Relay boxes control access to machines that need inductions.

If you are inducted to use a machine, you can use your keycard to unlock the Relay Box, which will power up the machine.

The relay boxes also report live usage information to our Tool Status page, so you can see which machines are in use at any time.

As shown above, a relay box includes an the following: * An Indicator Lamp - shows whether the connected machine is powered. If the lamp is on, the machine has power. * A Status LED - shows whether the control box is ready to use, has an error, etc. * A Button - powers down the machine and logs you out. * A NFC Sensor - reads your keycard.

By default, the Status LED should be slowly pulsing. This means the machine is not powered, and it is waiting to read a keycard.

To Log in, tap your keycard on the NFC Sensor.

If your are inducted to use the machine, the Status LED will go out, and the Indicator Lamp will come on to show the machine is powered.

If you are not inducted, the Status LED will flash for a couple of seconds.

Once you have finished using the machine, switch it off, then press the Button on the Relay Box to log out. The Indicator Lamp will go out to indicate the machine is no longer powered.

Some Relay Boxes will automatically log out if you don't use the connected machine for more than 20 minutes.

If the Relay Box you wish to use it not accepting your card:

• First: Try your card away, waiting 5 seconds, then tapping again.
• Second: Try turning the machine off at the wall and on again. The Relay Box will take a few seconds to reboot and the Status LED will start pulsing when it's ready.
• Third: Check you are inducted using the Kiosk. For some tools, the online self-inductions expire after a set period and need to be taken again.
• Forth: Check the status page for one of the following messages alongside the relevant tool:
  • 'INITIALISING' or 'OFFLINE' - it has likely lost it's network connection - try turning it off at the wall, waiting a few seconds, then and turning it on again.
  • 'MAIN' - 'ACCESS' - double check your induction status. If this is valid it is likely that the box has been configured as the wrong machine. Contact the Committee.
  • 'PN532' - push the logout button and wait 5 seconds before retrying. If this fixes your issue please contact the Committee. The NFC reader will likely fail completely soon.
  • 'WAITING' - push the button, the status should return to AVAILABLE you should now be able to login.
