Warning Description


This warning may occur on CCRs with multiple communications and channels configured. If Channel A and Channel B are sending different commands to the same CCR, the CCR will go to a failsafe setting. 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.
Ensure the command system is sending only one command to the CCR.
Operate the CCR in Local mode.
