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

Applications
The M9220-GGx-3 Proportional Electric Actuators are
direct-mount, spring return electric actuators that
operate on AC/DC 24V power. These bidirectional
actuators do not require a damper linkage, and are
easily installed on dampers with 1/2 to 3/4 in. or 12 to
19 mm round shafts, or 3/8 and 1/2 in. or
10, 12, and 14 mm square shafts using the standard
shaft clamp included with the actuator. An optional
M9220-600 Jackshaft Coupler Kit is available for
3/4 to 1-1/16 in. or 19 to 27 mm round shafts, or
5/8 and 3/4 in. or 16, 18, and 19 mm square shafts.
A single M9220-GGx-3 Series Proportional Electric
Spring Return Actuator provides a running and spring
return torque of 177 lb·in (20 N·m). Two or three like
models mounted in tandem deliver twice or triple the
torque (354 lb·in [40 N·m] or 531 lb·in [60 N·m]).
Integral line voltage auxiliary switches are available on
the GGC models to indicate end-stop position or to
perform switching functions within the selected rotation
range.
IMPORTANT: Use this M9220-GGx-3 Proportional
Electric Spring Return Actuator only to control
equipment under normal operating conditions.
Where failure or malfunction of the electric actuator
could lead to personal injury or property damage to
the controlled equipment or other property,
additional precautions must be designed into the
control system. Incorporate and maintain other
devices, such as supervisory or alarm systems or
safety or limit controls, intended to warn of or protect
against failure or malfunction of the electric actuator.
IMPORTANT: Utiliser ce M9220-GGx-3 Proportional
Electric Spring Return Actuator uniquement pour
commander des équipements dans des conditions
normales de fonctionnement. Lorsqu'une défaillance
ou un dysfonctionnement du electric actuator risque
de provoquer des blessures ou d'endommager
l'équipement contrôlé ou un autre équipement, la
conception du système de contrôle doit intégrer des
dispositifs de protection supplémentaires. Veiller
dans ce cas à intégrer de façon permanente
d'autres dispositifs, tels que des systèmes de
supervision ou d'alarme, ou des dispositifs de
sécurité ou de limitation, ayant une fonction
d'avertissement ou de protection en cas de
défaillance ou de dysfonctionnement du electric
actuator.
