Operation of the Festo Training System
Festo training systems have been designed for ease of use by both the student and the in-
structor.
Compressed air should be handled with respect. Care should be taken to ensure that com-
pressed air is not directed at open cuts or against the skin, since serious physical damage
and/or dangerous embolism may result.
Compressed air should be applied to the service unit at the port next to the regulator/filter.
Air service for the automated system is drawn from the right side of the service unit. The ser-
vice unit is fitted with a normally closed 3/2 directional control valve with a red knob. The
valve is opened to provide air to the manifold by moving the knob in line with the direction of
airflow. All connections should be made with this switch turned off.
All pneumatic components are fitted with quick-connect air line fittings. Tubing to be con-
nected to these fittings should be cut squarely. Tubing is pushed into the fitting until a resis-
tance is felt; this is a metal ring. The tubing is pressed further until it stops. The tubing is
then checked by pulling gently back on the tubing. Leaks at the quick-connect fittings may
sometimes be traced to failure to fully set the tubing in the fitting. Another common cause of
air leaks may be a tubing end not cut at a shallow angle or tubing, which has become worn
and ragged through use. These tubing faults may be corrected by cutting a short section
from the end of the tubing to expose a fresh surface.
The instructor should check the connections on the circuits to ensure that the tubing is se-
cured properly before the circuits are pressurized. Compressed air escaping to atmosphere
from a loose and uncontrolled tube will cause the tube to whip, therefore safety glasses
should be worn whenever students or instructors are working or observing any of the auto-
mated systems.
