Operation mode / current (external standard signal)

In the "current" operation mode, the pump functions on the basis of an incoming standard
signal. The incoming signal (0/4-20 mA; 20-0/4 mA or adjustable) is converted into a
metering frequency 0-100 % (stroke/pause ratio), e.g.:
The following operating options can be selected:
• 0 – 20 mA
• 4 – 20mA
• 20 – 0 mA
• 20 – 4 mA
• User defined

0 mA = 0% metering frequency, 20 mA = 100 % metering frequency
4 mA = 0% metering frequency, 20 mA = 100 % metering frequency
20 mA = 0% metering frequency, 0 mA = 100 % metering frequency
20 mA = 0% metering frequency, 4 mA = 100 % metering frequency
n (adjustable) mA = 0 % metering frequency,
n (adjustable) mA = 100 % metering frequency
