Group 22 Rotary Actuators
Electrical Features
Electric Handswitch:
Time-Saving Local Operation
| Group 22 rotary actuators allow dampers or valves to be
operated at their individual
locations with the built-in electric
Handswitch. This saves time
during installation and
troubleshooting, allowing on-line
adjustments to be made quickly
and easily by bypassing the
electronics in the drive and
control system. The Handswitch
also serves as an electrical backup
in the event of control system failure. |
 |
Auxiliary and Over-travel Limit Switches:
| All Group 22 rotary actuators include two
non-dedicated SPDT switches,
which are cam-actuated directly
by the output shaft. Wiring
connections are provided in the
drive terminal compartment,
allowing for easy access. The
switch trip points are easily
adjusted in the field to operate at
any point in the drive travel
rotation. |
 |
Beck Drive Motor:
Precise, Reliable Control
| The Beck Group 22 rotary actuator motor
design allows for precise control,
with low current draw and no
duty-cycle limitations. The drive's
onboard control electronics
directly feed the motor windings,
thus eliminating external motor
starters or remote mounted
electronics. In addition, the motor
does not coast or overshoot and will not overheat - even under
continuous modulation. |
