was given to

open or close the top

gripper actuator, and the

corresponding sensor did

not signal that the

complete move was

made within 5 sec.

Verify that there is no obstruction

preventing the gripper assembly

from closing.

Check to see that the pneumatic

cylinder sensor LEDs become

enabled when fully open and

closed. Adjust as necessary.

carrier is fully gripped and both left

and right part sensors are enabled.

One sensor is toggled on

or off.

Check to see that the sensor is not
