The incubator must be operating at your incubation application temperature, and must be stable for
at least 1 hour prior to setting the OTL. Perform the following steps to set up the
Over
Temperature Limit heating cutoff system for use:
If the OTL is sporadically activating, you may turn the dial very slightly to the right (clockwise).
If the OTL continues activating, check for ambient sources of heat or cold that may be adversely
impacting the unit temperature stability. Check if any powered accessories in the workspace
chamber are generating heat. If you can find no sources of external or internal temperature
fluctuations, contact Tech Support or your distributor for assistance.
End of Procedure
Set OTL
Example
1. Turn the Set Over Temperature Limit control dial clockwise to the
maximum position, if it is not already set to maximum.
2. Turn the dial counterclockwise until the red Over Temperature Limit
Activated light illuminates.
3. Slowly turn the dial clockwise until the Over Temperature Limit
Activated light turns off. Stop turning the control.
a. The Over Temperature Limit is now set approximately 1
˚C above
the current incubator air temperature.
4. Optional : You may turn the dial slightly to the left to bracket in closer to
the set point temperature. This sets the OTL cutoff threshold nearer to
the current incubator air temperature.
5. Leave the OTL dial set just above the activation point.
