Appendix D - ADM Event and Error Codes Overview
313875J 73
MBH1 Low Oil Level
The volume of oil in the tank is
below the minimum level
needed for the system to
properly operate
Alarm
Low oil level Check oil level and if low add more hydraulic fluid
Loose/bad connection
Check to ensure the hydraulic oil level sensor is
properly connected to the MCM and that the wire has
not been damaged
Bad level sensor Replace sensor
Leak in hydraulic driver
Inspect hydraulic driver end seals and early leak
detection tubing. Replace seals as necessary and
replace lost oil.
Leak in the hydraulic
reservoir, heat
exchanger Inspect the hydraulic reservoir fittings and filter for
leaks. Repair or replace as necessary and replace
lost oil.
MBN1
Low Motor
Performance
The motor magnetism has
decreased to the point where
performance is greatly reduced
Advisory
Prolonged exposure to
heat or high voltage
If error persists and performance can no longer
satisfy the user requirements the motor will need to
be replaced
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
