Specications
The Model 80
is designed to continuously monitor phase rotation
of 3-phase systems. Critical applications include
fan motors, scroll compressors, grinders, conveyor
systems, elevators and escalators. A solid-state
phase-sensing circuit drives an internal electro-
mechanical relay which is energized when proper
phase rotation is applied. An LED indicator
illuminates when phase rotation is correct. Reset
is automatic.
For more information see:
See Appendix A, page 68, Figure 6 for dimensional
drawing.
See Appendix B, page 73, Figures 8 & 9 for typical
wiring diagrams.
