• 4 - 20 mA: at 4 mA the S2Ca does not operate
at 20 mA the S2Ca operates at 180 strokes/min.
Between these two extremes the stroke rate is proportional to the electrical
signal.
For signals of below 3.8 mA a fault will be detected and the S2Ca will stop
(e.g. cable break).
• Curve: In the “curve” processing mode you can programme the S2Ca ratios.
There are 3 options available:
• = straight line
• = lower band
• = upper band

Straight line:
The following symbol appears in the LCD display: .
You can enter any stroke frequency ratio for the S2Ca in proportion to the electrical signal.
You must enter two points P1 (I1, F1) and P2 (I2, F2). F1 is the stroke rate at which the pump
should operate at current I1: the straight line and the ratio are fixed accordingly:

NOTE
Draw a diagram like the one above - with values for (I1, F1) and (I2, F2) - in order to set
the S2Ca to your required stroke rate!
