C269 - Time Mark

The Model 269 Over and Under 3-Phase Monitor Continuously Monitors 3-Phase Lines For High Voltage, Low Voltage, Phase Loss or Phase Reversal. This Device Features A Solid-State Voltage and Phase-Angle Sensing Circuit, Which Drives A SPDT Output Relay. The Model 269 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 Energizes. When A Fault Condition Is Sensed,

257B - Time Mark

The Model 257 Continuously Monitors 3-Phase Power Lines For Abnormal Conditions. When Properly Adjusted, The Model 257 Monitor Will Detect Phase Loss On A Loaded Motor Even When Regenerated Voltage Is Present. This Device Consists Of A Solid-State Voltage and Phase-Angle Sensing Circuit, Driving An Electromechanical Relay. When 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 Autom
