7.7 Error codes
If a recognized error occurs, this will be sent via IO-Link ISDU parameter 130 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.
Error
code
Hex
Fault
Possible cause
Solution
0x01 Internal EEPROM
error
Operating voltage was disconnected too
quickly after changing the parameters,
saving process was not complete
Reset to factory settings. Recording of
a valid data set via IO-Link
(with engineering tool)
0x02 Internal bus error
Internal bus was interrupted
Turn the power on again
0x03 Calibration error
Calibration was canceled when
measurement value was too high or too
low
Ventilate the vacuum circuit before
performing the calibration
0x05 Undervoltage U
A
Actuator supply voltage is too low
Check power supply and power load
0x07 Undervoltage U
S
Sensor supply voltage is too low
Check power supply and power load
0x08 IO-Link error
Connection to master interrupted
Check the connection line, power up
again
0x0F Overvoltage U
A
Actuator supply voltage is too high
Check power supply
0x11 Overvoltage U
S
Sensor supply voltage is too high
Check power supply
0x12 Supply pressure
System pressure outside the permitted
range
Check the supply pressure and
specified value
0x15 Measurement
range exceeded
The measurement range of at least one
ejector was exceeded.
Check the pressure and vacuum
sections of the system
