•Bothhigh(highandhigh-high)alarms,or

•One high and one low alarm, or

•Both low (low and low-low) alarms.

2.Are either or both of the alarms to be configured as failsafe?

In failsafe mode, the alarm relay de-energizes in an alarm condition. For non-failsafe operation, the relay is energized in an alarm condition. You can set either or both of the concentration alarms to operate in failsafe or non-failsafe mode.

3.Are either of the alarms to be latching?

In latching mode, once the alarm or alarms trigger, they will remain in the alarm mode even if process conditions revert back to non-alarm conditions. This mode requires an alarm to be recognized before it can be reset. In the non-latching mode, the alarm status will terminate when process conditions revert to non- alarm conditions.

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

3.3.3to 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.

Use the DÑ keys to choose between % or ppm units. Then press Enter to move to the next screen.

Five parameters can be changed on this screen:

•Value of the alarm setpoint, AL1: ####

•Out-of-range direction, HI or LO

•Defeated? Dft:Y/N (Yes/No)

•Failsafe? Fs:Y/N (Yes/No)
