4.7.8 Suction / Pressure valve

The pump valves are ball valves that only work properly in a
vertical position. The condition of the valves has a deciding ef-
fect on the operating capability of the pump.
Valves must be exchanged as complete units.
When replacing the valves it is important to check the flow di-
rection (1).
ATTENTION!

4.7.9 Electronics (operating panel)

The electronics permit proportional volumetric dosing via ana-
logue signals 0/4 ... 20 mA or contact signals with the option of
dividing or duplicating the pulse.
An integrated LCD display (2) and three LED's (1) for warning
and fault display indicate the current status of the dosing pump.
A connection for flow monitoring or flow measurement as well
as an empty signal with pre-alarm and dry operation alarm are
installed as standard (see chapter „Electric supply").
