This operating mode provides the option of working with large
transfer factors (up to 99,999). Metering can be triggered either by
pressing the
[Clickwheel]
or by a pulse received via the "External
control" terminal by a contact or a semiconductor switching ele‐
ment. It is possible to pre-select a metering volume (batch) or a
number of strokes using the
[Clickwheel]
in the
‘Settings’
menu.
The capacity and/or stroke rate is controlled by an analogue cur‐
rent signal via the "External control" terminal. Processing of the
current signal can be preselected using the control unit.
6.6 Functions
Refer to the "Hierarchy of Operating Modes, Functions and Fault
Statuses" for the order of the various operating modes, functions
and fault statuses.
The following functions can be selected using the
‘Settings’
menu:
You can also operate the pump in a calibrated state in all operating
modes if it is to meter extremely precisely. This can be useful when
metering high-viscosity feed chemicals. Calibration is retained over
the entire stroke rate range and over a stroke length range of
0 ... 100%.
This facilitates the switch-over to a fixed adjustable capacity /
stroke rate in the
‘Menu’
via the "External control" terminal.
This permits simple degassing - without the need for an additional
vent valve. The pump works at maximum stroke rate based on the
selected signal to transport gas bubbles out of the liquid end.
The function permits a simple timer program to be set up without
the need for an additional timer module.
The following functions are available as standard:
The function monitors the flow after every single stroke, if a dosing
monitor is connected and if
‘Fast’
is set under
‘Settings
è
Metering
è
Discharge stroke’
or
‘DFMa’
(for the DulcoFlow).
The number of defective strokes, after which the pump is switched
off, can be set in the
‘Settings’
menu.
Information about the liquid level in the dosing tank is reported to
the pump. A two-stage level switch has to be fitted for this purpose,
which is connected to the "Level switch" terminal. It is possible to
connect a suction lance with continuous level measurement to
pumps from 2019 onwards.
The pump can be remotely stopped via the "External control" ter‐
minal.
