Troubleshooting
Problem Possible Cause and Correction
LED is blinking “ALr”
and
will not accept initiate signal.
Air pressure to the solenoid pack has
dropped below 4.1bar (60psi) or if low level
float switch is used, tank level is low. Raise
the input pressure to 4.8bar (70psi) or refill
the tank. Press CYCLE
button to reset.
If problem persists, make sure devices such
as air cylinders are not causing a pressure
drop in the ValveMate 8040 solenoid pack
input air line. If no ALARM switch is being
used, the ALARM IN + / - terminals must have
a jumper installed to disable ALARM feature.
Unit is not responding to the
initiate signal.
Check to make sure the unit is not in a mode
other than RUN
. Response delay in
pneumatic circuit does not allow the valve to
open when time is set at or below 0.010
seconds. Increase time. Initiate signal may
have a low level of leakage. The signal must
break clean before the next signal is initiated.
Timer is inoperative. Check to make sure the unit is not in the
steady mode. The timer is very reliable. Any
failure is total so no inconsistency is possible.
Flashing
on LED display.
Short on the OUT TO SOLENOID circuit.
Check solenoid wiring connections.
