WARNING DANGEROUS VOLTAGES, capable of causing death or serious injury, are present on the external terminals and inside the equipment. Use extreme caution and follow all safety rules when handling, testing or adjusting the equipment. However, these internal voltage levels are no greater than the voltages applied to the external terminals.
PRODUCT CAUTIONS Before attempting any test, calibration, or maintenance procedure, personnel must be completely familiar with the particular circuitry of this unit, and have an adequate understanding of field effect devices. If a component is found to be defective, always follow replacement procedures carefully to that assure safety features are maintained.

M-2067B Adapter Panel – Specification The M‑2067B is an adapter panel which, when combined with the M‑2001 Series Digital Tapchanger Control, provides convenient direct replacement for Westinghouse SVC and SVR controls and Beckwith Electric M‑0067 series controls. The M‑2067B can also be used, with the M‑2001 Series Tapchanger Control, as a general purpose LTC transformer control.
M-2067B Application Guide Introduction The Beckwith Electric M‑2067B Adapter Panel, used in conjunction with the M‑2001 Tapchanger Control, uses modern electronic digital design and digital processing circuitry to achieve an overall stability and resolution unattainable with electromechanical and analog design tapchanger controls. CMOS semiconductors are used throughout the design.
M‑2067B Application Guide Load current must be reduced by an appropriate auxiliary current transformer to 0.2 A "full scale" before connecting to the M‑2067B current inputs. The Beckwith Electric M‑0121 (5.0 A to 0.2 A) or M‑0169A (5.0 A or 8.66 A to 0.2 A) Auxiliary Current Transformer can be used for this purpose. The M‑0121 can be used with Beckwith Electric Tapchanger Controls when the only burden present is the Line Drop Compensator circuit of the voltage regulating relay.
M-2067B Application Guide Multi‑Step Voltage Reduction On the M‑2067B, TB1‑11 and TB1‑12 on the printed circuit board are used together to provide up to three levels of voltage reduction. The external connections to achieve these steps are shown in Figure 1 Figure 2 Table 1.

M-2067B Application Guide Use of the M‑0329B LTC Backup Control with the Tapchanger Control The M‑0329B is a single‑phase, solid‑state backup control that prevents a defective tapchanger control from running the voltage outside the upper and lower voltage limits. The Block Raise and Block Lower voltage levels are set by accurately calibrated dials.
M‑2067B Application Guide Installation The M‑2067B is a general purpose adapter panel that is designed for mounting in a 5‑7/8" x 15‑1/8" panel cutout. Remove the old control from the cabinet. Refer to Figure 8 for outline dimensions; refer to Figure 9 for panel cutout dimensions of the M‑2067B.
