Servicing – NC4 fixed system
Disassembling and
reassembling a fixed system
The NC4 fixed system can be partially
dismantled to allow air lines to be replaced and
gain access to the PassiveSeal.
Before disassembling and reassembling the
units, ensure that swarf and debris is removed
from the system.
The following procedures are suitable for the
transmitter and receiver units.
Disassembling
WARNING: Before disassembling the
fixed system, ensure the machine is safe
to work on.
Remove power and air from the NC4 system.
CAUTION – LASER SAFETY
The access panel of the NC4 transmitter
unit might be removed when disassembling the
fixed system.
Before disassembling the system, switch off
electrical power to avoid exposure to the laser
beam.
1. Switch off the electrical power to the NCi-4
interface.
2. Remove the air supply from the NC4 by
setting the pressure regulator to 0 bar.
3. Remove the two M4 rotation holding screws.
Do not lose the plain washer and disc spring
that are fitted under each screw head.
4. Slacken the two rotation adjuster screws.
5. Carefully pull the NC4 unit assembly out of
the housing so that the mounting block is
exposed.
