Hazardous Area Oxymitter 4000
d. SYSTEM/Status
1. Alarm s – 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 O2 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 tem perature
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-
ented as desired by the user.
