Spring Return Operation
1. Mount actuator for required application (either
clockwise or counterclockwise
open the damper or valve).
2. Connect power to power and common wire. (See Fig.
10 and Table 3.)
3. Set "Mode Select" dial to desired control signal.
(See Fig. 5.)
4. Apply control signal for actuator 50% position.
a. VDC Input Signal: apply 5-6 VDC signal to con-
trol wire (WHITE). See Fig. 13.
b. mA Input Signal: apply 10-12 mA signal to control
wire (WHITE). See Fig. 13.
c. Floating: apply 24 VAC to appropriate 0°-90° (3)
or 90°-0° (4) wire until device reaches 50%.
5. Allow the actuator to drive to 50% position.
6. Disconnect power wire (RED).
7. Actuator spring returns to 0% position.
8. Re-connect power wire (RED), actuator drives back
toward 50% position.
Feedback Operation
1. Connect a multi-meter, set for VDC, to common
(BLACK) and feedback (BROWN) wire.
2. Apply the same signal as in step 4 of Modulating
Operation.
3. The multi-meter reading increases to match the
input signal as actuator drives towards full open or
full closed position.
4. Apply the same signal as in step 6 of Modulating
Operation.
5. The multi-meter reading decreases to match the
input signal as actuator drives towards 0% position.
Direct Checkout
1. Mount actuator for required application (either
clockwise or counterclockwise
open the damper or valve).
2. Check damper position and make sure that 24
VDC/VAC is present at the appropriate connections.
(See Fig. 10.)
3. Apply control signal to the appropriate connections
to move the damper to the opposite position. The
actuator should drive the damper or valve.
4. If actuator does not run, verify that the actuator is
properly installed for either clockwise
terclockwise rotation.
5. If actuator is correctly installed and still does not
run, replace the actuator.

NFC description
• Device complies with ISO/IEC 14443A.
rotation to • NFC can be utilized for communication between the
actuator and NFC equipped device.
• The NFC access area location is shown in Fig. 18.
• If the NFC access point is facing the damper, limited
access from the edge on the side of the power wires
may be possible depending on installation and NFC
device capabilities.

Security instructions
Physical security control, such as a locked cabinet,
equipment room or any other placement of the device that
restricts physical access to it, is recommended to prevent
device tampering and unauthorized manipulation of the
parameters accessible via NFC connection. Connection to
the device via NFC is secured using a PIN. Each device is
preset with a factory default PIN. The factory default PIN is
or coun-
2586 and is the same for all devices of this product family.
It is recommended that the default PIN is changed to a
user unique PIN. The user unique PIN can be canceled
using the factory default PIN at any time.
