9.6.2 Flow Monitor
In order for the pressure sensor (if installed) to
function as a dosing controller, the dosing controller
must be switched on, see section
9.10 Flow Monitor .
9.6.3 Memory function
The memory function is used to store excess contact
signals for processing later, see section
9.2.7 Memory function .
• Switch the memory function on/off with "Up" /
"Down".
• Press the "Menu/Info" button (confirm the setting
and move on to the next menu item), or
• press the "Start/Stop" button (confirm the setting
and close the second function level).
9.6.4 Weighting of current input/output
In current input/output operation, the dosing capacity
is controlled via the current signal. The pump emits a
current signal as a feedback for control rooms or
master/slave applications.
9.6.5 Batch menu / batch mode
In batch mode, a defined batch quantity is dosed
with a defined dosing flow.
See section
9.11 Batch menu / batch mode .
9.6.6 Timer menu / timer mode
In timer mode, a defined batch quantity is dosed with
a defined dosing flow and a defined start time.
See section
9.12 Timer menu / timer mode .
9.6.7 PROFIBUS menu
The "PROFIBUS" menu item is only displayed for
pumps with PROFIBUS interfaces. The PROFIBUS
interface is activated/deactivated in this menu and
the bus address is specified.
9.6.8 Slow mode
Activating the slow-mode function lengthens (slows
down) the suction stroke. For example, cavitation is
thus reduced with viscous media.
Slow mode can be activated in any operating mode.
9.6.9 Display/resetting of total dosing capacity
The total capacity dosed since the value was last
reset is displayed.
To reset the value,
1. press the "Up" button.
– "dEL" appears in the display.
2. Press the "Start/Stop" button.
– The total dosing capacity is deleted.
• Press the "Menu/Info" button (confirm the setting
and move on to the next menu item), or
• press the "Start/Stop" button (confirm the setting
and close the second function level).
9.6.10 Display of total number of operating hours
The operating hours counter indicates the operating
time of the drive, e.g. to check maintenance
intervals. The maximum number of operating hours
that can be displayed is 99,990 h (display = 9999).
The operating hours counter cannot be reset.
9.7 Service level
Open the service level
•
to modify the switch assignments of the control
unit,
• to set the pump type, or
• to select the unit of measurement for the dosing
flow (l/h or gal/h) that will be displayed.
9.7.1 Modifying the switch assignment
The service level can only be accessed when the
power supply is switched on.
1. Simultaneously press the "Menu/Info" and
"Down" buttons and hold them down.
2. Switch on the power supply.
– The LED alternately flashes red and green.
3. Release the "Menu/Info" and "Down" buttons.
4. Press the "Start/Stop" button.
5. Press the "Up" button.
– The LED lights up yellow.
– "Func" appears in the display.
6. Press the "Menu/Info" button.
– The service level is opened.
Note
For weighting of current input/output,
see also 9.9 Current signal control
0-20 mA / 4-20 mA.
Note
The maximum flow rate of the pump
decreases. The time for the suction
stroke increases. The maximum stroke
rate in slow mode is 120 1/min.
Note
The maximum value that can be
displayed is 9999 l. If this value is
exceeded, the counting starts again
at zero.
Note
Multiply the number displayed by 10 to
determine the number of operating
hours.
Note
You are modifying the default settings
of your control unit. They will therefore
differ from the technical data.
