Description
Outputs that acts depending on how they have been
programmed. These outputs are potential free and
have a maximum load of 5 amperes at 230 Vac.
When wall-mounted, as there is no cooling from the
motor's own fan, the ventilation system of the wall
mounting shall be used for this cooling.
This output is at 24Vdc and is activated whenever the
pump is running.
Any potential free contact that will perform the
programmed functions can be connected to these
inputs.
N.B. Do not apply voltage to these inputs.
If it is connected, it will be used by the speed variator
to determine the pressure of the installation as well
as the pressure during the "BACK WASH" cycle.
