Warning Description

The CCR has determined an error with the output card on the DCMU. If CSS was installed, contact Airport Lighting Company. If CSS was not installed: the option for CSS functionality was unintentionally enabled. To disable, navigate to: Configuration Menu > CSS Config > [Disable]. When the CCR determines a warning or setpoint alarm, it will engage the indicator light and the warning will be shown on line 1 of the CCR display. The CCR will continue to operate in the event of a warning. Although the CCR will continue operating, warning conditions must still be noted and fixed. Allowing the CCR to operate in a warning state may cause problems for efficiency, general safety, and longevity of equipment.
