12 Troubleshooting

The unit has many self-diagnostic options. It monitors itself automatically during operation.

Warnings and error states are displayed even if the display is switched off. Error indications are also
available via IO-Link.

The status signals are classified according to NAMUR recommendation NE107.

If several diagnostic events occur simultaneously, only the diagnostic message of the event with the
highest priority is displayed.

If the measured temperature value fails, the process value for flow rate is still available.

Additional diagnostic functions are available via IO-Link

12.1 Error messages

Indication

Problem/remedy

Display off

Supply voltage too low.

u

Check the supply voltage.

Display switched off.

u

Check whether [diS] = OFF is set and change setting if necessary.

Err

Unit faulty / malfunction.

u

Replace the unit.

Measured value outside the detection zone.

• Flow value > 130% of the final value of the measuring range.

• Temperature value < -43 °C (< -46 °F) or > 133 °C (> 272 °F)

u

Check volumetric flow range / temperature range.

IOE.n

Malfunctioning. The unit is defective.

u

Replace the unit.

SC1

Switching status LED for OUT1 flashing: short circuit OUT1.

u

Check switching output OU1 for short circuit or excessive current.

SC2

Switching status LED for OUT2 flashing: short circuit OUT2.

u

Check switching output OUT2 for short circuit or excessive current.

SC

Switching status LEDs for OUT1 and OUT2 flashing: short circuit OUT1 and OUT2.

u

Check switching outputs OUT1 and OUT2 for short circuit or excessive current.

Loc

Setting keys on the unit locked, parameter change rejected.

u

Unlock the unit using the unit keys.

C.Loc

Setting buttons on the unit temporarily locked, parameter setting via IO-Link communication ac-
tive.

u

Finish parameter setting via IO-Link communication.

S.Loc

Setting keys locked via parameter setting software, parameter change rejected.

u

Unlock the unit via IO-Link interface using the parameter setting software.

PARA

Parameter setting outside the valid range.

u

Check parameter setting.

OL

Display range of volumetric flow or temperature exceeded:

• flow value between 120...130 % of the final value of the measuring range.

• temperature value between 122...133 °C (252...272 °F).

u

Check volumetric flow range / temperature range.

UL

Value below the minimum value of temperature display range:

• temperature value between -32...-43 °C (-26...-46 °F).

u

Check the temperature range.
