Harold-Beck - Model 11-150 -Rotary Damper Drives and Actuators
Group 11 rotary damper drives and actuators offer the benefit of a total control package, utilizing reliable electronics to match the speed and precision of your process instrumentation.
Standard Group 11 modulating drives (control option 9) are equipped with Beck’s Digital Control Module (DCM), 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 (CPS)).
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.
Beck’s DCM-3 provides modulating control of the drive in response to standard control system signals.
Notable features include:
- Convenient user interface for calibration and drive status.
- HART® compatibility.
- Compatible with common asset management systems.
- Receives control signals directly, eliminating the need for contact protection devices, relays, switches and reversing starters.
- Designed to operate continuously at temperatures from -40º F to 185º F (-40° to 85° C).
- Initiates shaft movement in steps ranging from 0.10% to 0.25% of span, depending on the timing of the gear train.
Beck’s patented CPS-5 technology has been providing reliable control feedback with infinite resolution in our products for many years.
Notable features include:- Utilizes a unique ferrite magnetic design with no contacting or wiping surfaces to wear or intermittently lose contact.
- The ferrite rotor is driven directly by the output shaft through anti-backlash gearing.
- A 4–20 mA position feedback signal is available for remote indication.
The analog Electronic Signal Receiver (ESR-5), which is standard in control option 7 and control option 8 drives, is an alternative to the intelligent, digital control module. The timeproven ESR provides the same excellent drive control but lacks many added setup, operating, and diagnostic features afforded by the DCM-3.
WHAT IS A CONTROL OPTION?
Group 11 Beck drives have a model number such as 11-150, 11-160, 11-200, 11-260, 11-300, 11-360, 11-400, 11-460, or 11-430. Each of these drives has the capability to be equipped with different electronics combinations, which are called control options. The control option number will replace the last zero in the model number when specifying a drive model and control option. For example, a model 11-400 drive that is setup to use the control option 9 electronics would be considered a model 11-409 drive. A basic description for each control option is provided below. For details on the electronics components, please visit the Group 11 Electronics section.
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 11 design to allow manual operation during installation or power outages.
- Move valves and dampers to any position smoothly and easily without power, even under full load conditions.
- Mechanical stops in housing prevent manual overtravel.
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 corrosionresistant poly-urethane paint provide a rugged, dust-tight, weatherproof NEMA 4X enclosure.
- Individual compartments protect all major components: Motor, DCM, CPS-2, gear train and installation wiring terminal board.
- Each compartment can be accessed without exposing other components.
