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.
