Description
Outputs relay 1 and 2
Outputs that acts depending on how they have been programmed.
These outputs are potential free and have a maximum load of 5 ampe-
res at 230 Vac.
Fan
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 24 Vdc and it is activated whenever the variator is giving
a voltage output; its maximum load is 9 W.
N.B. It is very important to check the polarity of the variator cables
when they are connected, as if they are connected against the polarity,
the speed variator can burn out.
Digital intakes 1 and 2
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.
Pressure transducer
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.
Communication between
speed variators
This enables communication between various speed variators (up to 8)
through a 2-wire point-to-point cable.
