Radio Frequency (RF) Diagnostic Coverage For Wireless Proximity Stop Systems And Corresponding Methods Of Operating Wireless Proximity Stop Systems

A wireless Proximity Stop system comprising:

• one or more Machine Safety Devices (MSDs) each configured to be coupled with or integrated to a machine stop circuit for stopping operation of a connected machine when a Proximity Stop function is triggered, each MSD including a wireless communication interface with Diagnostic Coverage (DC);
• and
• one or more Personal Safety Devices (PSDs) each including a wireless communication interface with Diagnostic Coverage (DC) for wireless communication with the one or more MSDs, each PSD configured to be operable for initiating and safely terminating a Proximity Stop signal to the one or more MSDs to trigger the Proximity Stop function for stopping operation of the connected machine(s);
• wherein:
• each PSD includes a transmitter and separate receiver operable for verifying that the transmitter is transmitting with the correct data and power level;
• and
• each MSD includes a receiver and a separate transmitter or local transmitting beacon usable by the receiver for verifying that the receiver is capable of receiving with the correct data and power level.
