After cleaning the NC4 unit
1. Reconnect and switch on electrical power to the NCi-6 interface unit (for more information, see
“Supplying electrical power to the NCi-6 interface unit” on page 3-8).
2. Restore the air supply to the NC4 unit and adjust the pressure (for more information, see “Setting the
NC4 barrier air pressure” on page 3-9).
3. If realignment is not necessary, set switch SW1-2 (NC set-up) on the NCi-6 interface unit to ‘On’. After
approximately 5 seconds, set the switch to ‘Off’.
4. Check that the system triggers. To do this, pass an object through the laser beam and check that the
NC4 unit’s status LED changes from green to red and back to green.
NOTE: A mobile app (NC4 app) is available for step by step instructions on the cleaning process (for more
information, see page 3-10, “Machine tool apps”).
