Caution: For floating input signals the
cables between the controller and the
Forta should not exceed 328' (100m)
with the cables connected
(16 AWG)
to
one actuator.
When installed with 3 conductors with
very long lengths (floating control),
where control signal reference is
connected to G, the motor current of
the actuator will cause varying voltage
loss in the cable and thus in the
reference level. Forta which has a
highly sensitive control signal input,
will detect the varying signal and
follow it, which makes it difficult for the
actuator to find a stable position.

Cable Lengths: The wires to G, H
should be max of 328 ft (100m). min
AWG 16, all other proportional input
signal input wires should be a max of
656 ft (200m) min AWG 20.
Please refer to the Wiring Examples
for wiring instructions.
