7 Troubleshooting
The error messages appear on the CobotPump display Warnings and errors are issued via the IO-Link. They are pro-
cessed and evaluated accordingly in the higher-level control.
The following table shows all of the error codes:
Code
Explanation
E01
Electronics error – internal data management, EEPROM
E03
Zero-point adjustment for vacuum sensor is outside of the tolerance
E05
Actuator voltage U
A
is too low or is not available at all
E07
Supply voltage U
S
is too low
E08
IO-Link communication error
E12
OUT
2
short circuit
E13
OUT
3
short circuit
E15
Actuator voltage U
A
is too high
E17
Supply voltage U
S
is too high
-FF
Overpressure in vacuum circuit
The error
E01
remains in the display after being shown once. Clear the error by restoring the factory setting with
the
rE5
function or parameter in the configuration menu. The configuration menu is accessed by pressing and
holding the menu button
in the output program level. If this error occurs again after the power supply is
switched back on, then the device must be replaced.
