Electronics Module Produces Voltage Applied to Motor Winding

Oct. 5, 2015
Device eliminates the need for manual testing

The Automeg electronics module is a compact and completely solid-state 12-pin plug-in instrument that can be installed into new or existing control panels. The instrument is designed to produce a low-current high voltage that is applied to the motor winding. The circuit includes means for measuring leakage currents and for triggering alarms for selected levels of leakage. These alarms may be the existing high-level alarm light and horn, or they can be wired into the telemetering terminal board.

The Automeg module includes a green sunlight-visible LED display light to indicate power and a red sunlight-visible LED display light to indicate a 1-megohm motor winding leakage resistance to ground. It will automatically alarm if the motor winding leakage resistance drops to 1 megohm or less. An optional model that inhibits the motor from starting at a low meg reading is also available. A motor reset button is also included, along with a bypass switch so that the Automeg can be bypassed in the event of an emergency situation.

A manual test button to test the internal circuitry of the Automeg is a new feature of the device. Also included is a yellow LED that has been added to indicate when 500 VDC is applied to the motor windings before starting. This latest major breakthrough in preventative maintenance eliminates the need for an electrician to manually test the insulation resistance of the motors. In addition to the relatively low cost of the versatile Automeg module, savings are compounded because of the fact that motor burnouts due to moisture penetration and motor failure emergencies will be virtually eliminated, and repair work can be efficiently scheduled.
