POWER UP Startup Display
When power is applied to the probe, the cell heater turns on. It takes
approximately one half hour for the cell to heat to operating temperature. This
condition is indicated by a "warm up" display on the LOI (Figure 6-1). This
message will continue to display until the cell is up to operating temperature.
Operating Display
The normal operating display is the % O
2
concentration. The "normal" display
is shown in Figure 6-2.
Error
If there is an error condition at startup, an alarm message will be displayed.
Refer to Section 8: Troubleshooting, to determine the cause of the error. Clear
the error, cycle power, and the % O
2
display should return.
LOI
The Local Operator Interface can be used to change the software and alarm
settings, to adjust the high and low gas settings, and to initiate the calibration
sequence. Refer to the LOI menu (Figure 6-4).
