Fault
Cause
Measure
No compressed air supply
Check the compressed air supply
Vacuum level is not
reached or vacuum is built
up too slowly
Silencer is dirty
Clean the silencer
Leakage in hose line
Check hose connections
Leakage at the suction element
Check suction cup or sealing plate
Operating pressure too low
Increase operating pressure. Note the
maximum limits!
Internal diameter of hose line too
small
Observe recommendations for hose
diameter
Load cannot be held
Vacuum level too low
Increase the control range for the air saving
function
Suction force too low
Use larger area grippers or additional area
grippers
No display on the screen
ECO mode activated
Press any button or deactivate ECO mode
Faulty electrical connection
Check electrical connection and pin
assignment
Display shows error code

Warning message/IO-Link
warning message
“Leakage too high”
although handling cycle is
working optimally
Limit value -L- (permissible leakage
per second) set too low
Determine typical leakage values in a good
handling cycle and set as limit value
Limit values SP1 and rP1 for leakage
measurement set too low
Set limit values in such a way that there is a
clear differentiation between the neutral
and suction system states.
Warning message/IO-Link
warning message
“Leakage too high” does
not appear although there
is high leakage in the
system
Limit value -L- (permissible leakage
per second) set too high
Determine typical leakage values in a good
handling cycle and set as limit value
Limit values SP1 and rP1 for leakage
measurement set too high.
Set limit values in such a way that there is a
clear differentiation between the neutral
and suction system states.
We recommend always performing tests with original sample workpieces. We would be happy to
help you with testing.
