6. Additional connection o tions
6.1 Remote switching
The MV 876 B can be
remotely actuated by:
a) A volt-free switching circuit
(e.g. Bürkle type REL 2)
b) Via an open-collector output.
In both cases the minimium
holding period is one second.
Reverse rinsing occurs
when the inputs "Start" and
"U+" have been separated.
6.2 Remote monitoring
For remote monitoring of the
open/closed position of the
ball valve the installation of a
building management system
with O to 1 OV input is
recommended. The maximum
current is 10 mA. Wilh a
current of 0.5 V the ball valve
is open and with a value
between 5V and 6 V the ball
valve is closed.
6.3 Differential pressure swi_ ;:;. tc h ____
;;:..; ..;._
The reverse rinsing function
can be actuated according to
demand using the DOS 76
differential pressure switch
with voltage free switching. lt
is recommended !hat the
differential pressure be sei to
1.0 bar. Operation occurs
when the inputs "Start" and
"U+" have been separated, that is, after the
differential pressure has fallen below the sei
value. Through this it is guaranteed !hat a
maximum quantity of water is available for
reverse rinsing. lf reverse rinsing starts
immediately irrespective of the duralion of the
differential pressure signal, then the inputs
should be connected instead to "U+" and "SIGN"
&_
The DOS 76 differential pressure switch
can only be used where F 76 S fine filters
are also installed.
