Prevention of Unauthorised Use (Unauthorised Use Prevention)
This is the set of measures that prevent an untrained or unauthorised person from operating the machine with the wireless remote control. Pairing by identity code, key-operated or code-protected activation, and physical storage discipline for the transmitter all serve this purpose.
The greatest convenience of a wireless remote control is that it is portable; its greatest weakness is the same thing. Unlike a push-button box locked to the panel, the transmitter can be forgotten on a bench, handed over to another shift, or lost.
- Technical layer: each transmitter-receiver pair is matched by its own identity code; the command of a device whose code is not recognised is not processed.
- Authorisation layer: a key switch or activation code ties switching the device on to an authorised person.
- Organisational layer: numbering the transmitters, issuing them against signature, and putting them in a locked cabinet at the end of the shift.
When a transmitter is lost, the first thing to do is to delete that device's identity from the receiver's memory and re-teach the remaining transmitters; otherwise the lost device can still operate the machine when it comes within range. In AXI sets the teaching operation appears in the product data as the teaching procedure; apply the steps from the user manual.
