Operating instructions
9 Operation
This chapter describes all the operating options available to you if the
pump control is showing a continuous display - then the display does not
contain the symbol for the
[P]
key.
–
For supplementary information, please read the over‐
views "Control elements and key functions" and see the
"Operating/setting diagram" at the end of the operating
instructions.
–
Also take note of the overview "Continuous displays". It
shows which continuous displays are available in which
operating mode and which variables are directly change‐
able in the relevant continuous display.
9.1 Manual operation
The stroke length can be continuously adjusted using the stroke length
adjustment knob in the range 0 ... 100 %. The recommended stroke length
range, in which the set metering quantity can, from a technical point of
view, be accurately reproduced, is 30 ... 100 %
At low stroke rates the pump control switches to stop and go
operation. This occurs with stroke rates, which are less than
1/3 of the maximum stroke rate.
This ensures adequate cooling of the motor at low stroke
rates.
The following operating options are available via the keys - see the figure
on the next page:
Stop the pump: Press the
[START/STOP]
key.
Start the pump: Press the
[START/STOP]
key again.
In operating mode
“Batch”
: Briefly press the
[P]
key.
Press the [P] key for 15 s, if you want to reload the factory
settings prior to calibration!
This deletes the current settings.
In continuous display if you keep the
[P]
key pressed for 2 s, the pump
control switches into adjustment mode - see "Adjustment" chapter.
If
“CODE 1”
was set, then after pressing the
[P]
key, the code must first
be entered.
Each press of the
[i]
key toggles the continuous display output to the
screen to another continuous display. The number of continuous displays
depends on the identity code, the selected operating mode and the con‐
nected additional devices.
