Product Overview

M9203-xxx-2(Z) Series Electric Spring Return Actuators Product Bulletin2
Application
M9203-GGx-2(Z) Series Proportional Actuators
M9203-GGx-2(Z) Series Actuators provide proportional
modulation of dampers requiring up to 27 lb·in. (3 N·m)
in HVAC systems that are controlled by an electronic
controller or positioner. The actuator responds to 0 to
10 VDC or 2 to 10 VDC control signals. With the
addition of a 500 ohm resistor, the actuator responds to
a 0 to 20 mA or 4 to 20 mA signal. A 0 to 10 VDC or 2
to 10 VDC feedback signal indicates position and
provides support for master-slave applications.
Manual control system override applications are
supported through field wiring, and include:
• override to MIN position
• override to MAX position
• override to MIN, MID, and MAX position
The M9203-GGA-2 and M9203-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,
when used for environmental air handling purposes, is
an example of the type of space for which these
actuators are configured.
The M9203-GGx-2 actuators have 150 second
constant runtime for 90° rotation. The M9203-GGx-2Z
actuators have 90 second constant runtime for 90°
rotation. When combined with other actuators in a
control system, this choice provides flexibility in
synchronizing the movement of equipment driven from
a single proportional command.
M9203-AGx-2(Z) Series On/Off and Floating
Point Actuators
M9203-AGx-2Z Series Actuators provide on/off control
or modulation of dampers requiring up to 27 lb·in.
(3 N·m) in HVAC systems. Floating point control is
provided from a triac or relay. On/off control can be
provided from a manual switch, controller, auxiliary
switch from a fan motor contactor, or similar device.
Optional Integrated Auxiliary Switch Provides one integrated, line-voltage-capable Single-Pole, Double-Throw (SPDT)
switch with continuously adjustable switch point. Facilitates safety interfacing or
signaling.
Plenum Rated Models Enable use in other environmental air spaces (plenums) in accordance with section
300.22(C) of the National Electric Code.
Override Control
(Proportional Models Only)
Supports manual control system override applications through field wiring.

Features Benefits
IMPORTANT: Use these M9203-xxx-2(Z) Series
Electric Spring Return Actuators 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: Before specifying M9203-xxx-2(Z)
Series Electric Spring Return Actuators for plenum
applications, verify acceptance of exposed plastic
materials in plenum areas with the local building
authority. Building codes for plenum requirements
vary by location. Some local building authorities
accept compliance to UL 1995, Heating and Cooling
Equipment, while others use different acceptance
criteria.
