Problem/remedy

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.

FAIL

Faulty low-flow or high-flow adjustment (e.g. the distance between
maximum and minimum flow is too small).

u

Repeat flow adjustment.

15 Maintenance, repair and disposal

Only the manufacturer is allowed to repair the unit.

u

Ensure that the sensor tip is free from build-up:

• Check the sensor tip for build-up one month after set-up.

• Repeat check regularly. Determine check intervals based on the application.

• In case of soiling clean the sensor tip with a soft cloth. Stubborn build-up, such

as lime, can be removed using a common vinegar cleaning agent.

u

After use dispose of the device in an environmentally friendly way in
accordance with the applicable national regulations.

16 Factory settings

The factory-set operating mode is REL.
