Appendix D - ADM Event and Error Codes Overview
72 313875J
D2A1
Setpoint Not
Reached
The set point was not reached Deviation
Pump cannot reach the
requested pressure
Increase restriction in the system
Pump cannot reach the
requested flow
Decrease restriction in the system
D3A1
Setpoint
Exceeded
The set point was exceeded Deviation
System underwent a
change that caused a
large drop in restriction
(such as new orifices)
Erase learned System Data, found in the setup
screens under calibration
No material in pumps
Make sure the material lines are open and have
proper feed pressure
D5A1
Invalid Learn
Mode Data
This calibration lets the MCM
know where the ends of the
pump are. If the data gathered
during this process is outside
of normal parameters the
machine will operate with a
greatly reduced stroke.
Deviation
Recalibrate the machine Rerun the learn mode calibration
Loose/bad connection
Check to ensure the pressure transducer is properly
installed and all wires are properly connected
Bad linear position
sensor Verify pump moves to limits, if problem persists
replace linear position sensor
D6A1
Position
Sensor Fault
The linear position sensor is
returning data that should not
be possible during normal
operation
Alarm
Loose/bad connection to
linear position sensor Check to ensure the linear position sensor is properly
installed and all wires are properly connected
Bad linear position
sensor
Replace linear position sensor
Linear position sensor
may be loose where
attached to pump
housing
Re-tighten the sensor and re-calibrate the machine
DDA1
Red Pump
Cavitation
Cavitation was detected on the
given pump
Deviation
Insufficient material
being supplied or
insufficient material
pressure on feed system
Verify that incoming ball valves are open
DDB2
Blue Pump
Cavitation
Deviation Verify that feed pumps are supplying material
Debris or packout in the
incoming fluid filter Inspect filter for debris of filler packout and clean or
replace as necessary
DFA1
Pump Not
Parked The pump failed to reach the
park position
Deviation
Orifices blocked Clear blockage
Hose blocked Clear 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
DSC0
Pumps Not
Defined
The type or size of the Red or
Blue material pumps have not
been defined
Alarm
Properly setup the
system
On the ADM go into the setup screens -> System->
then make sure that the pump type and size are set
(not --)
F7D1
Pump Failed
to Stall
When the pump tried to stall to
pressure the pump traveled
more than it should in normal
operation (only applies to
dead-headed system)
Deviation
Failure of the dispense
valve Ensure the valve has a proper air supply and seals
properly. If not, service the valve as necessary.
Material leak
Visually inspect the machine and hoses for sign of
leakage.
NOTE: This error will display after 2 full
piston strokes so the leak will be substantial.
Out of material Fill tanks
L111
Red Low
Material Level
Low material level in tanks
Deviation Tanks low on material Fill tanks with material
L122
Blue Low
Material Level
Deviation Loose/broken connection
If the tanks appear to have plenty of material check to
make sure the level sensor is connected to the proper
port and that the cord is not damaged
Bad level sensor Replace level sensor
L311
Red High
Material Level
High material level in tanks
Deviation
Defective fill valve
If the tanks appear to have plenty of material check to
make sure the level sensor is connected to the proper
port and that the cord is not damaged
L322
Blue High
Material Level
Deviation
L6A1
Red Auto
Refill Timeout The tank stand has been filing
for a time greater than
expected
Deviation
No material is actually
being fed
Make sure the feed pumps are operating properly
L6B2
Blue Auto
Refill Timeout
Deviation
Loose level sensor
connection
Check for loose or disconnected wires or plugs
Bad level sensor Replace level sensor
