The SELCO E7800 Motorised
Potentiometer is normally used as a link between increase/decrease relay
contacts (or push buttons) and equipment requiring control from an external
potentiometer (e.g. the speed trim of an electronic governor).
All three wires of the
potentiometer are easy to connect to, on external terminal block, therefore
providing the best possible flexibility for almost any application.
The design of the E7800
is made so, the potentiometer will “remember” its position even when supply is
lost.
The potentiometer can
easily be replaced when installed. There are access from the back of the
device, when the four corner screws are removed. With an alan key the coupling
can be taken of the potentiometer shaft, and a new potentiometer can be
installed in the reverse order.
The supply to the unit is
so it only has active power when movement is needed. The neutral or minus is
connected at all times, but only when movement is needed is the line or
positive connected to either a terminal for increase or for decrease.
