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 250 mA.
If the circuit has been overloaded, the fuse may have
blown. See internal diagram on page 21 and replace 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.
1. Valve operating pressure lower than 60 psi (4.1 bar)
can cause inconsistent output. Check to be sure
pressure is set at 70 psi (4.8 bar).
2. Check VALVEMATE
™
7040 and reservoir air pres-
sure readings to be sure air pressure is not varying.
3. Air bubbles in the material can cause inconsistency.
For best results, remove all air bubbles.

Note: The EFD timer is very reliable. Any failure will be total,
so that no inconsistency is possible. Most questions regarding
the timer are resolved by simply turning the time override
mode off.
