Operating instructions

Under menu option
“ER” (Error) you can activate error processing for the
“Curve” processing type. For current signals below 3.8 mA, a fault mes‐
sage appears and the pump stops.
8.5.3 "Contact" operating mode settings (CNTCT menu)
Alongside those described in more detail in the chapter "Programmable
function settings (SET menu)" the “CNTCT” menu is also available in
“Contact” operating mode via the “SET” menu.
“Contact” operating mode allows you to trigger individual strokes or a
stroke series. You can trigger the strokes via a pulse sent via the "external
control" terminal. The purpose of this operating mode is to convert the
incoming pulses with a reduction (bridge) or small step-up into strokes.
CAUTION!
If you change into another operating mode, the factor is reset
to "1".
With the identity code version "Contact - identity code: External with pulse
control" you can enter after how many pulses a stroke should occur. "Con‐
tact - identity code: External with pulse control" is intended for small
metering quantities.

The number of strokes per pulse depends on the factor which you input.
By use of the factor you can multiply incoming pulses by a factor between
1.01 and 99.99 or reduce them by a factor of 0.01 to 0.99:
Number of strokes executed = factor x number of incoming pulses
