	Description The ZSU speed controller is a monitor for rotating or oscillating machine parts. The speed controller continuously compares the set speed with the actual speed and produces a switching output when excessive speed variation occurs. The actual speed is monitored by a non-contact sensor on the machine itself. Advantages control of speeds above and below the set speed 230V AC or 24V DC Power voltage free DPDT relay LEDs indicate state of operation adjustable start up delay adjustable hysteresis programmable working current or static current Usable Sensors 3 wire, PNP or NPN 2 wire magnetic proximity sensors limit switch inductive, magnetic, or capacitive proximity switch photoelectric reflex, proximity, or through beam sensor Speed Adjustment The speed is adjusted by the potentiometer "Imp./min."(pulses per minute) and by the three-step slide switch. So in the three steps, the speed ranges 5-50 (x1), 50-500 (x10), and 500-5000 (x100) pulses per minute are reached. Hysteresis Hysteresis is defined as the difference in speed between the relay switching on and off. Hysteresis to the low speed switching point can be adjusted by the potentiometer "Hysterese%" from 5% to 100% (hysteresis factors 1.05 to 2.0). Start Delay After start up, a motor will not be at its rated speed for some seconds. To avoid an unwanted alarm, this time can be adjusted up to 15 seconds. The time can be adjusted by the potentiometer "Anlauf/sec." or by connecting an external resistor.
