Fault
symptom

Possible cause

Remedies

Machine fails to
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 open to open
position. Observe Metal pin at
pneumatic actuator has moved out..
Approx 8 mm for Resin valve and 5
mm for 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
count of 5

6. Catalyst over
pressure valve operated
- Either the NRV4 has a
blockage OR the
catalyst head valves

(cont’d)

have not opened

fully

Check Catalyst Over pressure valve
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
triggered as it indicates the catalyst
has found significant blockage.
Inspect NRV4 for signs of blockage
