Tandem Operation: GGx Master with
GGx Slaves
GGx Slaves
The tandem configuration (Figure 13 and Figure 15)
provides twice (with two actuators) or triple (with three
actuators) the running and spring return torque of a
single actuator, or 354 lb·in (40 N·m), 531 lb·in
(60 N·m). The actuators may be mounted in tandem
using the M9000-158 Tandem Mounting Kit. To mount
a third actuator, user-configured bracketing is
required..

Follow these guidelines for tandem operation:
•
Two or three M9220-GGx-3 actuators may be
operated in tandem on the same shaft. If mounting
two actuators, see Figure 13; for three actuators,
see Figure 15.
operated in tandem on the same shaft. If mounting
two actuators, see Figure 13; for three actuators,
see Figure 15.
•
Each actuator requires separate 24 volt power.
When two or more actuators connected in tandem
share a common power source, the total maximum
power draw is actually 1.5 times the normal
running current for each actuator.
(Total Power = Number of Actuators x Running
Power x 1.5).

Only one of the actuators can be configured as the

The other GGx actuator(s) must be configured as
slave(s), by setting the tandem selector switch to

The master can accept DC 0-10 V or DC 2-10 V, or
4-20 mA command signals based on the master’s
switch settings and/or external resistor.
