Hose Connections
The air supply is connected to the Switch 3D Gun with
an 8 mm polyurethane hose to the elbow swivel fitting
(620) on the side of the swivel housing (619). Customer
must install air bleed valve between air supply and
Switch 3D Gun connection. See F
IG
. 6.
The material supply and return hoses use 3/8 BSPP
connectors. The material supply hose is connected to
the port marked “Inlet”. The material return hose is
connected to the port marked “Return Inlet 2”. (If no
circulation is selected, the Return Inlet 2 port is plugged
with a 3/8 BSPP plug (132879). If dual materials are
selected both connections are inlets (no return
possible). See F
IG
. 6.
Check for Free Movement
After completing the installation of the hoses and
cables, the free movement must be checked by moving
the fifth axis of the robot. The hoses and cables must be
able to move freely without stretching or scratching the
robot arm.
Flush Switch 3d Gun Before Using
The Switch 3D Gun was tested with lightweight mineral
oil, which is left in the fluid passages to protect parts. To
avoid contaminating your fluid with oil, flush the Switch
3D Gun with a compatible solvent before using.
Leak Test and Priming for Use
After the Switch 3D Gun is completely installed on the
robot, the Switch 3D Gun can be tested for leaks. This
procedure also primes the Switch 3D Gun for use.
a. Open the air supply. There must be no sound
from leaking air.
b. Check that the solenoid valves (613), shown on
swivel chamber parts page 28, are working
properly by opening and closing each valve
from the robot pendant and listen to the sound
of the piston in operation.
c. Apply material supply pressure and check for
leakage.
d. Position the Switch 3D Gun into a grounded
metal pail and purge all nozzles one by one until
the unit is completely filled with material and all
entrapped air is removed from the supply
system.
e. Open the customer supplied recirculation valve
and purge the material through the valve until all
trapped air in the material return is removed.
