INSTALLATION WIRING The Group 14 drive is available with six separate control configurations which are provided to match the control requirements for your system. Typical functional wiring connections for each control option are described in the following paragraphs and diagrams. The wiring diagram specific to each drive is attached to the inside of the wiring terminal cover.

INSTALLATION WIRING Option 8, Modulating without External Feedback Signal Analog Position Control with Contactless Position Sensing Customer must supply two wires to power the drive: One 120 V ac line (terminal C), and one neutral (terminal B). Customer must supply two wires for the modulating analog control signal: Connect to terminal AA (+) and to terminal BB(-). Option 7, Modulating Analog Position Control with Potentiometer Position Sensing Customer must supply two wires to power t

Option 4, Multi-Position Direct AC Control with Cam-Operated Switches to Stop Drive Travel Customer must supply three wires to directly control the drive motor direction: One 120 V ac line for Retraction (terminal M), one 120 V ac line for Extension (terminal N), and one neutral (terminal B). Up to five intermediate stop positions may be specified, each requiring an additional 120 V ac line. Option 3, Open / Close Direct AC Control Customer must supply three wires to directly control

INSTALLATION WIRING OPTIONS Split Range Operation Two or three Beck drives may be operated over their full range by a portion of the controller’s output signal range. The most common arrange- ment involves two drives operating on equal halves of the input signal range. For example, if a 4–20 mA control signal is used, the first drive would move 100% of its stroke on a signal range of 4–12 mA, while the second operates on the 12–20 mA portion of the signal. In this case, the ESR-4 boar

OPERATION INPUT: ESR-4, CONT’D. POSITION FEEDBACK: CONTACTLESS POSITION signal. The difference between these signals— the error—is amplified and used to actuate either SENSOR (CPS-2) of two electronic motor power switches. These The CPS-2 provides a continuous feedback switches drive the motor in the proper direction signal proportional to the position of the drive’s to force the error to zero. The input signal is output shaft. It is used for remote position adjustable from 50% to 4
