Possible cause and actionProblem
•
One or some of the minor modules use too much current. Minor
modules include all modules except the Fraction collector, the
UV monitor and the pumps.
The current is cut off by a temperature sensitive component. The
instrument can be restarted when the temperature has de-
creased. If persistent, generate a System error report and contact
Service.
One or more modules are
automatically turned off
•
The network cable is not connected
Connect the cable, see UNICORN Administration and Technical
Manual.
The instrument cannot be
seen in UNICORN
•
The cable between a module and the ICU is not connected.
Remove valves and check that cables are connected.
•
One or more jumpers are loose or missing.
Check the connections on the back of the instrument. Empty
positions for UniNet-9 connectors 1 to 8 must have connected
jumpers. See the illustration below. The connector 9 should be
protected with a plastic lid and must never have a jumper con-
nected to it.
One or more module(s) is
not found by the instrument
