Relay Box

This is the guide for the relay / tool power access control boxes.

The guide for the doors is available here: https://wiki.bristolhackspace.org/access_control/door

The boxes are controlled by a NFC card reader towards the bottom of the box and a button at the top of the box.

The red status LED displays the controller state and the orange indicator lamp shows the power is provided to the tool.

When a box is locked and ready to go the status LED will “breath” changing from low to high brightness over a couple of seconds.

Tap your card or fob on the NFC sensor towards the bottom of the box over the “N” logo in the diagram above. The box will check with the induction system that you have the required inductions to operate the machine and turn on the power to the tool. The status led will turn off and the indicator lamp will turn on. If the box can not reach the induction system or the required inductions have not been completed (or have expired) the red status LED will flash three times. Occasionally an invalid or corrupt value may be read from the NFC, take your card away from the NFC sensor for five seconds then retry.

When the status lamp is on you can use the tool.

When you have finished with the tool press the button to log out.

Some tools (mostly woodshop saws) will automatically log out if not used for more than 20 minutes.
