1) The switch output is open and the current output adopts the configured alarm current. Errors concerning the switch output are not displayed
because the switch output is in a safe state.
2) If no remedial measures are taken, the warning messages are displayed following a device restart if configuration (span, switch points and offset)
is performed with a gauge pressure device and readings are > URL + 10 % or < LRL + 5 % and with an absolute pressure device and readings are >
URL + 10% or < LRL.

Behavior of the device in the event of a fault

The device displays warnings and faults via IO-Link. All the device warnings and faults are
for information purposes only and do not have a safety function. The errors diagnosed by
the device are displayed via IO-Link in accordance with NE 107. Depending on the
Event text Cause
A change in the span results
in a violation of the turn
down (max. TD 5:1)
Values for adjustment
(lower range value and
upper range value) are too
close together
Impedance of load
resistance at analog output
is too high
Load current too high
Switch output defective
The current is outside the
permitted range of 3.8 to
20.5 mA.
The pressure value is outside
the configured measuring
range (but may be within
the sensor range).
IO-Link communication no
longer available.
Diagnosis and troubleshooting
Remedial measure
• Operate device in the specified
measuring range
• Check the measuring range
• Check the cabling and load at the
current output.
• If the current output is not
required, switch it off via the
configuration.
• Connect current output with
load.
• If the current output is not
required, switch it off via the
configuration.
• Increase load resistance at
switch output
• Check output circuit
Replace device
Operate the device within the set
span
Manual restart is necessary
