ELECTRICAL FEATURES – Group 22 Rotary Actuators

Electric Handswitch:
Time-Saving Local Operation

g22_electrical_1

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

g22_electrical_3a

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.
