6. Connect the third wire of the 3-conductor shielded

cable between between a lead on fixed resistor (R

)

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

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

= 6.4 kOhm x 4.25 = 27.2 kOhm

 R

= 6.4 kOhm / 4 = 1.6 kOhm
