Chapter 9: Troubleshooting
6408 - iButton Read Error
Message: "Unable to read system information from iButton
persists, consult the Operation and Maintenance Manual for further instructions."
Explanation: This is a failure to read information from the iButton. This information includes the serial number,
family, and model. Possible reasons for failure include corrosion on iButton contacts, a gap between the iButton
and system board contacts, or a component failure. Consult GE Analytical Instruments for further instructions on
determining the root cause.
6409 - Internal Communications Error
Message: "Internal communications problem. Please power cycle the Analyzer. If the problem persists, consult
the Operation and Maintenance Manual for further instructions."
Explanation: A module in the Analyzer is not communicating over the bus. First, evaluate the LEDs on the
individual boards. You can sometimes view the reflection of the LEDs looking through the hole on the back cover
of the instrument. Or, for a better view, remove the back cover. All boards should have a green LED to indicate
power. Any yellow LEDs blinking faster than once per second, other than on the NDIR board (see figure 55), may
indicate a problem with the board. If this is the case, shut down the Analyzer and turn off power. Check that all
connections on the gray ribbon cable are secured to their respective boards. If the problem persists, export the
errors and contact GE Analytical Instruments for further instructions.
N :
It is not abnormal for the yellow LED on the NDIR board to blink faster. However, on
OTE
Analyzer start-up the rate should be consistent with the other boards' LEDs.
6411 - CO Gas Leak Detected Warning

Message: This warning has been triggered because CO
been present. First, perform a Reactor Liquid Flow test and a Bypass Liquid Flow test. Then, perform the gas leak
tests in diagnostics and ensure system is not leaking. Continue running sample. If the error persists, replace
reactor seals, pinch tubing, and water in GLS."
Explanation: CO was detected by the NDIR when no CO

instructions detailed in the warning message. For details on performing the tests, refer to "Liquid Flow," on
page 194.
6412 – Acid Error
Message: "The acid container needs attention."
Explanation: The level sensor in the acid container indicates that the container should be refilled.
6413 – Oxidizer Error
Message: "The oxidizer container needs attention."
Explanation: The level sensor in the oxidizer container indicates that the container should be refilled.
