3. If necessary, install conduit between the feedback
unit and the base unit following applicable local and
national electrical codes. Route the 3-conductor
shielded cable between the two units.
4. Connect one wire of the 3-conductor shielded cable
between terminal 1 on the feedback unit and terminal
1 on the base unit.
5. Connect the second wire of the 3-conductor
shielded cable between terminal 2 on the feedback
unit and terminal 2 on the base unit.
6. Connect the third wire of the 3-conductor shielded
cable between terminal 3 on the feedback unit and
terminal 3 on the base unit.
7. 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 any terminal on the feedback unit.
8. Replace and hand tighten all covers.
Using an External 10 kOhm Potentiometer
as a Remote Travel Sensor
Note
Potentiometer travel must be between
1.3 and 1.6 times greater than the
actuator travel. For example: if an
actuator has a travel of 9 inches, then
a linear potentiometer must be
selected with a rated travel between
11.7 and 14.4 inches. The resistive
element must be tapered from 0 kOhm
to 10 kOhm over rated travel of the
potentiometer. The actuator will only
use 63 to 76% of the potentiometer’s
rated travel.
