This is a typical System Alarm and Warning page.

The n/a indicates there is not an alarm or warning

to display on that line. As depicted, this display indi-

cates a Fuel Pressure alarm for low pressure. This

would be a common alarm for a system that has the

gas line turned off. The “Al” indicates it is an alarm.

The “*” indicates the alarm has not been acknowl-

edged. The “DI2/FUEL PRESS” message indicates it

is a fuel pressure alarm (DI2 was included in the text

by the user to indicate it is Digital Input #2). The “Lo”

indicates the alarm was tripped because the input

value fell below a set threshold.

The message format symbols are explained below:

First 2 characters:

Wr – Warning

Al – Non-shutdown alarm

SD – Shutdown alarm

Third Character:

* – Has not been acknowledged

Last 2 Characters:

Sn – Sensor failure

Hi – Tripped by being greater than threshold

Lo – Tripped by being less than threshold

(blank) – Internal alarm or warning

Press the “ENTER” button while the cursor is on

"ACK" to acknowledge the alarm.

The “*” is now gone since the alarm has been

acknowledged.

Turn the gas line on.

The alarm has cleared since the gas pressure is now

adequate.

Move the cursor to the  on the bottom line by press-

ing the  button twice or the  button once.

Press the “ENTER” button to see the next page.
