Potential-free message
Filters identified “pot.free” and filters with
potential-free status relays can potential-
free transfer the following messages (see
fig. 8 and fig. 10):
–
Fault message
–
Message of backwash
The chapter “Notes on special dangers” and
the chapter “Installation” must always be
observed!
The maximum switching and switching
voltage must always be observed!
(see chapter “Notes on special dangers”).
In fig. 8 the contacts of the potential-free
relay are labelled in their power-off condi-
tion.
The relay can be connected as a break
contact or as a make contact.
If the filter power supply unit is plugged in
the relay changes 1 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 swich
to “Flushing”-state.
After a backwash, relay 2 will switch to “no
Flushing”-state.
5.8
Potential-free input
Filters identified “pot.free” and filters with
potential-free status relays have an addi-
tional input (potential-free input) and an
additional DIP-switch S2, which can be used
for control of the filter, if external switching
contacts are required (see tab. 2).
The chapter “Notes on special dangers” and
chapter “Installation” must always be
observed!
The mains adapter shall be un-
plugged from the socket for ac-
complishment of electric installa-
tion and for setting the DIP-switch!
