P4D0
Pressure
Imbalance
The pressure difference
between the Red and Blue
material is greater than the
defined amount
Alarm
Dispense line is clogged
Ensure the material flow is equally restricted on both
material lines
Pressure imbalance is
defined too low
On the ADM go into the setup screens -> System->
and ensure the pressure imbalance value is the
maximum acceptable to prevent unnecessary alarms
which will abort dispenses
Orifice blocks closed off
too much on one or both
sides Verify that one or both of the orifice blocks dispense
when adjusted to the fully open position then adjust
accordingly
Debris in the orifice block
Relieve system pressure then remove the orifice from
the orifice block and inspect for debris in the cavity
Material fillers may have
packed out in an orifice
Relieve system pressure and remove the orifice from
the orifice block and inspect for pack out. Clean or
replace as necessary.
Out of material Fill tanks with material
Feed system defective Replace defective item
P6A1
Red Pressure
Sensor Fault The pressure sensor is
providing invalid/no pressure
readings
Alarm Loose/bad connection
Check to ensure the pressure transducer is properly
installed and all wires are properly connected
P6B2
Blue
Pressure
Sensor Fault
Alarm
Bad sensor Replace pressure transducer
No material in pump Fill tanks
T1A6
Red Tank
Low Fluid
Temp.
Fluid temperature is below the
defined low alarm limit
Alarm
Tripped circuit breaker Visually check circuit breaker for a tripped condition
T1B5
Blue Tank
Low Fluid
Temp.
Alarm
T1A3
Red Inline
Low Fluid
Temp.
Alarm
T1B1
Blue Inline
Low Fluid
Temp.
Alarm
T1A2
Red Hose
Low Fluid
Temp.
Alarm
T1B4
Blue Hose
Low Fluid
Temp.
Alarm Low power
Measure voltage across input terminals on power line
filter. Voltage should measure between 190 and 264
Vac
T1A7
Red Chiller
Low Fluid
Temp.
Alarm
Cable unplugged/loose
power
Check for loose or disconnected wires or plugs
T1B8
Blue Chiller
Low Fluid
Temp.
Alarm Bad heater(s) Measure resistance of heater(s)
T3H1
Oil Temp.
Cutback
The hydraulic oil temperature
is approaching a level where
damage is possible so the
Motor Control Module is
limiting the output to a safe
level
Deviation
No power to fan Check cord to make sure fan has power
Debris in fan or fan grill Clear debris from fan/fan grill
Low air volume from fan
Try to stop fan by lightly pressing on the center with a
pencil eraser. If the fan slows down easily it will need
to be replaced
T3N1
Motor Temp.
Cutback
Motor temperature is
approaching a level where
damage is possible so the
motor control module is limiting
the output to a safe level
Advisory
No power to fan Check cord to make sure fan has power
Debris in fan or fan grill clear debris from fan/fan grill
Low air volume from fan
Try to stop fan by lightly pressing on the center with a
pencil eraser. If the fan slows down easily it will need
to be replaced
Ambient environmental
conditions are too hot
Move machine to an area below 120°F
Motor/pump coupler may
be rubbing on hydraulic
pump
Reset coupler per specifications and retighten set
screws
