M100A Series On-Off/Floating Control Actuator

IMPORTANT: All M100A Series actuators are
intended to control equipment
under normal operating conditions.
Where failure or malfunction of
M100A actuators could lead to an
abnormal operating condition that
could cause personal injury or
damage to the equipment or other
property, other devices (limit or
safety controls) or systems (alarm
or supervisory) intended to warn of,
or protect against, failure or
malfunction of M100A actuators
must be incorporated into and
maintained as part of the control

Tools Needed
• 1/4 in. (6 mm) flat-blade screwdriver
• punch and hammer


Observe the following ranges and limitations:
• Do not install the actuator in atmospheres with
explosive vapors, escaping gases, or in
environments where substances corrosive to the
device’s internal components could be present.
• Seal wiring entering into return air systems to
prevent aspiration of corrosive air into the actuator.

Direction of Rotation

The direction of rotation on all M100A models is field
adjustable from 45 to 270°. The actuators are factory
set at the zero position and for 90° travel. The zero
position is approximately 10° Clockwise (CW) from
vertical. Spring return models return
Counterclockwise (CCW) to the zero position when
power is removed.


Follow installation steps for the linkage kit used to
couple the actuator and the controlled device. When
not utilizing a damper linkage kit, use four 1/4 x 1 in.
bolts to mount the actuator (not included).
Upright mounting of the actuator is preferred with the
output shaft parallel to the floor. Locate the actuator
where the shaft and wiring terminals are accessible.
IMPORTANT: For installations using the
CVR83A-600R Weather Cover Kit,
mount the actuator in an upright
position so water will not enter the
enclosure and damage the actuator.
Make all linkage connections to the drive shaft on the
load end of the actuator, rated for up to 200 lb
dead weight. Limit the load on the auxiliary end to 10 lb
dead weight.
When mounting on a valve, mount the actuator above
the horizontal plane of the valve piping. This avoids
damage to the actuator if the valve leaks or develops
Note: Valve medium temperatures above 250°F
(121°C) are acceptable only if the actuator’s
maximum ambient temperature is below 105°F
