Installation
SFC
5.
2 Release the four screws on the cover of the electronic module.
Caution!
There are connection cables between the cover and basic
housing.
3 Carefully remove the cover of the electronic module and leave
to hang on the strain relief.
Installation with
mounting rails
1 Fasten the mounting rail to the wall with two screws (diameter
5 mm) and two dowels (diameter 8 mm).
2 Hook the electronic module onto the mounting rail so that it is
flush at the right and fasten to the wall with two screws
(diameter 5 mm) and a dowel (diameter 8 mm).
3 Hook the flow block assembly onto the mounting rail on the left
next to the SFC and fasten to the wall with two screws
(diameter 5 mm) and two dowels (diameter 8 mm).
Refer to “Top-hat rail assembly” on page 121 and Page 123.
Please note
If the flow block assembly is not mounted directly next to the
electronic module, it can also be mounted without the mounting rail
(see next page).
Installation without
mounting rails
If the electronic module and the flow block assembly are to be
mounted in different places, the modules can be hooked onto
suitable tallow-drop screws by the top holding fixtures instead of
onto the mounting rail. Proceed with the installation as described
above.
Please note
If the electronic module and the flow block assembly are mounted
at separate locations, the sensor cable extensions with a
maximum length of 50 m must be used. An impedance converter
for the Redox, fluoride and pH sensors is also required (see 8.
“Complete Units, Retrofit Kits and Spare Parts”).
Refer to “Wall mounting assembly” on page 122 and Page 124.
Control cabinet installation
A special version is available for control cabinet installation. The
base unit (basic
electronics) of this version is attached to the
mounting plate using a top-hat rail. The front control panel is fitted
in accordance with the “Control cabinet
installation” assembly
drawing using the 3 m connecting cable provided (part no.
W3T161012).
Refer to “Control cabinet installation assembly” on page 125 and
Page 126.
