3. Connect the input control signal:

• Terminal 102 from the master actuator to

Terminal 102 on the slave actuator

• For D24-210 and -280 models, connect the input

control signal to the common, CW, and CCW

terminals on both the master and slave actuators.

(See Figure 7).

• Terminal 103 from the master actuator to

Terminal 103 on the slave actuator

b. When mounting two actuators back-to-back on

the same shaft, connect:

• For DM24-140, -210, and -280 Models, connect

the control signal to the master actuator and

connect 24 VAC/VDC power to both the master

and slave actuators.

• Terminal 101 from the master actuator to

Terminal 102 on the slave actuator

• Terminal 102 from the master actuator to

Terminal 101 on the slave actuator

IMPORTANT: For proper tandem operation,

do not connect the control input to the slave unit.

Note:

• Terminal 103 from the master actuator to

Terminal 103 on the slave actuator

Set the master actuator jumpers on the

DM24-140, -210, and -280 models according to the

action and signal range desired before proceeding.

(Refer to Figure 8 and the Setup and Adjustments,

Calibration section.)

Note: The total wire length for these connections

may be up to 30 ft (9 m).

4. Make sure of the following if the actuators

configured for tandem operation stall or do not

drive:

• Both actuators have the same torque and

control input.

• One actuator is set as the master and the

other as the slave.

• The control signal is connected to the master

actuator only.

• Terminal 101, Terminal 102, and Terminal 103

are connected properly, as described in

Step 2.

Setup and Adjustments

Calibration

Calibrate only the actuator designated as the master

when using a combination of two D24-210 or -280 or

two DM24-140, -210, or -280 models in tandem.

Direction of Action

In the DA mode, a minimum control signal drives the

actuator to the full CCW position, and a maximum

control signal drives it fully CW. In the RA mode, a

minimum control signal drives the actuator to the full

CW position, and a maximum control signal drives it

fully CCW. To set an actuator for RA, proceed to the

section for the appropriate model.

IMPORTANT: Adjust the rotation range before

changing the direction of action.
