ABOUT LOCKOUTS, HOLDS, AND ALERTS
The system responds to three kinds of trouble indications:
• A”lockout” is caused by a serious problem that might involve a safety issue. Once
the controller enters a lockout, the burner will shut down, and will not be allowed
to run again until the cause of the problem is corrected, and you reset the control
system.
• The system may enter a “hold” for a period of time before locking out. This allows
the controller to see if the error becomes resolved prior to the hard lockout.
• An “alert” indicates that some feature of the control system’s operation was not
correct, delayed, or waiting for a response. This does not necessarily indicate a
problem.
If a problem occurs, the system will present a note across the bottom of the screen:
Example - Lockout or Hold Indication
Correct the problem, then press the round OK button to reset the control.
Each error message includes a number. For a more detailed description of each message,
see the “Installation and Operation Manual.”
