Solenoid-Diaphragm Dosing Pump MAGDOS LP Operating Instructions
BA-10231-02-V03
8.7.3 Diaphragm rupture sensor leak sensor
If a diaphragm ruptures, the dosing medium starts to leak. The leakage
is drained via the leakage opening.
As an option, the MAGDOS LP dosing pump is supplied with a leak
sensor in the diaphragm flange; in the case of a diaphragm rupture, the
sensor passes on a signal to the dosing pump and stops it. The system
shows a "Diaphragm rupture" message on the display and reports a
disturbance. The dosing pump cannot restart until you press
Start
.
You must first replace the diaphragm and clean dosing medium residue
from the diaphragm flange. There must be no conducting connection
between the two rings of the leak sensor.
The connecting cable of the leak sensor has an M12x1 male connector
that you connect to connection socket 5 (see „Connection socket 5“ on
page 30).
For an explanation of the icons, see “Set "Diaphragm rupture" menu
item” on page 35.

8.7.4 Contact Water Meter
The Contact Water Meter measures the throughflow in a pipe and sends
a pulse to the dosing pump, which then starts dosing. This means that
ideal proportional dosing is also possible with large throughflow fluctua-
tions.
The Contact Water Meter connects to connection socket 2 (see
„Connection socket 2“ on page 29).
You determine the ratio of throughflow and executed strokes of the
dosing pump in "Pulse input" mode, (see „Water meter“ on page 44).
