Appendix D - ADM Error Codes
78 3A2175A
N4A1
Pump Failed
to Move
The MCM attempted to move
the pump but no movement
was detected
Deviation
Motor failure
Visually check to ensure the pump is moving, if not
ensure the motor is wired properly
Hydraulic power pack
failure
If motor is moving but pump is not and pressure is not
building they hydraulic power pack may need
servicing
Loose/bad connection to
the linear position sensor
Check to ensure the linear position sensor is properly
connected to the MCM and the wiring has not be
damaged
Failure of the linear
position sensor
Replace the linear position sensor
Motor no longer coupled
to hydraulic pump
Reset coupler per specifications and retighten set
screws
Supply tube from
hydraulic pump to
manifold is loose or
broken
Retighten or replace supply tube
Broken motor shaft Replace motor
Over-pressure valve
dumping to tank
Verify that no outside forces are stopping the pump
from moving, then inspect over-pressure valve for
damage or debris
P400
Thermal
Pressure
Rise
Pressure has risen to an
unsafe level due to thermal
expansion of materials. All
conditioning zones have
automatically been turned off.
Deviation High pressure
Open the dispense valve manually or open the valves
to bleed pressure
P4A1
Red Pressure
Shutdown
The material pump pressure
exceeded the maximum
operating pressure as defined
in the setup screens
Alarm
Dispense valve failed to
open
Check to make sure the dispense valve is properly
configured and connected to the MCM
P4B2
Blue
Pressure
Shutdown
Alarm
Bad dispense valve Replace dispense valve
Restriction in the
material lines
Check to ensure there is no blockage
Invalid maximum
pressure defined
Make sure the requested pressure is within the max
operating pressure, which can be found on the setup
screen System 1
Orifices blocked Clear blockage
Hose blocked Clear blockage or replace hose as necessary
Dispense valve failed to
open
Check to make sure the dispense valve is properly
configured and connected to the MCM
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
