The device stores the number of pulses received, which could not yet be
processed, in the stroke memory (if it was enabled).
[STOP/START] is pressed or the "Pause" function is enabled, the
When
stroke memory is deleted.
You can avoid this with the "Memory" function extension:
Additionally, you can activate the "Memory" function extension (Identifier
"m"). When "Memory" is enabled, the pump adds up the remaining
strokes , which could not be processed, up to the maximum capacity of the
stroke memory of 99,999 strokes.
If this maximum capacity is exceeded, the pump goes into fault mode.
Additionally, the "Memory" function extension is enabled by default (Identi‐
fier "m"). When "Memory" is activated, the pump adds up the remaining
strokes , which could not be processed, up to the maximum capacity of the
stroke memory of 99,999 strokes. If this maximum capacity is exceeded,
the pump goes into fault mode.
„ANALOG" menu is available under „Analog" mode in the
The
„Settings" menu. The stroke rate is controlled using an analog current
signal via the "External control" terminal. The secondary display "Signal
current" indicates the incoming current.
You can select three types of current signal processing:
„Standard" ( „0 - 20 mA" or „4 - 20 mA" )
n
„Extended" ( „Curve type" )
n
0 - 20 mA
At 0 mA the pump is stationary –
At 20 mA the pump works at maximum stroke rate.
Between these values, the stroke rate is proportional to the current signal.

4 - 20 mA
At 4 mA the pump is stationary –
At 20 mA the pump works at maximum stroke rate.
Between these values, the stroke rate is proportional to the current signal.
With current signals of less than 3.8 mA, an error message appears and
the pump stops (e.g. if a cable has broken).
The maximum stroke rate can only be reduced under
„Extended" processing types, not under „Standard" pro‐
cessing types.
