WPS Troubleshooting

Accessing the Health Log:

The Health Log contains a list of events, including both normal conditions and error conditions. Each WPC and solar kit maintains a separate log. These can be very useful for troubleshooting. Select “Health Log” in the Polara App main menu. The Name / ID of the currently connected device is visible at the top. To read the Health Log from this device tap “Read”. The current log is downloaded and displayed. Swipe the screen to browse through the log. Tap the menu symbol at the top right to access a list of actions. The menu symbol is shown as three dots. You can choose to clear the log, export the log to an email address, or access diagnostics. For help with a particular issue, or a message of concern, contact Polara Tech Support. You may be asked to provide a health log via email. Note: You must tap the Read button prior to exporting the health log, otherwise the health log export will only include device information and not the entire health log of the unit.

Common Problems and Solutions:

• Whitelist Full:

If the Field Service App displays an error indicating that the WPC’s whitelist is full, the WPC’s whitelist must be cleared prior to trying to associate a Wireless Ped Pole. See section 5 for instructions.

• Lockout:

Repeated entry of an incorrect password during association will cause the WPC to go into lockout mode. This lockout must be cleared before the WPC will accept association requests. To clear the lockout, connect to the WPC from Field Service App and tap the “Info/Diagnostics” button, then tap the “Clear Lockout” button and confirm the lockout is now cleared.

• Constant Call after Replacing Wireless Ped Pole:

The WPC locks in a constant call when it loses communication with a solar kit associated with it. If a solar kit is deliberately moved or replaced, the installer needs to tell the WPC not to look for that solar kit anymore. To do this, navigate to the “Info/Diagnostics” screen and touch the “Reset Ped Calls” button.

• Failure to Complete Firmware Upgrade on Older Android Devices:

Some older Android devices (prior to Android 13) might experience problems reconnecting to the WPC during firmware upgrade. If this occurs:

• Try connecting to the device manually and restarting the firmware upgrade.
• If that doesn’t work, try using a newer Android device or an iOS device instead.

Fail Safety:

The WPC includes fail safety operation that will automatically lock in a call when the following conditions arise:

• Loss of connection to an associated APS lasting longer than 5 seconds.
• Detection of a conflict interval condition on the Ped Head (e.g., walk and don’t-walk both on at the same time).
