12 Warnings and Errors
12.1 Error Messages in SIO Operation
When a known error occurs, this is reported in the form of an error number. In SIO mode, error messages
are shown on the display. An “
E
” followed by the error number appears on the display.
The following table shows all the error codes:
Code dis-
played
Explanation
E01
Electronics error – internal data management, EEPROM
E02
Electronics error – internal communication
E03
Zero-point adjustment of the vacuum sensor outside ± 3% FS
E07
Supply voltage is too low
E08
IO-Link communication is interrupted
E12
Short circuit on output 2
E17
Supply voltage is too high
E18
Input pressure outside operating range
FFF
Present vacuum exceeds the measurement range
-FF
Overpressure in vacuum circuit; this normally happens exclusively in blow off mode.
Error codes in SIO mode
The error [E01] remains on the display after being shown once. Delete the error by switching off the
power supply. If this error occurs again after the power supply is switched back on, then the device must
be replaced.
12.2 Warnings and Error Messages in IO-Link Mode
In IO-Link mode, status information is available in addition to the error messages displayed in SIO mode.
The table below shows the IO-Link events:
Any condition monitoring events that occur during the suction cycle cause the system status light to im-
mediately switch from green to yellow. The specific event that caused this switch can be seen in the “Con-
dition monitoring” IO-Link parameter.
