Applications
The M9204-GGx-2(Z) Series Proportional Electric Spring Return Actuators are direct-mount actuators that operate
on AC/DC 24 V power. These bidirectional actuators do not require a damper linkage, and are easily installed on
round shafts from 1/4 to 1/2 in. (6 to 12 mm) or square shafts from 1/4 to 5/16 in. (6 to 8 mm) using the standard
shaft clamp included with the actuator.
A single M9204-GGx-2(Z) Series Proportional Electric Spring Return Actuator provides 35 lb·in. (4 N·m) running
and spring return torque. An integral line voltage auxiliary switch, available only on the M9204-xxB-2(Z) models,
indicates end-stop position, or performs switching functions within the selected rotation range.
M9204-GGA-2 and M9204-GGA-2Z actuators include plenum-rated cables and are specially configured for
installation in spaces used for environmental air-handling purposes other than ducts and plenums as specified in
National Fire Protection Association (NFPA) 70: National Electrical Code section 300.22(C), Other Space Used for
Environmental Air. The space over a hung ceiling used for environmental air handling purposes is an example of
the type of space for which these actuators are configured.
IMPORTANT: Use this M9204-GGx-2(Z) Series Proportional Electric Spring Return Actuator only to control
equipment under normal operating conditions. Where failure or malfunction of the 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 actuator.
IMPORTANT : Utiliser ce M9204-GGx-2(Z) Series Proportional Electric Spring Return Actuator uniquement
pour commander des équipements dans des conditions normales de fonctionnement. Lorsqu'une défaillance ou
un dysfonctionnement du 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 actuator.
Installation
The M9204-GGx-2(Z) Series Proportional Electric Spring Return Actuators mount directly to the surface in any
convenient orientation using two No. M3.5 x 9.5 mm self-drilling sheet metal screws and the anti-rotation bracket
(parts included with the actuator). No additional linkages or couplers are required. Electrical connections are
color-coded and identified with numbers permanently marked on the actuator cable. A tag on the actuator cable
identifies the electrical connections and wiring details are included on the actuator housing.
IMPORTANT: Do not install or use this M9204-GGx-2(Z) Series Proportional Electric Spring Return Actuators
in or near environments where corrosive substances or vapors could be present. Exposure of the electric
actuator to corrosive environments may damage the internal components of the device, and will void the
warranty.
