rcodeApplications
The M9220-Bxx-3 On/Off Actuators are direct-mount,
spring return electric actuators that operate on AC 24 V
power at 50/60 Hz, DC 24 V power, AC 120 V power at
60 Hz, or AC 230 V power at 50/60 Hz. 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-Bxx-3 On/Off Electric Spring Return
Actuator provides a running and spring return torque of
177 lb
in (20 N
m). Two like models mounted in tandem
using the M9000-158 Tandem Mounting Kit deliver
twice the torque or 354 lb
in (40 N
m). Integral line
voltage auxiliary switches are available on the BxC
models to indicate end-stop position, or to perform
switching functions within the selected rotation range.
IMPORTANT:
Use this M9220-Bxx-3 On/Off
Electric Spring Return Actuator only to control
equipment under normal operating conditions.
Where failure or malfunction of the M9220-Bxx-3
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
M9220-Bxx-3 actuator.
IMPORTANT :
Utiliser ce M9220-Bxx-3 On/Off
Electric Spring Return Actuator uniquement pour
commander des équipements dans des conditions
normales de fonctionnement. Lorsqu'une défaillance
ou un dysfonctionnement du M9220-Bxx-3 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
M9220-Bxx-3 actuator.
