Conductivity measurement (extra equipment)
Conductivity is measured with equipment from 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 final rinse, independently
of the process control.
If the conductivity in the final rinse is higher that the preset value, the machine is emp -
tied and the final 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 µ S/ cm
Calibrating the conductivity equipment
See manual: Liquisys CLM 223, from Hauser.
The conductivity equipment is calibrated at the factory by specifying the exact cell con -
stant; see below.
7.1 Default
7.2
Default
7.3 Set SP1 Limit 15 µ S/ cm*
Set Hi= Max. contact
Rest default
*The user chooses the value during process validation.
7.4 Default
7.5
Set 20 µ S/ cm
Rest default
7.6 Default
7.7
Set cell constant as value in certificate 98.7%**
Rest default
** Take the figure from the certificate for the measuring cell.
