ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
Only original spare parts are to be used!
Arbitrary modifications and changes are
prohibited for safety reasons! They can
impair the function of the filter, lead to leaks
and as an extreme incident they can lead to
the bursting of the filter.
The imprinted test marks are only valid if
original spare parts are used.
Only the original power supply from
JUDO may be used!

Potential-free message
Filters identified “p-free” and filters with
potential-free signalling relays can transfer
in a potential-free mode the following
messages (see fig. 11 and fig. 15):
–
Fault message
–
Message to backwash
The chapter “Notes on special dangers” and
the chapter “Installation” have to be impera-
tively observed!
The maximum switching current and
switching voltage have to be imperatively
observed! (see chapter “Notes on special
dangers”).
In fig. 11 “Relay contact assignment” the
contacts of the potential-free relay are
marked in their currentless state.
The relay can be connected as a make
contact or as a breaker.
If the power supply unit of the filter is
plugged in the relay 1 changes its switched
condition!
If a fault message occurs the relay switches
to “Power-off or fault”-state.
At the start of a backwash, relay 2 will switch
to state “Flushing”.
After a backwash, relay 2 switches to the
state “no Flushing”.
The power supply unit has to be
unplugged from the socket for
accomplishment of electric instal-
lation and for setting the DIP-
switch!
