Conductivity measurement (extra equipment)

ConductivityismeasuredwithequipmentfromEndress+Hauser. (If the machine is

equippedwithamonitoringsystem,theconductivitymustbemeasuredasdescribed

under Conductivity measurement in Chapter 9.)

This may only be done by authorized personnel.

Function in washing process

Theconductivitymetermonitorsthequalityofthewaterinthenalrinse,independently

of the process control.

Iftheconductivityinthenalrinseishigherthatthepresetvalue,themachineisemp-

tiedandthenalrinseisrepeatedautomatically.

If, after three repetitions, the conductivity is still above the preset value, the process is

stopped and fault code 11 appears on the display.

Measuring range

The normal measuring range is 0-20 µS/ cm
