General Troubleshooting Guidelines

4–2
This section will help you narrow down the source of any problem you may
encounter. Please read the following troubleshooting steps:
1. Check for a Warning or Fault message on the Conext System Control Panel
or a Fault code on the inverter information panel. If a message is displayed,
record it immediately.
2. As soon as possible, create a detailed record of the conditions at the time the
problem occurred.
following:
• Loads the Conext XW+ was running or attempting to run.
• Battery condition at the time of failure (for example battery voltage or
temperature) if known.
• Recent sequence of events (for example, charging had just finished,
utility grid had failed but the inverter did not start up).
• Any known unusual AC input factors such as low voltage or unstable
generator output.
• Extreme conditions which may have existed at the time (for example,
temperature or moisture).
3. Attempt the solution corresponding to the Warning or Fault message in
Table 4-3 on page 4–12 or Table 4-6 on page 4–19.
4. If your inverter information panel or Conext SCP is not displaying a Fault light,
check the following list to make sure that the present state of the installation
allows proper operation of the unit. See also "Inverter Troubleshooting" on
page 4–4 and "Battery Charger Troubleshooting" on page 4–7.
• Is the Conext XW+ located in a clean, dry, adequately ventilated area?
• Have the AC input breakers opened? If so, your passthrough load may
have exceeded the rating of one or more of the input breakers.
• Are the battery cables adequately sized and short enough? See the
Conext XW+ Installation Guide for more information.
• Is the battery in good condition and are all DC connections tight?
• Are the AC input and output connections and wiring in good condition?
• Are the configuration settings correct for your particular installation?
• Are the display panel and the communications cable properly connected
and undamaged?
• Are the battery temperature sensor and its cable properly connected
and undamaged?
5. Contact Customer Service for further assistance. Please be prepared to
describe details of your system installation and provide the model and serial
number of the unit. See page ii for contact information.
