6. Connect the third wire of the 3-conductor shielded
cable between between a lead on fixed resistor (R
2
)
and terminal #3 of the base unit.
7. Connect the available end-lead on the
potentiometer (R
pot
) with the available lead on fixed
resistor (R
2
).
8. Connect the cable shield or drain wire to the
ground screw in the feedback connections terminal
box of the base unit. Do not connect the shield or
drain wire to the two-resistor series.
9. Replace and tighten the base unit cover.
Example: Using a linear potentiometer rated at 400
Ohms/inch on an actuator with 16” of travel.
R
pot(max)
is 400 Ohms/in x 16” = 6.4 kOhm
R
1
= 6.4 kOhm x 4.25 = 27.2 kOhm
R
2
= 6.4 kOhm / 4 = 1.6 kOhm
