Description

The XPS-VN safety relay is used for zero speed detection of electric motors. Its primary use is in systems requiring the reversing of a motor and for unlocking doors and guards with safety interlocking devices. When coasting to a stop, electric motors generate a residual voltage in their windings, resulting from residual magnetism, and this decreases proportionally to the decrease in motor speed. This residual voltage is monitored by the XPS-VN safety relay to detect the motor’s zero speed. The wiring between the motor windings and the safety relay are also monitored, to identify a wire break (fault) differently from a zero speed detection. The XPS-VN safety relay is designed for zero speed detection in all types of electrical machinery using DC or AC, single phase or three phase power, which can be controlled by electronic motor controls such as adjustable frequency controllers, control components to start under low load (ie: low voltage), and brakes which inject direct current (DC) into the windings. When using electronic motor control equipment, refer to the paragraph ”Use of electronic motor control”.
