Troubleshooting
Problem
Possible Cause and Correction
LED toggles between air and pressure value and
will not accept initiate signal.
Air pressure to the ValveMate 7100 has dropped
below 4.1 bar (60 psi). Raise the input pressure to
4.8 bar (70 psi). Press the Mode button to reset.
If problem persists, make sure devices such as air
cylinders are not causing a pressure drop in the
ValveMate 7100 input air line.
Unit is not responding to the initiate signal.
Check to make sure the unit is not in a mode
other than RUN. The response delay in the
pneumatic circuit does not allow the valve to open
when the dispense time is set at or below 0.010
seconds. Increase dispense time. The signal must
break cleanly before the next signal is initiated.
Timer is inoperative.
Check to make sure the unit is not in the steady
mode.
