fier). When 'Memory' is activated, the pump adds up the remaining
volume, which could not be processed, up to the maximum capacity of the
memory of 99,999 l. If this maximum capacity is exceeded, the pump goes
into fault mode.
CAUTION!
– The pump maintains the capacity when changing
'Manual' operating mode to 'Batch' oper‐

In operation, the batch size can be changed more easily
by using the "Batch size" continuous display.

The secondary display "Signal current" indicates the incoming current.
You can select 5 types of current signal processing:
'0 - 20 mA'
n
'4 - 20 mA'
n
'Linear curve '
n
'Lower side band'
n
'Upper side band'
n
'0 - 20 mA'
At 0 mA the pump is stationary –
At 20 mA the pump works at maximum speed.
'4 - 20 mA'
At 4 mA the pump is stationary –
At 20 mA the pump works at maximum speed.
With current signals of less than 3.8 mA, an error message appears and
the pump stops (e.g. if a cable has broken).
'Linear curve'
The "Linear curve" symbol appears on the LCD screen. You can enter any
speed behaviour proportional to the current signal. For this purpose, enter
any two points P1 (I1, F1) and P2 (I2, F2) (F1 is the speed at which the
pump is to operate at current I1, F2 is the speed at which the pump is to
operate at current I2...); this defines a straight line and thus the behaviour
is specified:
