Oven Temperature is Greater Than T-Rating
Symptom
: The temperature board has been shut down. If the trouble is in Micro #1 then all LED’s
are Off on the Temperature Control board and the zone temperature is greater than the T-Rating. If
trouble is in Micro #2, then the top LED is ON and the actual temperature is greater than the T-
Rating.

Control Mode Screen *Temp Bd Alarm* (flashing)
Alarm Screen Temperature Board:
*Zone Specific
*** TEMP ZONE (#) Alarm ***
*Overtemp
*High Temp
Cause
: The T-rating defines the maximum surface temperature allowed to prevent the ignition of the
flammable liquids and gases. The over-temperature limit prevents the temperatures from reaching
the T-rating limit. The over-temp must be less than the T-rating limit to prevent the temperature from
reaching the T-rating ignition temperature.
Remedy
: Reconfigure T-Rating or upper limit to correct setting. To modify the temperature
configuration table, refer to "DIGITAL TEMPERATURE CONTROLLER" in Section 4. Perform Test
Procedure 30 (Checking Temperature Table Values).
