Appendix D - ADM Event and Error Codes Overview
74
313873J
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
R4D0-A
High Ratio
The Ratio of Materials
dispensed is high, exceeding
tolerances entered; Too much
Blue material with respect to
Red.
Alarm
Red Tank Empty, or out
of Red material.
Blockage or Red material
feed. Blockage of Red
Material in Flow Meter, or
elsewhere.
Fill Red material tank or drum.
Check for blockages in Red material flow.
R3D0-D
Deviation
R1D0-A
Low Ratio
The Ratio of materials
dispensed is low, exceeding
tolerances entered; not
enough Blue material with
respect to Red.
Alarm
Blue Tank Empty, or out
of blue material.
Blockage or Blue
material feed. Blockage
of Blue material in Flow
Meter, or elsewhere.
Fill Blue material tank or drum.
Check for blockages in blue material flow.
