5. Catalyst head valve
has not fully opened
when commanded by
injection command Check both the resin auto valve and
the catalyst auto valve have opened
.The Resin valve must fully open to
signal the catalyst valve to open.
Both should indicate their
respective open positions by the
Resin valve brass pin raised above
the red valve top by at least 7 mm.
The catalyst auto valve should
show the movement open by the
aluminium pin raised by at least 5
mm from the closed position.
Service the valve which is showing
signs of not fully opening.
6. Resin head valve
blocked .This condition
can happen if the
machine has been left
with resin in the system
for extended times
without use.
Internally clean and if necessary
renew internal parts.
Caution NOTE. Always replace the
resin valve locking M5 screws
securely after servicing the Resin
auto valve.
Catalyst flow
appears erratic 1. Air in catalyst feed
pipe or Fluid section Re purge catalyst system. I
Contaminated catalyst also causes
bubbles in system. To remedy
empty entire catalyst system
including catalyst bottle . Wash out
with clean water. Refill with fresh
Catalyst
3. Catalyst Gassing -Clean catalyst system of
contamination.
- Use AAP catalyst system as
MEKP has a greater tendency to
produce gas bubbles more readily
than the more stable AAP systems
Resin flow has
bubbles or
appears erratic
1. Air leaks in the resin
feed intake system.
1.Check all joints for leaks in intake
pipe work and fittings on the resin
pickup fluid section
2. Resin filter blocked Clean resin intake filter
3. Resin Filler loading
too high Lower viscosity of resin OR lower
pump speed until even flow on up
and down pump strokes is observed
Flush does not
clean efficiently
or appears 1.Low air supply
pressure Ensure supply pressure between 6
to 8 bar
