Honeywell S05 Series - Operation

S05, S10, S20 SERIES SPRING RETURN DIRECT COUPLED ACTUATORS
13 63-2607—08
OPERATION
The actuator is designed to be used in ventilating and air
conditioning installations to operate valves, dampers,
ventilation flaps and louvers requiring torque up to the rating.
(For ratings, see the Specifications section.) If the power fails,
the actuator will spring return to the start position.
The actuator is operated by a proportional controller. When
using a proportional controller, the actuator drives toward its
fully open position when the input signal increases; the
actuator drives toward the fully closed position when the input
signal decreases. The actuator stops when the input signal
reaches the desired proportional control point.
IMPORTANT
The actuator is designed to respond to DDC
Controller instantaneous contact closures. Take care
not to short cycle the actuator. Unstable damper
control can cause premature actuator failure.
Actuator Override
To override the control signal (for freeze protection or similar
applications):
1. Override to full open:
a. Disconnect the input signal (from terminal 3).
b. Apply 24 Vac to terminal 3.
c. See Fig. 27.
2. Override to full closed:
a. Disconnect the input signal (from terminal 3).
b. See Fig. 28.
Fig. 27. Override to full open.
Fig. 28. Override to full close.
End Switches
Some models include end switches (see Table 2). For wiring
details, see Fig. 11.
SPDT Switches (Fig. 29)
For SPDT end switch wiring, see Fig. 11.
