LA70 and LA70M Range Limiters TM70 Radio Remote Controls
Introduction
System Description
TM70 radio remote control systems can be equipped with a range limitation option for applications where the operator has to be in a particular place for safety. One example can be on overhead cranes. When away from the working area, it deactivates the movement controls while maintaining the radio communication.
The system consists of one or more Infrared transmitters LA70, installed either in fixed positions or on the controlled machine, oriented in such a way that it covers the targeted working zone. In this case the remote control transmitter is equipped with a sensor which receives the information coming from the LA70 transmitter. This information is analyzed by the transmitter and determines if the operator has left the working area. Consequently, outputs are deactivated.
