Testing Before Installation

If the SST Switch 3D Gun has been assembled after a
major repair or maintenance operation, it is
recommended to perform a function test before the SST
Switch 3D Gun is returned to production.
A minimum level of function test is to connect the
compressed air supply and check for air leakage by
opening each of the solenoid valves (613) manually.
The cable connections can be checked using an
Ohm-meter to test the connections from the plug to the
terminals and to make sure that there are no
short-circuits.
If the SST Switch 3D Gun is tested offline with
material pressure applied, to avoid skin injection
always keep clear of the nozzles when test spraying.
Make a last check on all assembly screws and then
follow the Installation instructions on page 8 to mount
the SST Switch 3D Gun on the robot.
