Type Description
BYTE Corresponds to Start-Stop switch; if Start-Stop = 0, then the pump is
stopped.
BYTE If the "Reset" value is switched from 1 to 0, the internal pump memory
is deleted (e.g. with batch metering) and - as far as possible - pending
errors are cleared.

UINT16 Dosing rate set in litres / hour ("Minimum" .. "Maximum dosing rate").
UINT16 Actual dosing rate in litres / hour (0.. "Maximum dosing rate").
UINT16 Maximum dosing rate in litres / hour
UINT32 Number of half revolutions in batch mode per trigger. (12 ... Maximum
= 999.999 litres / trigger).
BYTE If the value changes from 1 to 0, batch metering is activated in batch
operation. Batches can also be activated via the contact input.
BYTE If the batch memory is activated and a new batch is triggered during
batch metering already in progress, then the remaining revolutions are
increased by the number of the new batch.
If the memory is not activated, the remaining revolutions of the batch
not yet processed are cleared and the new batch is processed.
UINT32 The remaining revolutions still to be processed with batch metering
UINT16 Factor by which the incoming pulses are multiplied. The factor is given
as a hundredth. Value range is 2...19998 - the factor is then 0.01...
99.99 revolutions.
BYTE As with batch metering, once again here high factors are added
together or the remaining revolutions are cleared.
UINT16 Target direction of rotation 0 = clockwise and 1 = counter-clockwise
UINT32 Hose service life - revolutions since the last hose change

Name Description
Halt Pump is ready but not metering.
Manual Pump is metering continuously at
the set frequency.
Batch When triggered, the pump meters
the number of revolutions set in
batch pre-selection.
Contact Pump meters the number of revo‐
lutions calculated from the product
of "Number of triggers * External
factor".
Analog Pump meters according to the ana‐
logue signal and the
operating mode set on the pump.
