Power Supply
Problems
Power supply problems often involve a blown fuse, faulty electronic
component, or even something as simple as a disconnected cable.
Use extreme care when you replace a fuse.
Communication Communication problems described in this section involve the links
between the data system (PC and software) and the Luminex 200
analyzer and XYP instrument. This section does not address
communication issues with other peripheral devices.
The term “Communication” refers to:
• The transfer of data between the PC and the analyzer.
• The current status of the analyzer and XYP instrument.
• Instrument readbacks.
• Instrument control, sample acquisition, session uploading, and
start, stop and pause features.
Symptom Possible problem Solution
Analyzer will not turn on, or
XYP will not turn on.
The power cord is disconnected. Verify that the power cord is
plugged in.
No voltage is coming from the
electrical outlet.
Verify that the electrical outlet is
operational.
The power supply is faulty. Contact Technical Support.
A fuse has burned out. See page 28 for instructions on
changing fuses.
Fuses continue to open (blow). A component has a short circuit. Contact Technical Support.
Symptom Possible problem Solution
PC cannot initialize
communication with analyzer.
The communication cable is
unplugged, or plugged into the
wrong port.
Check the communications
cable connections.
The XYP or the analyzer power
is not turned on.
Turn off the PC and then turn on
the analyzer, XYP, and then the
