4. Are either of the alarms to be defeated?

The defeat alarm mode is incorporated into the alarm circuit so that

maintenance can be performed under conditions which would normally
activate the alarms.

The defeat function can also be used to reset a latched alarm. (See

procedures, below.)

If you are using password protection, you will need to enter your

password to access the alarm functions. Follow the instructions in Section
4.3.3 to enter your password. Once you have clearance to proceed, enter
the

Alarm

function.

Press the

Alarm

button on the front panel to enter the

Alarm

function. Make sure that AL–1 is blinking.

AL—1

AL—2

Choose Alarm

Set up alarm 1 by moving the blinking over to AL–1 using the < >

arrow keys. Then press

Enter

to move to the next screen.

AL—1 98.00 %

HI

Dft—N Fs—N Ltch—N

Five parameters can be changed on this screen:

Value of the alarm setpoint, AL–1 #### % (oxygen)

Out-of-range direction, HI or LO

• Defeated?

Dft–Y/N (Yes/No)

• Failsafe?

Fs–Y/N (Yes/No)

• Latching?

Ltch–Y/N (Yes/No).

To define the setpoint, use the < > arrow keys to move the blinking

over to AL–1 ####. Then use the

∆∇

arrow keys to change the number.

Holding down the key speeds up the incrementing or decrementing.
(Remember, the setpoint units are percent-of-oxygen.)

To set the other parameters use the < > arrow keys to move the

blinking over to the desired parameter. Then use the

∆∇

arrow keys to

change the parameter.

Once the parameters for alarm 1 have been set, press Alarms again,

and repeat this procedure for alarm 2 (AL–2).
