This function level can only be opened when the pump is
stopped.
1. When the pump is stopped (LED lights up red), press the
"Menu/Info" button.
– The first function level is opened.
2. Navigate in the first function level by repeatedly pressing the
"Menu/Info" button.
3. Use the "Up" and "Down" buttons to modify the settings in the
relevant menu as shown in fig. 24.
4. Press the "Start/Stop" button to confirm the settings and to
exit the first function level.

9.4.2 Manual control
Dosing with manual on/off and manually adjustable dosing
flow
In this operating mode, all the settings are entered on the pump
by the operator.
• Use the "Start/Stop" button to start or stop the pump.
• Use the "Up" and "Down" buttons to increase or decrease the
flow rate. This can be done when the pump is stopped or when
it is running.
Fig. 25 Display: manual control
The maximum displayed/adjustable flow rate is automatically set
according to the selected pump type and the calibrated stroke
volume.
Input range for the flow rate
9.4.3 Contact signal control
• Use the "Start/Stop" button to start or stop the pump.
For continuous dosing in a process
For each signal received at the contact input of the pump
(e.g. from a water meter with reed contact output), the pump
doses the set dosing capacity. The dosing is continuously
distributed between the incoming contacts via a controller.
The maximum dosing capacity must not be exceeded.
Input range for the dosing capacity per contact
Even if the pump receives more contact signals than it can
process at the maximum flow rate, it only runs in continuous
operation with a maximum stroke frequency of
180/min. 120/min. in slow mode).
Fig. 26 Display: contact signal control
Use the "Up" and "Down" buttons in the first function level to set
the dosing volume for each contact signal.
1. When the pump is stopped (LED lights up red), press the
"Menu/Info" button.
– The first function level is opened.
2. Use the "Up" and "Down" buttons in the "contact signal
control" menu to set the dosing volume per contact signal.
3. Press the "Start/Stop" button to confirm the settings and to
exit the first function level.
– The pump is running (LED lights up green).
9.4.4 Current signal control 0-20 mA / 4-20 mA
For current signal control, see section 9.9 Current signal control

.
9.5 Second function level
9.5.1 Opening / exiting the second function level
Open the second function level
• to set the access code,
• to enable or disable functions such as Flow Monitor or
memory,
• to enter settings for operating modes such as batch mode,
• to display the total number of operating hours and total dosing
capacity,
• to carry out a calibration, or
• to modify the assignment between the current input/output and
dosing rate.
This function level can only be opened when the pump is stopped
(LED lights up red).
