Protection systems

In many industries, people have to work hand-in-hand with machines. In recycling centres, for example, segregated materials are pressed into bales. A workplace with a high safety risk for employees.

Far too often, accidents at work result in serious or even fatal injury. Employees enter danger zones, become incapacitated and the process cannot be stopped in time. Standard rip cord systems cannot prevent the unthinkable in these cases unlike the personal protection system U-Tech PRESS , which is based on state-of-the-art RFID technology. An electronic system, which, in conjunction with a transponder worn by the employee, causes the machinery to shut down as soon as he or she enters the hazardous area. Contact-free and absolutely reliable.

 

The system components

Personal protection modules

The PSM personal protection module is a small transponder, which the employee wears, depending on the model, on the wrist, in a helmet or in a pocket.

Antenna module

The ANM antenna module is mounted on the machine and defines the desired danger zone with the help of an electromagnetic field.

Self-test module

The ETM self-test module mounted on the machinery constantly monitors the stability of the electromagnetic field thereby ensuring that the system is working perfectly.

Control unit

The ALM control unit monitors all incoming pulses and triggers an automatic shutdown of the machine when the danger zone is entered or if a malfunction such as a UHF receiver failure occurs.

PSM tester

The independent PSM test module is located at the entrance to the production hall so that every employee can test the functionality of his or her PSM before starting work.

Should an employee enter the hazardous zone wearing his or her personal safety module, the control unit initiates an automatic shutdown of the machine. This system is unlike other safety systems in that activation of the PSM is possible in three directions, perpendicular to each other. This means that even if the person is buried under materials, the antenna module detects that the danger zone has been entered and switches off the machine. The system additionally monitors itself by continuously monitoring pulses of the ETM and the control unit.
