Beckwith M-0067E On Load Voltage Regulating Controller Selection and Debugging Guide

Set the center voltage and bandwidth to the target values.

Perform test mode validation and observe the relationship between LED indication and measured voltage.

Conduct actual load testing for line voltage drop compensation when necessary (observe the direction of voltage adjustment by suddenly increasing the load).

Maintenance and spare parts

M-0067E adopts solid-state circuits, with no vulnerable mechanical components, and only requires regular cleaning of the panel and inspection of wiring fastening. Its LED indicator has a lifespan of up to 25 years and is replacement free. All calibrated potentiometers are high stability models and usually do not require recalibration unless there are system changes. If replacement is required, the same model of product is still in production and can be directly replaced with the old Westinghouse SVC/SVR controller without the need for wiring modification.
