ROTATION CONTROLS

Product catalog summary
Overview: The document provides detailed information on the CRT Series Electronic Rotation Control devices, including their working principles, programmable functions, and specific models such as CRTP and CRT30. These devices are designed to monitor the time interval between signals in rotating or cyclic mechanisms, alerting users to any decrease in speed or stoppage.
Working Principle: The devices function by measuring the time gap between signals detected by a sensor. If this time exceeds a preset value, the device signals a slowdown or stop. They are available with either independent control units or integrated sensors, making them suitable for applications like conveyor belts, elevators, and mixers.
Programmable Functions:
  • Time and RPM: The time range is adjustable from 0.03 to 512 seconds across nine scales, selectable via dip switches. RPM conversion is also possible.
  • Function A-B: Two operational modes are available. Mode A requires power cycling or reset to reactivate, while Mode B reactivates automatically with the first sensor impulse.
  • Sensor Selection: The device supports NAMUR, NPN, and PNP sensors, selectable via a switch.
  • Rotation and Shaft Standstill Control: Two modes are available: Rotation Control (relay deactivates on no impulse) and Shaft Standstill Control (relay activates on no impulse).
Model Specifics:
  • CRTP: Offers a wide range of sensor compatibility and programmable RPM from 0.1 to 2400 Imp./min.
  • CRT30: Features a cylindrical sensor with a 4-6 mm detection range, suitable for compact installations. It supports RPM ranges of 6-150 and 120-3000, with automatic reactivation in Mode B.
Technical Characteristics: The document provides detailed specifications, including working distance, voltage requirements, detectable RPM range, response time, and environmental limits.
Sensor Overview: The document also covers technical specifications and operational guidelines for various types of sensors, including capacitive, photoelectric, Hall effect, and others, with a focus on the CRT30 series, which are inductive rotation control sensors.
Specifications: CRT30 sensors are designed to control the time interval between signals in rotating or cycling mechanisms. They operate with a multivoltage power supply ranging from 18-50 Vdc and 18-240 Vac. The sensors have adjustable RPM ranges from 120 to 3000 and feature a changeover relay output activated under normal conditions.
Features: The sensors include a yellow LED for target detection and a red LED for alarm indication. They are housed in a metallic cylinder with dimensions M30x1.5 and are made of nickelled brass. The sensors are suitable for environments with temperatures ranging from -20 to +70°C and have an IP rating of 67.
Functionality: The device measures the time gap between signals. If the gap is smaller than the preset value, it signals an increase in speed. If the gap is larger, the device maintains its state, allowing normal operation. This functionality is crucial for applications requiring speed monitoring in rotating units.
Installation and Usage: The document includes wiring diagrams and installation instructions to ensure correct setup. The sensors are programmable via DIP switches, allowing customization of operational parameters.

Quando l'intervallo di tempo rilevato è superiore a quello prefissato sul dispositivo, lo stesso interviene commutando il suo stato segnalando così l'eventuale diminuzione di velocità o fermata dell'unità rotante o ciclica. Se invece arrivano...
