5.24 Dosing monitoring
The pump incorporates a dosing monitoring input (see connection overview in fig.
Fig. 24
The pump can be fitted with a dosing monitor, which
detects ineffective dosing strokes.
The dosing monitor is designed to monitor the dosing
of liquids which may cause gas accumulation in the
dosing head, thus stopping the dosing process even
if the pump is still operating.
During the dosing process, the dosing monitor gives
pulse signals to the monitor input so that the pump
can compare performed dosing strokes (from internal
stroke sensor) with externally measured physical
strokes (from the dosing monitor). If an external
dosing stroke is not measured as a result of the
internal dosing stroke, this is considered a fault that
may have been provoked by empty tank or gas in the
dosing head.
The dosing monitor should be connected to the input
for dosing monitoring. This input must be configured
for dosing monitoring. Once the input has been set to
dosing monitoring and a dosing monitor has been
connected and set, the dosing monitoring function
will be active.
