Model 3010

4-14: Part I

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.

AL1 AL2

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.

AL1 10 % HI

DftN FsN LtchN

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, setpoint units are
parts-per-million.)

•

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).

•

To reset a latched alarm, go to

Dft–

and then press either

∆

two

times or

∇

two times. (Toggle it to

and then back to

)
