Warning Description

The "CC as Enable" function is enabled and there is no power being provided to the CC terminal. 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.

Attempt to Correct

Always maintain safe working conditions by using appropriate personal protective equipment (PPE) where necessary.
Verify if power to the CC terminal was intentionally removed. Resolve conditions that caused the power to be removed. For example, if the CCR is interlocked with a CSS door switch, close the CSS door.
If CC as Enable was unintentionally enabled, navigate to: Configuration Menu > CCR Config > Parallel Inputs > CC as Enable > [Disable].
