11.6 Setting options at service
level
The following chapter is only intended for certified
service staff. The password for reaching the service level
can be found in the additional information provided
with the unit.
CAREL is not liable for damages caused by incorrect
parameter settings at this level.
Notice:
The parameters have already been configured ex
works and may only be changed with the appropriate
expertise.
The contact configuration is preset in all submenus.
Do not change this carelessly! Otherwise there is a
risk of damage to the system.
11.6.1 Conductivity sensors
The CAREL RO units ROC 25-80 are equipped with one
conductivity sensor (permeate).
The ROL units (and ROC-140 with blending kit) are
equipped with two conductivity sensors. One sensor
measures the conductivity of the feed water (ROH/
MIX), the other sensor that of the permeate. Both
conductivity sensors are pre-calibrated ex works.
1 CAL. ROH- / MIX
2 CAL. PERMEATE
In the case of recalibration during maintenance, the
calibration can be carried out either with the a help
of a buffer solution with known conductivity, or with
a conductivity tester according to the principle of
comparative measurement.
Notice:
When selecting the calibration liquid (not included
in the scope of delivery), please note the selected
measuring range:
• Note that this conductivity measurement is not tempera-
ture-compensated.
• To achieve a high measuring precision it is therefore re-
commended that the calibration liquid (or the water sam-
ple for the comparison measurement) has approximately
the same conductivity and temperature as the permeate
to be measured.
