Safety System Screen

This screen shows the safety system in table format. The rows being the causes, and the columns the sub-systems/effects. When a row is activated, the boxes corresponding to the subsystems/effects affected by that cause are coloured in. There are four different colors:

  • White: No active interlock.

  • Orange: An interlock is active. No operation by the operator is required. Once the cause is solved, it is released without resetting.

  • Red: An interlock is active. The cause of the interlock needs to be reset by the operator once it has been resolved.

  • Purple: overrides the cause for a certain amount of time (180s). The interlock reappears if the cause is not released and reset during this time.
