CN05,CN10 SERIES DAMPER ACTUATORS FOR FLOATING/2-POSITON CONTROL

Floating/2-Position Run Mode

If the function selection switch has been set to one of the two
floating/2-position control settings—and if the actuator is wired
correspondingly (see Fig. 7, Fig. 8, and Fig. 9)—then as soon as
operating power is applied, the shaft adapter will run according to
the control signals applied.
Table 1 describes the behavior ("stops," rotates "CCW," or
rotates "CW") of the CN6105/CN6110 in dependence upon the
control signals (switch "open" or "24 Vac/dc") applied to terminals
3 and 4, the function selection switch setting, and the manner in
which the actuator is wired (either for floating mode: see Fig. 7;
or for 2-position mode: see Fig. 8).

Table 2 describes the behavior ("stops," rotates "CCW," or

control signals (switch "open" or "230 Vac") applied to terminals 1
and 3 and the function selection switch setting: only one manner
of wiring is permitted (see Fig. 9).

MANUAL ADJUSTMENT

IMPORTANT
To prevent equipment damage, before manual
adjustment, you must remove power or set the func-
tion selection switch to the "Service/Off" position.
After removing power or setting the function selection switch to
the "Service/Off" position, the gear train can be disengaged using
the declutch button, permitting the shaft adapter to be manually
rotated to any position.

Limitation of Rotation Stroke

Two adjustable mechanical end limits are provided to limit the
angle of rotation as desired (see Fig. 3). The mechanical end
limits must be securely fastened in place.
Fig.3.
To ensure tight closing of the dampers, the shaft adapter has a
total rotation stroke of 95°.

INTERNAL END SWITCHES

The internal end switches "A" and "B" are changeover switches
which are activated when the shaft adapter moves past a position
of 5° and 85°, respectively (see also Table 5).
