Solution
Warning message/IO-
Link warning message
"Leakage too high" al-
though handling cycle
is working optimally
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.

12.2 Error Codes, Causes and Solutions
The condition monitoring functions output events that can be used to draw conclusions with regard to
the process. If a known error occurs, it is transmitted via the IO-Link ISDU parameter [0x0082] in the form
of an error number.
The system status is automatically refreshed on the NFC tag every 5 minutes at the latest. That means that
an error may be displayed via NFC even though it has already disappeared.

Fault
Possible cause
Solution
E01
Internal error
Electronics
Operating voltage was dis-
connected too quickly after a
parameter change, saving
process was not complete
1. Clear the error by restoring the
factory setting with the [
rE5
]
function or parameter.
2. Use engineering tool to import a
valid dataset.
3. If error [
E01
] occurs again after
restarting the supply voltages:
Replacement by Schmalz re-
quired
E03
Zero-point error/
calibration error
on vacuum sensor
Zero-point adjustment for
vacuum sensor is outside of
the tolerance 3% FS. Calibra-
tion was canceled when
measurement value was too
high or too low.
1. Ventilate the vacuum circuit.
2. Perform calibration.
E07
Undervoltage U
S
Sensor supply voltage is too
low.
1. Check power supply unit and
power load
2. Increase supply voltage
E08
IO-Link error
Connection to master inter-
rupted.
1. Check connection line.
2. Repeat the power up process.
E17
Overvoltage U
S
Sensor supply voltage is too
high.
1. Check power supply unit.
2. Reduce supply voltage
FFF
Vacuum range
Measured vacuum level too
high, sensor defective
1. Check and adjust supply pres-
sure.
