PS111 ZERO-SPEED SWITCH
Operating Logic:
Upon application of power to the input, the internal relay is energized and a time interval starts. If there is motion being sensed, pulses will be present at the sensing input, and the timer will be reset on each pulse. If pulses are coming at a rate faster than the time interval set by the potentiometer, the relay will stay energized. Should motion stop, the unit will time out and de-energize the internal relay.
Adjustment:
Easily adjustable linear scale, locking bushing potentiometer
Standard Time Ranges:
0.05-5 sec., 0.3-30 sec., 1.8-180 sec. Other ranges on special order
PS112 ADJUSTABLE SPEED SENSOR
Operating Logic:
Upon application of power to the input terminals, the PS112 begins sensing the repetition rate of the pulses being generated by the proximity switch. If the pulse rate is lower than the set-point adjustment, the internal relay remains deactivated. If the pulse rate is higher than the setpoint, the internal relay acti-vates.
Sensing Range:
150 to 1500 PPM, standard. Other ranges on special order.
Response Time:
Equal to time between any two pulses at given setpoint.
Adjustment:
Easily adjustable linear scale, locking-bushing potentiometer.
