Warning Description

The CCR was set up to monitor a 24VDC backup power supply. This warning occurs when the monitor is enabled and the 24VDC backup is missing. If no 24VDC backup power supply is installed, this warning will only be seen if the monitor is enabled in the Configuration Menu.

Attempt to correct

• Verify the backup power supply is operational using a DMM.
• If no backup supply is connected: the option for monitoring was unintentionally enabled. To disable, navigate to: Configuration Menu > Monitor Config > Comms 24V Monitor > [Disable]
