Warning Description


Channel B of the communications card is not receiving a signal with the CCR in Remote. If no communications card is installed, this warning will be seen only if the Comms Config is enabled in the Configuration Menu. 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 the communications system and wiring is operational.
If no communications card is installed: the setting for Comms Config was unintentionally enabled.
To disable, navigate to: Configuration Menu > Comms Config > [Disable].
