Group 22 Beck rotary actuators offer the benefit of a total control package, utilizing reliable electronics to match the speed and precision of your process instrumentation. Standard Group 22 modulating drives are equipped with Beck’s Digital Control Module, which controls the position of the drive according to the input signal it receives. A position feedback signal is delivered to the DCM from the position sensing device (Beck’s Contactless Position Sensor). This signal is continuously compared to the demand input signal. A change in the input signal results in an immediate repositioning of the drive to balance the two signals.

FACTORY CALIBRATION
All Beck drives are set-up and calibrated to the customer specification. No electrical adjustments are required before installation. Additional features available on Beck control electronics:
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.
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.
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.
FACTORY CALIBRATION
All Beck drives are set-up and calibrated to the customer specification. No electrical adjustments are required before installation. Additional features available on Beck control electronics:
Beck’s durable gear train maintains accurate, consistent control element positioning even under the demanding conditions of an active control loop.
- Gear trains employ a unique, all spur gear construction of heat-treated alloy steels and ductile iron.
- Efficient, wide-face spur gearing virtually eliminates wear-induced backlash and positioning inaccuracies.
- Durable design provides up to 4 days of protection against intermittent or extended accidental stalls.
- Integral self-locking mechanism ensures that drives hold a load with the motor de-energized.
An easy-to-turn, spoke-free Handwheel is incorporated into the Group 22 design to allow manual operation during installation or power outages.
- Move dampers to any position smoothly and easily without power, even under full load conditions.
- Mechanical stops in housing prevent manual overtravel.
CPS-4 Compartment
Beck drives feature a cast aluminum body with individual compartments to protect components from moisture and dirt, and allow easy access for installation and calibration.
- Precision-machined aluminum alloy castings with corrosion resistant poly-urethane paint provide a rugged, dust-tight, weatherproof enclosure.
- Individual compartments protect all major components: Motor, Digital Control Module, Contactless Position Sensor, gear train, and installation wiring terminal board.
- Each compartment can be accessed without exposing other components.

CONTROL OPTIONS
Beck Group 22 rotary actuators are equipped with a comprehensive set of control electronics that allow you to position the drive with an analog signal or through contact-closure operation using the control override inputs. These units are also equipped with position feedback, torque sensing, a system alarm contact, and handswitch auto indication. This compilation of features is available in a single control option, control option 9. The resultant Group 22 rotary actuators will be model numbers 22-309, 22-409, or 22-809 only.OPTION
Control Option 9 – Typical Arrangement
CONTROL OPTION 9 – The modulating drive offering for the group 22 rotary actuator is the control option 9. Control option 9 units are equipped with the Beck DCM (Digital Control Module) and CPS (Contactless Position Sensor). The option 9 drives may be controlled with a 4-20 mA or 1-5Vdc signal and have an integral 4-20 mA position feedback signal. The microprocessor based DCM electronics packages provide a multitude of flexibility for setup, calibration, and diagnostics.
