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 burners 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 while the system is starting up, the system will declare a Hold or
Lockout:
If a problem occurs while the system is running, a Bell symbol will appear in the upper
left corner of the screen, and the system will present a note across the bottom of the
screen. If you tap the bar which includes the message, the system will present more
information about the problem. Press the OK button to indicate that you have seen the
Lockout or Alert.
If an audible alarm on the display is active, tap the Bell symbol to stop it.
Each error message includes a number. For a more detailed description of each message,
see the “Installation and Operation Manual.”
