Monitor Operation Summary

The 1900/27 Vibration Monitor provides continuous vibration monitoring for machinery. It utilizes a transducer to measure shaft vibration transmitted to the case, serving as a key indicator of overall mechanical condition. The monitor can detect various malfunctions like imbalance, misalignment, and bearing wear. It features a digital LCD display for overall vibration or setpoints, status LEDs for OK, alarm, or bypass conditions, and a remote reset option. Programmable features include relay behavior (latching/non-latching, energized/de-energized), time delays for alarms, alert relay configurations, and unit selection (English/Metric). The monitor also includes a self-test function for troubleshooting.
