Speed: analogue output (J1) (Universal+ only)
A current analogue signal within the range 4-20mA is
available between the O/P (output) terminal and the
GND terminal. The current is fixed and directly
proportional to the pump speed. 20mA = maximum
speed, 4mA = zero speed.
There is also an option to match the scale of the 4-
20mA input if this has been reconfigured by the user.
This option is available in the Control settings menu.
Note: If the mA output is to be used for reading from a
multimeter (set on mA), a 250Ω resistor is required in
series.
Earth shielding terminals
4.8mm spade terminals are supplied for earth shielding of
cables. The input cable and output cable earths can be
connected to either terminal.
Keep 4-20mA and low voltage signals separate from mains power. Use
separate glanded input cables.
