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
Slow mode reduces the maximum dosing flow of the pump in two
stages to 66 % (slow mode 1) or 41 % (slow mode 2).
By increasing the minimum suction time, cavitation is, for
example, reduced with viscous media.
Slow mode can be activated in any operating mode. In the
slow-mode menu, the slow mode function is set and the
slow-mode factor is selected.
Setting slow mode
In the second function level, "SL:OF" appears in the display.
• Use the "Up" and "Down" buttons to switch between normal
operation (SL:OF), slow mode 1 (SL:01) and slow mode 2
(SL:02).
– The current slow-mode factor appears in the display.
• 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 electronics,
• 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.

Note
The maximum flow rate of the pump decreases. The
maximum stroke rate is 120 l/min. in slow mode 1
and 74 l/min. in slow mode 2. The minimum
adjustable flow rate is maintained.
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.
