ERROR 01: sensing probe is not detected
Cause:
the sensing probe is not connect or is defect
Effect:
the display indicates "0" for all measurand. The analogue output defaults to the lowest
configured value.
Action:
check the head of the sensing probe for visual damage.
check the sensor cable from the sensing probe to the electronics of the signal conditioning.
ERROR 02: the EEprom is defect
Cause:
the EEPROM for the storing of the consumption counter and MIN /MAX value is defect.

MAINTENANCE
7.1.
Removal of the sensing probe of the MultiController
MultiController without hot tap valve
Make sure that the pipe line is depressurized!
•
Loose the retainer nut and pull the sensor probe from the MultiController.
•
Operation without the flowmeter installed page 10.
7.2.
Removal of the sensing probe of the hot tap valve
The sensor can be removed under pressure without flow interruption.
•
Turn the hot tap valve with the hand without tools (anti-clockwise rotation) in the position SERVICE
- CLOSE.
•
Only if the hot tap valve is fully in the position SERVICE - CLOSE the sensor is hermetically sealed
against the pressurized line.
•
Loose the retainer nut slowly. Let the air exhaust slowly and make sure that is was only the relief
pressure and the hot tap valve is hermetically sealed.
•
Loose the retainer nut and pull the sensor probe from the hot tap valve.
•
Operation without the flowmeter installed page 10.
The sensor head is sensitive. Use the protection cap for transport and storage!
7.3.
Cleaning of the sensor of the flowmeter
Do not use an abrasive cleaning agent, an organic solvent containing halogen or acetone.
•
Clean the head of the sensor probe by carefully swirling in warm water of isopropyl alcohol. It is
recommended to use isopropyl alcohol if the pollution is crease or oil.
The sensor should not be touch by fingers or solid objects like screwdrivers or brushes!
•
Leave the sensor to dry in ambient air.
