Error Messages
Emergency Stop (E-Stop) error message
Agilent AOI systems have four pushbutton stops and one
interlock E-Stop connected to the front access door of the
machine. If any one of these five hardware devices is not
making contact an E-Stop condition will occur.
• If all E-Stop hardware is intact and functioning, request
Troubleshooting the Safety Relay.doc from Agilent Support.
This document discusses what terminals to check for open or
closed circuits and voltage, to pinpoint the exact problem.
• See the Electrical Drawing document for wiring details.
No barcode read in the software
• Verify that the barcode reader is working. Do not stare into
the barcode reader; observe the manufacturer’s warning.
Typically the reader is working if a red laser line is present.
• Verify that the barcode reader is connected to the correct
COM port at the back of the system. If the system was not
purchased to work with a barcode reader, you will need
additional hardware, either Agilent supported or purchased
directly from the manufacturer, to supply power and trigger
to the reader. For more information, contact Agilent Support.
• Check that the correct COM port is set in the registry.
• Verify that the barcode reader was set up with a preamble of
0 and a postamble of CR.
• The communication of the reader barcode can be verified
using the sj5000 software (from the
Tools
menu click the
Barcodes
folder), HyperTerminal or the manufacturer’s
software.
Agilent recommends Microscan barcode readers with ESP
software.
