SMDUE1 Temp 1 Not Used Temperature sensor port #1 on SMDUE1 is not used.
Temperature probe is enabled but not plugged in. … …
SMDUE1 Temp 10 Not Used Temperature sensor port #10 on SMDUE1 is not used.
SMDUE1 Temp 1 Sensor Fail Temperature sensor #1 on SMDUE1 failure. Replace temperature sensor.
Note: The alarm “Temp Sensor Fail” will occur if the
temperature probe fails internally or is not plugged in;
however, this alarm will be suppressed if “Temp Not
Used” alarm is active.
