d. SYSTEM/Status
1. Alarms – Diagnostic alarms. See
Section 8, TROUBLESHOOTING.
2. PID Parameter – Displays the line volt-
age, powering the Oxymitter, and infers
the temperature control algorithm being
used to control heater temperature.
3. Reset Device – Device can be reset
here as opposed to re-powering. Cali-
bration parameters will be lost.
e. SYSTEM/Software
This is data regarding the Oxymitter 4000
software version, and errors that may have
occurred.
f. SENSOR DATA
Displays information about the O
2
cell and
thermocouple.
1. Temperatures
(a) O2 Temp – Indicates the thermo-
couple temperature at the sensing
cell; this should always be 736°C.
(b) O2 Temp Max. – Maximum tem-
perature the cell has seen. (Some
process temperatures can exceed
the 736°C setpoint temperature,
and this will indicate this condition.)
(c) Board Temp – The temperature
inside the Oxymitter electronics
housing (85°C is the max.).
(d) Board Temp Max. – This is the
maximum temperature that the
electronics has experienced over
time.
6-7 LOI INSTALLATION
The LOI connects to the top of the electronic
assembly in the electronics housing. There are
four matching connectors on the back of the LOI
module, Figure 6-5, that allow the LOI to be ori-
