Trouble
Possible cause and correction
Be sure that there is power at the wall
receptacle. Check the input power fuse.
If the fuse has blown, check the voltage
value in the fuse cartridge window. Be
sure that it matches the input voltage.
Ensure that the external voltage to the
circuit is between 5 and 24 VDC and that
the load does not exceed 250mA. If the
circuit has been overloaded, the fuse may
have blown. Replace fuse, if necessary.
Response delay in pneumatic circuit does
not allow the valve to open when time is
at or below 0.015 seconds. Increase time.
Valve operating pressure lower than 60 psi
(4.1 bar) can cause inconsistent output.
Make sure pressure is set at 70 psi (4.8 bar).
Check controller and reservoir air pres-
sure readings to be sure air pressure is
not varying.
Air bubbles in the material can cause
inconsistency. For best results, remove all
air bubbles.
Check to be sure time override mode is off.
