JUDO i-soft TGA 2
Intended use
Where the
water pressure is greater than
7 bar
, a pressure reducer must be installed
upstream
of the water softening system
(see fig. 2). If the operating pressure is great-
er than 7 bar, malfunctions can occur.
The optimum operating pressure for the wa-
ter softening system is between 3 bar and
5 bar. This is where it operates most eco-
nomically.
2.2
Indication of particular dan-
gers
2.2.1 Electrical devices/installations
Electrical devices/installations that are not
splash-proof and are located in the vicinity of
the water softening system may be dam-
aged by water that escapes during installa-
tion or in the event of incorrect use of the wa-
ter softening system. If the electrical devic-
es/installations are connected to the power
supply, it is also possible that a short-circuit
could occur. Should this occur there is a risk
of electric shocks to people. Therefore elec-
trical devices/furnishings and equipment in
the vicinity must be splashproof and/or com-
ply with the legal regulations for wet areas.
ATTENTION
(see chapter 1.2 “Safety instructions and
dangers due to non-observation”)
Caution when touching without the cover!
During operation, electronic components
can become hot. Also there is a danger due
to moving parts.
Potential-free output
Switching voltage............. maximum 24 V
Current ................................ maximum 1 A
(see chapter 5.8 “Potential-free signal re-
lay”)
Fig. 2:
Pressure reducer upstream of the sys-
tem
We recommend installation of a
pressure reducer for
water pres-
sures between 5 and 7 bar
.
No electrical cables and equipment
may be located below or in the im-
mediate vicinity of the water soften-
ing system!

In the power supply unit the mains
voltage is reduced to a safe low volt-
age of 24 V which is then used to op-
erate the system electronics. No oth-
er power supply units must be used.
Only low voltages can be used for
the remote transmission of the fault
indication via the potential-free out-
put!
