Supplying electrical power to the NCi-6 interface unit
WARNING: Before switching on electrical power, ensure that the machine is safe to work on.
1. Ensure that the NCi-6 interface unit and air supplies have been connected correctly (see the table
above for further information).
2. Switch on electrical power to the NCi-6 interface unit.
3. Check that the status LEDs on the NC4 transmitter and receiver heads are lit.
What to do next
When the NCi-6 interface unit is powered up, switch on the air supply and set the correct air pressure (see
page3-9, “Setting the NC4 barrier air pressure”, for further information).

If electrical power to the NCi-6 interface unit is lost and subsequently restored when the NC4 system is
