10.1   Help with Malfunctions

Malfunction

Possible cause

Solution

Power supply disrupted

Electrical connector

4

Make sure device is properly con-
nected to power

No communication

Incorrect electrical connection

4

Check electrical connection and pin
assignment

Higher-level controller not cor-
rectly configured

4

Check the controller configuration

Ejector does not re-
spond

No power supply

4

Check electrical connection and pin
assignment

No compressed air supply

4

Check the compressed air supply

Vacuum level is not
reached or vacuum is
built up too slowly

Silencer is dirty

4

Replace the silencer

Leakage in hose line

4

Check hose connections

Leakage at suction cup

4

Check suction cup

Operating pressure too low

4

Increase operating pressure. Note
the maximum limits!

Internal diameter of hose line too
small

4

Observe recommendations for hose
diameter

Load cannot be held

Vacuum level too low

4

Increase the control range for the
air saving function

Suction cup too small

4

Select a larger suction cup

No display on the
screen

Faulty electrical connection

4

Check electrical connection and pin
assignment

Display shows error
code

See "Error codes" table

4

See "Error Codes" table in the fol-
lowing chapter

Warning message
“Leakage too high”
even though handling
cycle is working opti-
mally

Limit value -L- (permissible leak-
age per second) set too low

4

Determine typical leakage values in
a good handling cycle and set as
limit value

Limit values SP1 and rP1 for leak-
age measurement set too low

4

Set limit values in such a way that
there is a clear differentiation be-
tween the neutral and suction sys-
tem states.

Warning message
“Leakage too high”
does not appear al-
though there is high
leakage in the system

Limit value -L- (permissible leak-
age per second) set too high

4

Determine typical leakage values in
a good handling cycle and set as
limit value

Limit values SP1 and rP1 for leak-
age measurement set too high.

4

Set limit values in such a way that
there is a clear differentiation be-
tween the neutral and suction sys-
tem states.
