| MODEL 269R Over & Under 3-Phase Monitor |
| Series Description: The Model 269R Over & Under 3-Phase Monitor continuously monitors 3-phase lines for high voltage, low voltage, phase loss or phase reversal, and an adjustable . 3 5 minute restart delay. This device features a solid-state voltage and phase angle sensing circuit, which drives a SPDT output relay. The Model 269R is independent of the system load, and may be used on any horsepower motor. When phase sequence is correct, and the voltage remains between the upper and lower trip points, the output relay remains energized. When a fault condition is sensed, the output relay drops out. The Model 269R does not require a neutral connection, and can be used on Wye or Delta systems. Each of the four voltage versions can be adjusted over a wide range. An adjustable restart delay (0.3-5 minutes) allows compressor head pressures to bleed off, in the event of short-term power failures. OVER and UNDER voltage failure indicators aid in cali bration and system troubleshooting. |
