Pressure
difference between
A and B material
is greater than the
defined value.
Ensure material flow is
equally restricted on both
material lines.
Pressure
imbalance is
defined too low.
Ensure that the pressure
imbalance value, on the
System Setup screen, is at
an acceptable maximum
pressure to prevent
unnecessary alarms and
abort dispenses.
Out of material.
Fill tanks with material
Fluid leaking from
heater inlet rupture
disk.
Check if heater
and PRESSURE
RELIEF/SPRAY valve are
plugged. Clear. Replace
rupture disk. Do not replace
with a pipe plug.

Pressure Imbalance
B High
Feed system
defective.
Check feed pump and
hoses for blockage. Check
that feed pumps have
correct air pressure.
Flow is too high at
current setpoint.
Use a smaller mix chamber
that is rated for the unit
in use. If recirculating,
decrease flow or decrease
temperature setpoint.
Bad RTD or bad
RTD placement
against heater.
Swap A and B heater output
cables and RTD cables and
see if issue follows. If so,
replace RTD.
T2DA
Heater A
Low Temperature A
Bad heater rod or
loose heater wire.
Confirm resistance of
heater. Heater resistance
should be 9-12 Ω for 10
kW systems and 6-8 Ω
for 15 kW systems. If out
of tolerance, check for
loose heater rod wire(s).
Reconnect wires or replace
heater rod if necessary.
