start on
recirculation or
injection
command 1. Air supply too low Ensure air supply at least 6 bar
(90psi)
2. Pump speed set too
low Set at least to 1 bar and above
3. MPG set too low Set MPG pressure higher
ON injection
command
( when green
button is
pressed) 4. Auto head valves
NOT reached open
inject position and thus
not providing start signal
to machine Check both Resin and catalyst head
valve have moved to open position.
Observe Metal pin at pneumatic
actuator has moved out.. Approx 8

catalyst valve. If not then increase
shop air pressure or service the
valve at fault.
5. PDC Counter not
reset correctly or set at
zero Press reset firmly or set at least a

is NOT leaking small air volume
from brass body end cap
If this valve has an air leak then it
has triggered the machine to stop.
Investigate why the valve has

Inspect NRV8 for signs of blockage
