Reacting to Lockouts
on the Current User Interface
The system responds to three kinds of trouble indica-
tions:
• 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 lock-
out.
• 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. A brief explanation of the
cause of the Hold will appear in a line across the bottom
of the screen.
If a serious problem continues, the system will declare a
Lockout. A brief explanation of the cause of the Lockout
will appear in a line across the bottom of the screen.
Correct this by pressing the OK button. You can also
press the Reset button on the SOLA controller. See Fig.
D6-1.
If an Alert occurs while the system is running, the system
will present a note in a line across the bottom of the
screen.
Each error message includes a number. For a more
detailed description of each message, see the Appendix
at the end of this manual.
