Diagnostics and troubleshooting
10.1 Troubleshooting
If an illegal configuration exists in the device, the device switches to the failsafe mode.
Example:
• The diagnostic message "C485" is displayed via IO-Link.
• The device is in the simulation mode.
• If the device configuration is corrected, e.g. by resetting the device, the device quits the
fault state and switches to the measuring mode.
General errors
Problem
Possible cause
Remedy
Device does not respond Supply voltage does not match that specified on
the nameplate.
Apply correct voltage.
Supply voltage has incorrect polarity.
Reverse polarity of supply
voltage.
Connecting cables are not in contact with the
terminals.
Check for electrical contact
between cables and correct.
No display
The local display might be switched off.
Switch on the local display (see
the "DOF" parameter
description).
Device measures
incorrectly.
Configuration error.
Check and correct the
parameter configuration.
No communication
• Communication cable not connected.
• Communication cable incorrectly attached to
device.
• Communication cable incorrectly attached to
the IO-Link master.
Check wiring and cables.
Output current
≤ 3.6 mA
Signal line is not wired correctly.
Check wiring.
No transmission of
process data
There is an error in the device.
Correct errors that are displayed
as a diagnostic event→ 46.
Parameter plausibility
check has failed (IO-Link
message as per IO-Link
standard)
An IO-DD with corresponding default values is
used for all pressure measuring ranges. This IO-
DD applies for all measuring ranges! The default
values of this IO-DD can be inadmissible for this
device. IO-Link messages (e.g. "Parameter value
above limit") may be displayed when the device is
updated with these default values. Existing values
are not accepted in this case. The default values
apply exclusively to the 10 bar (150 psi) sensor.
The data must first be read out
of the device before default
values are written from the IO-
DD to the device.
