Operating instructions
4.2 Design and function
Chlorine gas dosing systems in a water treatment system must be
permanently ready for operation so that the water can be sufficiently
disinfected at any point. This explains the fitting of the systems with two
supply batteries - one side in operation, the other on stand-by. The
vacuum chlorine changeover valve effects automatic switching between
the two cylinders or drum batteries.
Typical installations are shown on the example installations (from page
20).

Structure of the device
If the power supply from the operation battery ebbs, the vacuum
generated by the injector will become stronger. The control
a
recognises
the chlorine shortage using the contact gauge
b
and activates the motor
c
on the three-way ball valve
d
.
The control signals the operating state with coloured LEDs in the flow
chart. (See section 8 „Control“ on page 22) The most important
operating signals are available for remote indication as relay contacts.
The "residue discharge" function enables the consumption of residue
from incompletely-emptied tanks of a total vacuum battery. Working in
set intervals, the changeover unit then switches to the battery registered
as empty and removes the residue.
Manual changeover can be triggered by the push of a button. Mechanical
changeover by hand is possible given a power outage.
