OPERATION
Timed Heating Profile
The oven is provided with a Timer subsystem that, when set, runs the oven in a steady-state
heating profile at the current temperature set point from 1 minute up to 99 hours, 59 minutes. Allow
the oven to heat to temperature prior to launching a profile. Launching a profile with the
temperature set point set to 150°C immediately after turning on the oven will result in the first
several minutes of the profile spent with the chamber rising from room temperature to 150°C.
When the Timer system is on,
the oven will not heat
unless a profile of 1 minute or greater has
been launched.
The Over Temperature Limit System (OTL)
When set, the mechanical OTL heating cutoff system prevents runaway heating in the oven
chamber. The OTL operates independently of the microprocessor and is provided with a separate,
hydrostatic temperature sensor probe located in the oven chamber. In the event the chamber air
temperature exceeds the current OTL setting, the OTL routes power away from the heating
elements. The OTL will continue to prevent heating until the temperature drops below its limit
setting. The Over Temperature Limit is set by the end-user , typically at approximately 5°C above
the application temperature set point.
