ET Tracking
Minimum ET Limit
Communications board Electronics Temperature (ET) lowest
operating limit from specification.
Minimum ET
Value
Communications board Electronics Temperature (ET) lowest
measured value
ET Dn Cnt
The total number of minutes that the Communications board
Electronics Temperature (ET) has been below the lower stress limit
(ET Lower Limit)
ET Upper Limit
High Electronics Temperature stress limit
– if the Communications
board ET exceeds this limit, the ET Up Cnt and ET Up Time will be
updated. Value is equal to “Max ET Limit” minus 10% of limits
range.
ET Up Time
Displays time since the Communications board Electronics
Temperature was last measured as exceeding the ET Upper Limit
(in minutes)
ET Lower Limit
Low Electronics Temperature stress limit
– if the Communications
board ET exceeds this limit, the ET Dn Cnt and ET Dn Time will be
updated. Value is equal to “Min ET Limit” plus 10% of limits range.
ET Dn Time
Displays time since the Communications board Electronics
Temperature was last measured below the ET Lower Limit (in
minutes)

Temp Module
Install Date
The Temperature Module Installation Date
Sensor Service Life
Percent of the expected Service Life that the Temperature Module
has been in service. Value is based on electronics temperature.
Service life accumulates faster at higher temperatures with an
exponential relationship.
Sensor Stress Life
Percent of Temperature Sensor service life spent in stressful
conditions. Indicates the % of service life where one or more of
Process Temperature, processor core temperature, or electronics
temperature are within 10% of respective range limits.
Temp Module
Time in Service
Total time that the Temperature Module has been in service. Time
based on the Temperature Module Install Date.
Temp Sensor
Time in Service
Total time that the Temperature Sensor has been in service Based
on the Sensor Install Date
ET Tracking
Maximum ET
Value
Temperature Module Electronics Temperature (ET) highest
measured value
ET Up Cnt
The total number of minutes that the Temperature Module
Electronics Temperature (ET) has exceeded the upper stress limit
Minimum ET
Value
Temperature Module Electronics Temperature (ET) lowest
measured value
ET Dn Cnt
The total number of minutes that the Temperature Module
Electronics Temperature (ET) has been below the lower stress limit
