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 control panel to enter the

Alarm

func-

tion. 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 1.00 % 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

Δ∇ 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

Δ∇ 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).

To reset a latched alarm, go to Dft– and then press either

Δ two

times or

∇ two times. (Toggle it to Y and then back to N.)

–OR –

Go to Ltch– and then press either

Δ two times or ∇ two times.

(Toggle it to N and back to Y.)
