M9220-GGx-3 Proportional Electric Spring Return Actuators Installation Instructions

Tandem Operation: GGx Master with
GGx Slaves
The tandem configuration (Figure 14 and Figure 16)
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 14; for three actuators,
see Figure 16.
•
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
master. Set the selector switch to the master
position (Figure 15).
•
The other GGx actuator(s)
must
be configured as
slave(s), by setting the tandem selector switch to
the slave position.
•
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.
•
The master and slave(s) must have matching
RA/DA settings.
