Incorrect measurements

Trouble-shooting table

Table 6.2 summarises the most common operating errors which lead to incorrect
measurement by the Prolevel transmitter.

Sensor/
channel

Fault

Cause and remedy

Capacitance
Channel 1

Measured value wrong

•

Incorrect calibration? Check measured

value before linearisation, V0H9

- if not correct, check whether full and empty

calibration correct V0H1/V0H2

- If correct, check linearization parameters
- Check operating mode, V8H0

•

Change in product

- recalibrate for new product

•

Probe damaged, bent or pressed to side of

vessel

- check and remedy

•

Condensation in connection compartment

Deltapilot S
Channel 1

Measured value wrong

•

Incorrect calibration? Check measured

value before linearisation, V0H9

- if not correct, check whether full and empty

calibration correct V0H1/V0H2

- If correct, check linearization parameters
- Check operating mode, V8H0

•

Change in density of product

- recalibrate
- for Mode 0, 1, 5, enter new density at V8H7

•

Sensor damaged

- check and remedy

Capacitance
or Deltapilot S
Channel 1

Relays do not trip correctly

•

Incorrect settings, e.g. configured in wrong

units

- Check correct units used for all relay settings
- Check relay assignments, V1H4, V1H9
- Simulate settings in simulation mode - see

Section 6.3, if the relays LEDs switch, check
wiring

Capacitance
Channel 2

Does not switch correctly

•

Incorrect calibration?

- V1H7

≥

V8H6?

- change in product, build-up on probe

•

Build-up on probe

- wire electronic insert for build-up, see

Section 2.4

•

Settings wrong

- type of probe, fail-safe function, switching

delay

•

Probe damaged, bent or pressed to side of

wall

Liquiphant
Soliphant
Channel 2

Does not switch correctly

•

Build-up on probe

- clean regularly

•

Settings wrong

- type of probe, fail-safe function, switching

delay

•

Probe damaged or bent
