Setting the air pressure
WARNING: Before setting the air
pressure, ensure the machine is safe
to work on.
1. Ensure that electrical power is applied to the
NCi-4 interface.
2. Switch on the air supply.
3. Gradually increase the air pressure until the
laser beam is seen to exit the transmitter
unit.
4. Note the pressure on the pressure gauge
and increase the pressure by an additional
0.5 bar (7 psi). Check that the profile of the
laser beam is circular.
NOTE: If the air supply pressure varies while the
machine is operating, the air pressure to the NC4
system may need to be increased to allow for
this pressure fluctuation.
