ACKNOWLEDGE (ALARM SILENCE/SEQUENCE TIME) button performs a function; other buttons will show
settings but won’t allow them to be changed). If the front panel controls don’t seem to work, use the AMI
User Interface to change the security settings.
Front Panel Controls:
The controls all work the same way. You press the function you want for a second, and let go, and the
display will show the value corresponding to that function, for about 3 seconds. For example, if you press
the OUTPUT RANGE button for a second, the display will show the full scale output range. You can change
this value (if the security setting allows) by then pressing the UP or DOWN arrow button within about three
seconds. You can either press this once for a small change, or you can hold it down, in which case the
number will change slowly at first, and then faster. If you overshoot your target, press the other button to
go back, and the display will again start moving slowly. If you release any of the buttons, or don’t press the
UP or DOWN buttons for three seconds, the unit will cycle back into normal operation and store the new
value.
Output Ranges
The output range is the range to which the 4-20mA analog output signal and the alarm settings correspond.
Output ranges
0-1%, 0-5%, 0-10%, 0-25%. 0-1000ppm and 0-100% are options.
View Output Range
Press the OUTPUT RANGE button on the front panel for a second, and let go. The display will show the full
scale value of the output range for about three seconds, and then change back to the oxygen reading.
Change Output Range
Press the OUTPUT RANGE button for a second and let go. While the output range value is displayed (you
have approximately three seconds), press the UP or DOWN arrow buttons to change it. The output range
will change to whatever you want. Simply leave it or select another function and the range will be stored
and the system updated. You will note that if this results in an alarm change, the alarms will change as soon
as the unit starts showing the reading again. If the output range does not change, the security level must be
set to full or span only security. In this case change the security level with the laptop and the AMI User
Interface program.
Alarm Set Points
The alarm set points can be viewed and changed (if security allows) from the front panel. All the other
alarm configuration settings can only be changed with the AMI User Interface program.
