3 120 OCC: To high
pressure
Deviation At some stage in the process of
measure cells the pressure is to
high, this indicates some kind of
blockage in the system.
Run prime and self test from the touch
screen. If this does not help you need
to manually check the hoses and
valves to find the blockage. If it still
does not work - call for service
engineer.

3 122 OCC: Time out
due to Alcom
communication
problem
Deviation Somewhere in the measure
process an Alcom message was
lost and the process could not
continue.
Run prime and self test from the touch
screen. If this does not help
disconnect/connect the power to the
OCC.

3 123 OCC: To low
temperature
Deviation The temperature in the cabinet is
close to zero or below. The liquids
can freeze and the system can be
harmed.
If possible run a shutdown from the
touch screen and don't use the OCC
until it is warmer again. You can
disable the OCC in the management
software.

3 124 OCC: Liquid
leakage in cabinet
Deviation There is some liquid in the bottom
of the cabinet
Try to see were the leakage is. When
the problem is fixed, unscrew the cup
under the cabinet. Empty the liquid and
clean all parts. Run a prime and self
test from the touch screen.

Deviation The waist container is full Replace the waist container and press
the "Waste is empty" button on the
touch screen. Run a self test.
3 126 OCC: Pressure
sensor broken or
leakage/stop in
some hose.
Deviation The pressure sensor seems not
working.
Run prime and self test from the touch
screen. If it still does not work - call for
service engineer. Press the Milk valve
manually to release any pressure in the
system. Read the pressure from the
touch screen (should be around 1 to
1.2 bar). Make sure all valves are
closed. Move the syringe pump a small
distance and read the pressure again.
Is there any pressure difference? If not
try to disconnect/connect power to the
OCC. If it still does not work, replace
the pressure sensor.

hose or valve
failure
Deviation The OCC can't detect any reagent. Is there any reagent left in the bottle?
Try prime and self test. If this does not
help, check hoses and valves manually.
