The following operating options are available via the keys - see the next
figure:
Stop the pump: Press the
[STOP/START]
key.
Start the pump: press the
[STOP/START]
key again.
In
„Batch“
operating mode: briefly press key
[P/OK]
.
In continuous display if you keep the
[P/OK]
key pressed for 2 s, the pump
switches into adjustment mode - see "Adjustment" chapter.
If under
„Service
è
Security
è
Access protect“
the selection
„Lock
menu“
or
„Lock all“
was set, then after pressing the key
[P/OK]
the
„Password“
must first be entered.
Each time you press the
[i/>]
key, you can see a different continuous dis‐
play possibly mixed with error messages. The number of continuous dis‐
plays depends on the identity code, the selected operating mode and the
connected additional devices.
The same applies for auxiliary displays, which are accessed a longer
single press of the key
[i/>]
.
To change a variable (see below) directly in the corresponding continuous
display, press one of the
[arrow keys]
.
If under
„Service
è
Security
è
Access protect“
the selection
„Lock
all“
was set, then after pressing the key
[P/OK]
the
„Password“
must first
be entered.
The directly changeable variables are in detail:
In operating modes
„Manual“
,
„Contact“
and
„Batch“
:
You can change the stroke rate in the "Stroke rate" continuous display.
To change a precisely previously set feed rate (possibly
specified in litres), there is an option of changing it via
the stroke rate. As the stroke rate is digitally processed,
there is no tolerance.
By contrast, changing via the stroke length interferes
with the mechanical tolerance.
You can change the capacity once the pump has been calibrated in the
"Capacity" continuous display.
To change a precisely previously set feed rate (possibly
specified in litres), there is an option of changing it via
the capacity. As the capacity is digitally processed, there
is no tolerance.
By contrast, changing via the stroke length interferes
with the mechanical tolerance.
Only in
„Batch“
mode: The factor is the number of strokes which are trig‐
gered upon an external pulse or pressing of key
[P/OK]
.
