Commissioning
WARNING
Risk of injury due to falling loads.
• Before exhausting remove the payload.
1. Slowly pressurise gripper.
2. Set the opening and closing time with an upstream one-way flow control
valve: screw in the flow control screw completely and then unscrew it one
turn.
3. Perform a test run without payload.
Check the following:
–
Allocation of the supply ports
–
The reliable function of the proximity switches (if installed)
–
Stop noise of the piston: the piston stop must be soft, that means not
audibly hard or metallic.
Piston stop
Insight/conclusion
soft
The gripper speed is correct or can be increased. With
upstream one-way flow control valve: unscrew the flow control
screw slightly.
è
The gripper speed increases.
hard/metallic
The gripper speed is too high. With an upstream one-way flow
control valve: screw in the flow control screw until the piston
stop is no longer audibly hard or metallic.
è
The gripper
speed is reduced.
4. Perform a test run with payload.
Ä
The gripper must hold the payload securely.
5. After successful test runs:
–
Remove the payload or lock to prevent it from falling.
–
Exhaust the gripper.

Malfunctions
9.1
Fault clearance
Error description
Cause
Remedy
Gripper does not hold payload
securely.
Insufficient operating pressure.
Increase the operating pres-
sure. Observe the max. permis-
sible value.
The pressure point of the
gripper fingers is too far out-
wards.
Move the pressure point
inwards.
The payload is too heavy.
Select a larger gripper.
Gripping only with return spring
force with incorrect gripping
direction.
Use the intended gripping
direction.
The gripper does not open/
close.
No compressed air.
Check the supply ports.
The gripper is faulty.
Replace the faulty parts
The proximity switch does not
indicate the gripper status.
The proximity switch is incor-
rectly adjusted.
Check and adjust the posi-
tion of the proximity switch
The connecting cable is discon-
nected.
Replace the connecting cable or
proximity switch

Disassembly
WARNING
Risk of injury due to unexpected movement of the gripper fingers or falling
payload.
• Before exhausting: remove the payload at the gripper.
• Disconnect gripper from the compressed air supply.
1. Disconnect the gripper from the compressed air supply.
2. Remove the supply ports and retaining screws.
