3 NM SERIES SPRING RETURN DIRECT COUPLED ACTUATORS
9 31-00141M—03
2. Return to full closed:
a. Disconnect the input signal (from terminal 3).
b. See Fig. 20.
Fig. 19. Override to open position.
Fig. 20. Return to closed position.
CHECKOUT
Modulating/Floating Operation
1. Mount actuator for required application (either
clockwise
or counterclockwise rotation to
open the damper).
2. Connect power to power and common wire. (See Fig.
11 and Table 3.)
3. Set “Mode Select” dial to desired control signal.
(See Fig. 5.)
4. Apply control signal for actuator full open or full
closed position. (See Fig. 11 and Table 3.)
a. (0)2-10 VDC: apply 10 VDC signal to control wire
(WHITE).
b. 10-(0)2 VDC: apply (0)2 VDC signal to control
wire (WHITE).
c. (0)4-20 mA: apply 20 mA signal to control wire
(WHITE).
d. 20-(0)4mA: apply (0)4 mA signal to control wire
(WHITE).
e. Floating: apply 24 VAC to appropriate 0°-90°
(WHITE) or 90°-0° (BROWN) wire.
5. Actuator drives to full open or full closed position.
6. Apply control signal for actuator 0% position.
(See Fig. 11 and Table 3.)
a. (0)2-10 VDC: apply (0)2 VDC signal to control
wire (WHITE).
b. 10-(0)2 VDC: apply 10 VDC signal to control wire
(WHITE).
c. (0)4-20 mA: apply (0)4 mA signal to control wire
(WHITE).
d. 20-(0)4mA: apply 20 mA signal to control wire
(WHITE).
e. Floating: apply 24 VAC to appropriate 0°-90°
(WHITE) or 90°-0° (BROWN) wire.
7. Actuator drives to full open or full closed position.
Spring Return Operation
1. Mount actuator for required application (either
clockwise
or counterclockwise rotation to
open the damper or valve).
2. Connect power to power and common wire. (See Fig.
11 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. 14.
b. mA Input Signal: apply 10-12 mA signal to control
wire (WHITE). See Fig. 14.
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.
