The Time Mark 158B 3-Phase Monitor continuously monitors 3-phase power lines for abnormal conditions. When properly adjusted, the unit will detect phase loss on a loaded motor even when regenerated voltage is present. The model 158B offers 208/240VAC input voltage, 160-260VAC adjustment range, 60Hz frequency, and .5W power consumption. This device consists of a solid-state voltage and phase-angle sensing circuit, driving an electromechanical relay. When the correct voltage and phase rotation are applied, the internal relay will energize. A fault condition will de-energize the relay. When the fault is corrected, the monitor will automatically reset. The Model 158 series does not require a neutral connection and can be used with Wye or Delta systems. Voltage ranges are sufficient to allow for proper adjustment to existing conditions. A front-mounted LED failure indicator is provided.
