D2644M
The Model 2644 3-Phase Monitor continuously monitors 3-phase Wye or Delta systems for abnormal conditions.The solid-state electronic sensing circuitry drives an internal DPDT relay, allowing the Model 2644 to operate two motor control circuits, or a control circuit and an alarm circuit. An adjustable trip delay reduces or eliminates nuisance tripping caused by momentary voltage fluctuations on motor start-up. An optional restart delay gives approximately a 3.5-minute delay when the relay drops out, to allow compressor head pressures to bleed off, in the event of short-term power failures.
Voltage adjustment ranges are sufficiently wide to allow for proper calibration to existing conditions. Both TRIP and NORM indicators are provided to aid in adjustment and system troubleshooting. Automatic and manual reset versions are available. The Model 2644 Monitor is not sensitive to line current, and can be used with any size motor or compressor.

EX2642
The Model 2642 protects electrical equipment by sensing phase loss, low voltage and reverse phase conditions. The monitor uses a combination of voltage and phase-angle sensing, and will detect a phase loss even when regenerated voltages are present.The Model 2642 is fail safe; the output contacts will transfer when correct power is applied, and trip out on any fault condition or complete loss of power. Each of the five voltage versions can be adjusted throughout a wide operating range. An adjustable trip delay timer prevents nuisance tripping caused by momentary voltage dips. LED indicators show NORMAL (green) and TRIP (red) status.
The Model 2642 has an automatic reset which can be converted to manual reset with the addition of a normally closed switch. The DPDT out put can be used in motor control circuits and/or alarm circuits.
