Switch Operation 0
This rugged, completely self-contained NEMA-4 switch is a rotary shaft speed detector and tachometer. It will electronically detect either underspeed or overspeed. This is accomplished by set-point selection done directly thru pushbuttons and is displayed on the LCD readout. The actual shaft speed can be displayed on the LCD by a simple push of a button.When the shaft speed on a piece of equipment exceeds or falls below the set-point speed, change is immediately detected and output is provided via relay contacts to actuate motor contactors, audible alarms, warning lights, PLC's etc. Maximum response time is the time required to rotate 1/16 of a turn at the set speed for a standard unit, or 1/60 of a turn for the high response option, after the shaft passes through the set speed. The output condition is displayed as "ON" or "OFF". When "ON" is displayed, the driven speed exceeds the overspeed setpoint, or is below the underspeed set-point. The output relay is de-energized in this condition and the "Alarm" contact (N.C.), closed in the output relay. The ESS also falls into this condition under loss of power providing the logic that indicates "Alarm" under power failure to the ESS.
