Troubleshooting list

Error

Diagnosis

Remedy

Power supply missing

Connect or switch on power supply

Sensor does not work or no

display or no output signal

Device fuse defective

Check device fuse and replace if necessary
(see Changing fuses (Page 61))

Reflections in the glass

Clean glass

Transmitter does not react

to controls

Glass is not tight to the operating unit

Screw in the electronic cover tightly

Personal code is activated

Enter personal code (menu 6.1 or deactivate by

entering 0 in menu 6.2)

Transmitter cannot be

parameterized by the

operating module

Local operation lock activated by HART or

PROFIBUS

Cancel operation lock

Ambient temperature outside permissible

range

Remote design: bring transmitter into a

temperature range of 0 to 50 °C

Output signal OK but no

display visible

Display defective

Change operating module

Low flow cut-off set too high

Reduce low flow cut (menu 3.1.6)

Flow opposite to preferable direction at

setting of measuring direction to "forwards

only"

Switch over preferred direction menu (3.1.5.1)

or set measuring direction to "forw.+rev." (menu

3.1.5.2)

Measured value set to 0 via digital input

Switch over signal at digital input (menu 4.3.2)

or switch off function (menu 3.3.1)

Cable connection to sensor defective

(only for remote design)

Check cable connection and exchange as

required

Flow display = 0 at available

flow

SmartPLUG defective

Have SmartPLUG exchanged (only by service

personnel)

Hydraulic zero point drift, application-

dependent

Perform zero correction (menu 6.6.2) or enter

correction value directly (menu 6.6.1)

Transmitter indicates flow at

zero flow

Earthing problems

Provide potential equalization (see Potential

equalization of sensor (refence potential)

(Page 18))

Air, gas occlusions

Eliminate gas occlusions or use gas trap

Earthing problems

Provide potential equalization (see Potential

equalization of sensor (refence potential)

(Page 18))

Vibrations in the sensor and/or in the

cable run

Fix the sensor better, strap cables

Medium conductivity too low

Check conductivity; measuring method may be

unsuitable

Proportion of solids too high

Reduce proportion of solids, measuring method

may be unsuitable

Fluctuating measuring

results at constant flow

Very unstable measurement, strongly

fluctuating values, output going towards

zero

Check for moisture in SmartPlug

If fitted with round SmartPlug call factory

product support

Inlet and outlet lines insufficient

Change installation (see Sensor installation

(Page 14))

Measuring deviations,

measuring errors

Highly turbulent flow profile

Change inlet line, use flow rectifier, reduce

diameter of tube
