Installation
3A5591D 15
Before installing the spray nozzles (BC), it is important
to check that the nozzle gaskets (BD) are in their correct
positions. The nozzles must be inserted in the nozzle
cap (BA), then the nozzle cap with the nozzles must be
firmly fixed to the nozzle head (BB) using the M6 hex
button head screw (BE) in the center of the cap.
When the applicator is fixed in the correct position the
electrical cable can be connected. First connect the
cable to the applicator, then install the cables to the
robot and make the appropriate connections in the con-
trol cabinet.
See the appropriate Repair-Parts manual for your appli-
cator model. See
Related Manuals on page 2.
The air supply is connected to the applicator with a 8
mm PU-hose to the push-in coupling on the side of the
swivel housing.
The material supply hose is connected to the connection
point “Inlet”. The material return hose is connected to
the connection point “Return”. If circulation was not
selected, the return connection is plugged. If dual mate-
rials are supplied, both connections are inlets (no return
possible).
After completion of the installation of hoses and cables,
there 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.
Test for Leaks
With the applicator properly installed on the robot, the
functions of the unit can be tested. First open the air
supply. There must be no sound from leaking air.
Check that the solenoid valves are working properly by
open and closing each valve from the robot pendant and
listen to the sound of the piston in operation.
Apply material supply pressure and check for leakage.
Move the applicator to the purge position and purge all
nozzles one by one until the unit is completely filled up
with material and all entrapped air is removed from the
supply system.
Open the circulation valve and purge the material
through the dump valve until all entrapped air in the
material return is removed.
