7.13 Installing the sensors
7.13.1 Disinfection measuring cell
The DMZ3.1 measuring cell for measuring the degree of disinfection (free
chlorine) must be connected directly in the housing of the
TOPAX
®
MC
controller. The counter electrode is already installed in the fitting and con-
nected with the controller.
Pre-conditions for actions:
ü
The installation of the water sampling station, the electrics and the
hydraulics has been performed successfully.
ü
The measuring cells documentation is within easy reach.
Perform the following work steps:
1.
Unscrew the protective caps from the top of the valves and store
these away carefully for future use.
2.
Screw the measuring cells (Fig. 2 „Water sampling station EASYPRO
4“ on page 10, pos. 7) into the fittings. Observe the measuring cell
documentation during installation.
3.
Connect the measuring cells with the connecting cables.
ü
The disinfection measuring cell has been installed successful-
ly.
7.13.2 Measuring cells Redox value, pH value and
conductivity
The connecting cables are already installed on the
TOPAX
®
MC
controller
and need only be connected to the measuring cells.
Pre-conditions for actions:
ü
The installation of the water sampling station, the electrics and the
hydraulics has been performed successfully.
ü
The measuring cells documentation is within easy reach.
Perform the following work steps:
1.
Unscrew the protective caps from the top of the valves and store
these away carefully for future use.
2.
Screw the measuring cells (Fig. 2 „Water sampling station EASYPRO
4“ on page 10, Pos. 7 – 10) into the fittings. Observe the measur-
ing cell documentation during installation.
3.
Connect the measuring cells with the connecting cables.
ü
The measuring cells of the water sampling station have been
successfully installed.
7.13.3 Temperature sensor
The flow controller DFR 45 is fitted with a temperature sensor (Pt100)
which is already installed in the
TOPAX
®
MC
controller. This section de-
scribes how to replace the sensor.
Pre-conditions for actions:
ü
The installation of the water sampling station, the electrics and the
hydraulics has been performed successfully.
Perform the following work steps:
1.
Unscrew the sensor or the sealing plugs from the flow controller tem-
perature measuring station.
2.
Screw the new temperature sensor into the opening.
3.
Open the housing of the
TOPAX
®
MC
controller.
4.
Connect the connecting cable of the temperature sensor with the
clamps 57 and 58.
5.
Lead the connecting cable through one of the cable screw connec-
tions on the underside of the controller and screw it tight to guaran-
tee the protection class of the housing.
6.
Close the housing of the
TOPAX
®
MC
controller.
ü
The temperature sensor of the water sampling station has been
installed successfully.
