Fault
Possible cause
Remedy
Output A not exhausted inspite of both
buttons being pressed within < 0.5 sec.
Input pressure too high
Reduce input pressure at P
1
and P
2
Tubing for finger lever valves
not of equal length
Cut tubing for finger lever valves to equal length
Output A pressurized in spite of:
- actuation time of both buttons > 0.5 sec.
- one button being released
- only one button pressed
Input pressure too low
Increase input pressure at P
1
and P
2
to
at least 3 bar
Functional fault
Return to Festo
Reduction of pressure at output A lasts too
long.
Fault in tubing
Use short tubing; avoid angled screw connections
Air comes our of R when both finger lever
valves are actuated
