with the help of a screwdriver. The mang plug f
or the 3‑way controller connector is
supplied with the pump.
The connector supplies the power to the vent valve or fan connected to the 3‑pins. The
connector mang plug is shown in Figure: Controller connector showing pin numbers on
page 30, with the polarity of the pins marked, when the vent valve or fan is set to on.
The 24 V d.c. output on the controller connector is protected from the overload or short
circuit to 0 V d.c. / 24 V d.c. Rtn / chassis. The output supplies the current given in Table:
Controller technical data on page 30. For higher currents, the output voltage will
decrease and can set to o to limit the current.
