This procedure sets the Over Temperature Limit heating cutoff to approximately 5 ˚C above the
current chamber temperature. Perform the steps below once the oven has run with no temperature
fluctuations at your application temperature set point for at least 30 minutes .
If the OTL sporadically activates after setting the control, turn the dial very slightly to the right
(clockwise).
The Over Temperature Limit System activates when the oven chamber air temperature exceeds
the setting of the OTL System. If the oven microprocessor controller has failed, or the OTL is set
below your chosen temperature set point, the OTL alarm indicator will turn on and off indefinitely as
the OTL depowers the heating elements each time the temperature exceeds the cutoff limit. If this
is happening, repeat steps 1 - 3 to verify that the OTL is set above the temperature set point.
Contact technical support or your distributor if the OTL continues to activate.
End of procedure
1
If you have not done so already, turn the
Set Over
Temperature Limit
control dial clockwise to the maximum
position.
2
Turn the Over Temperature Limit control dial counterclockwise
until the red Over Temp Limit Activated light illuminates.
3
Slowly turn the dial clockwise until the Over Temperature Limit
Activated light turns off. Stop turning the control.
4
Optional : You may turn the dial slightly to the left to bracket in
closer to the set point temperature. This sets the OT Limit
nearer to the current chamber temperature.
5
Leave the OTL dial set slightly above the activation point.
•
The Over Temperature Limit is now set approximately
5˚C above the current chamber temperature.
