BWI Eagle, 11-7100, Optima 2 Dual Channel Speed Switch with First Out Indicator
Features:
- The OPTIMA 2, Model 11-7100 monitors speed and detects motion in all types of rotating electrical apparatus.
- Two independent channels allow a variety of control functions to meet virtually any application requirement for under-speed or zero-speed detection from 6 RPM up to 800 RPM.
- Its rugged NEMA enclosure is well-suited to meet the environmental challenges of any industry.
- Ideal for conveyors, crushers, fans, motors, and other rotating apparatus.
The EAGLE OPTIMA "First Out" capability enables the user to visually see (by an LED indicator) if the slip switch relay contacts were the first to open. Once the belt is running and the control relay in the OPTIMA unit has energized, the First-Out indication (if activated) will extinguish. If the belt begins to slip and the OPTIMA unit shuts the drive down, the First-Out LED will illuminate. This LED will stay lit until the belt is restarted and the control relay in the Optima has energized. If R1, R2, or R3 would open, this would shut the drive down, and also the slip switch contacts would open. But, the First-Out LED would not be illuminated. This would allow the user to see that the slip switch relay contacts were not the first to open and cause the shutdown.
