3 NM SERIES SPRING RETURN DIRECT COUPLED ACTUATORS
timing. When the signal is disconnected, the actuator will
drive to the fully closed position with normal operation
timing.
CAUTION
Do not use fast test mode for permanent
operation.
Lifetime will be reduced if this mode is used
permanently. This mode is intended to be used only
for initial commissioning/testing of the system
after installation. Power consumption is not
specified in this mode.
Auxiliary Switches
Some models include Auxiliary switches. For wiring details
see Fig. 10.
Actuator Override
To override the control signal (for freeze protection or
similar applications):
1. Override to full open (fast commissioning, drive
mode lower than 30 sec):
a. Disconnect the input signal (from terminal 3).
b. Apply 24 VAC to terminal 3.
c. See Fig. 16.
2. Return to full closed:
a. Disconnect the input signal (from terminal 3).
b. See Fig. 17.

CHECKOUT
Modulating/Floating Operation
1. Mount actuator for required application (either
clockwise or counterclockwise
open the damper).
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 full open or full
closed position. (See Fig. 10 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. 10 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.
