16 Application
Program Sequence
The pump is in the basic operating state (Manual program). To start the pumping pro-
cess, press the selecting knob or the foot switch. To stop the pump, press the selecting
knob or the foot switch again. In this case, you can change the pump
rate (Speed) before and during a pumping procedure in a range between 10 – 100
(infinitely; does not correspond to revolutions per minute).
After re-pressing the left Speed soft key, the Duration soft key is available.
A specific pump time can be entered via Duration.
Note: When you enter a specific pump time in Duration, the current pump
time is set to zero.
The Esc key has two different functions, depending on the state of the program:
a) The left soft key (Speed|Duration) has a white background (active). Pressing the
Esc key deactivates the current soft key function (Speed|Duration) so that the
respective value (Speed|Duration) can no longer be set (no white background).
b) The left soft key (Speed|Duration) does not have a white background (inactive).
By pressing the Esc key, the current pump time is reset.
To switch off the pump, use the On|Off switch on the back panel of the pump
housing.
6.1.2 Manual Record Program (Manual Operating Mode with Data Collection)
For preparing the pump for initial start-up, see Chapter 6.
This mode is reached by pressing the Menu key once. The Program Menu appears
on the display and lists the following options (Fig. 7):
a) Manual
b) Manual Record
The different operating modes are selected by turning the selecting knob.
For final selection of an operating mode, press the selecting knob (in this case:
Manual Record).
The difference between the Manual program and this Manual Record program is that
when the latter begins, a data record can be collected in the manual mode.
The display will now prompt a barcode scan (Scan Operator, Fig. 8).
The control unit now waits until either data recording is started by pressing the left
Scan soft key (barcode is scanned via the internal barcode scanner), the current data
set recording (current scan process) is bypassed by pressing the Esc key or the pro-
gram is stopped and returned to the Program menu by pressing the Menu key.
Note: The Scan soft key does not have to be pressed for an external scanner.
The control unit automatically reads the data from the external scanner and
assigns it to the appropriate data records. In the example in Fig. 8, this data is
assigned to the "Operator" parameter. The control unit automatically switches
to the next parameter as soon as the data have been scanned.
