M9216 Series Electric Spring Return Actuators Installation Instructions 7
1. Move Mode Switch 5 on the other GGx actuator to
the slave position.
2. Connect the control signal to the master actuator
only, and set the remaining mode switches on the
master unit according to the action and signal
range desired. (Refer to the
Calibration section.)
3. Connect Terminals 101, 102, and 103 from the
master actuator to the corresponding terminals on
the slave actuator. (See Figure 12.)
Note: The total wire length for these connections
may be up to 30 ft (9 m).
4. Connect 24 VDC or VAC power to each actuator.
HGx Models
HGx models are factory set with Jumper W4 in the
master position. Designate one unit as the
master actuator. Refer to Figure 13, and proceed as
follows:

1. Move Jumper W4 on the other HGx actuator to the
slave position.
2. Connect the control signal to the master actuator
only, and set the remaining jumpers on the master
unit according to the action and signal range
desired. (Refer to the
Calibration section.)
3. Repeat Steps 3 through 4 from the GGx Models
section.
If the actuators configured for tandem operation stall or
do not drive:
•
Make sure both actuators are from the same
model group.
•
Make sure one actuator is set as the master and
the other actuator as the slave.
•
Make sure the control signal is connected to the
master actuator only.
•
Make sure Terminals 101, 102, and 103 are
connected properly.
•
Make sure the couplers are properly installed.
(Refer to the
Installation, Spring Return Direction
section.)
Setup and Adjustments
Calibration
Only the actuator designated as the master needs to
be calibrated when two BGx, GGx, or HGx models are
used in tandem.
Direction of Action
Drive direction is dependent on the position of
Jumper W1 or Mode Switch 2 and the spring return
direction as shown in Table 2. To change the spring
return direction, see the
Installation, Spring Return
Direction section.

To set an actuator for Reverse Acting (RA), proceed to
the section for the applicable model.
AGx Models
Reverse the control wiring connections at Terminals 3
and 4 to select RA operation for the floating models.
(See Terminal Block 1 in Figure 8.)
