Function
Common ground
Pulse output 1, passive open collector output. Pulse
output to flow computer for volume counting.
Function can be set via menu option.
Pulse output 2, passive open collector output. 90° or
180° phase shifted from P1. For pulse fidelity checking
P1 and P2 should be connected to 2 separate inputs of
a flow computer.
Function can be set via menu option.
Status output. Function can be set via menu option
3.5.0.
Current output (I), 0(4) to 20 mA
Passive open collector current sink output. Digital input
