Install Instructions

3. Connect the input control signal:
• Terminal 102 from the master actuator to
Terminal 102 on the slave actuator.
• For AGx models, connect the input control
signal to the common, CW, and CCW terminals
on both the master and the 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 GGx and HGx 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.
• Terminal 103 from the master actuator to
Terminal 103 on the slave actuator.
Note: Set the master actuator jumpers on the GGx
and HGx models according to the action and signal
range desired before proceeding. (Refer to Figure 8
and the Setup and Adjustments, Calibration section.)
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 fail to
drive:
a. Both actuators have the same torque and
control input.
b. One actuator is set as the master and the other
as the slave.
c. The control signal is connected to the master
actuator only.
d. 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 two AGx, GGx, or HGx models in
tandem.
Direction of Action
In the DA mode (factory set), a minimum control signal
drives the actuator to the full CCW position, and a
maximum control signal drives it fully CW. In the
Reverse Acting (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.
