Sensor Configuration
Select either normal operations or hydrocarbon upset condition operations.
The hydrocarbon upset condition option allows the system to recognize a hydro‑
carbon upset condition and trigger an alarm if that condition is reached.
If you do not want to use the
Hydrocarbon Upset
option, select
Nor-
mal
for the Sensor Configuration.
Configuring the Sensor
1. From the Setup Key menu, select Sensor Config .
2. Select Normal or Hydrocarbon Upset .
If you select Hydrocarbon Upset , Alarm 4 becomes fixed as a high
oxygen alarm and also acts as a hydrocarbon upset alarm. You may
need to reenter your alarm set points and configuration.
3. When you select Hydrocarbon Upset , you are prompted to enter a millivolt
value that, if exceeded, triggers the hydrocarbon upset condition.
If the oxygen reading drops to 0 PPM, and the millivolt value you entered is
reached or exceeded, the system displays a low oxygen/high hydrocarbons
message rather than the oxygen reading (assuming oxygen is displayed on
the control unit). It also trips Alarm 4.
If the oxygen reading is 0, but the cell millivolt threshold value has not been
reached, the system will display a low oxygen/low hydrocarbon message.
Once a hydrocarbon upset condition is reached (and assuming you selected
Hy-
drocarbon Upset
), the display switches from displaying the oxygen reading to
displaying a hydrocarbon condition text message.
