by powering up the controller with the level 3 access button pressed and
tests can also be run at other times using the Tester web page. The tests

page. Full details on scenarios are given in the ST950 Facilities Handbook
(667/HB/46000/001) but the scenarios most appropriate to installation and
commissioning are ST950 System Test (the default which is used if no other
choice is made) and ST950 System Test (no licence).
ST950 System Test Scenario
This scenario does not require any special connections and is suitable for running
on most controllers. This is the default scenario.
