HI-LIMIT Instrument
The oven is equipped with a HI-LIMIT instrument. The purpose of the HI-LIMIT
instrument is to provide a protective measure for the product and/or the oven itself. If
the setting on the HI-LIMIT is exceeded, the heating process will discontinue, thus
protecting the product and/or the oven.
Set the HI-LIMIT instrument to a temperature 10°C - 14°C higher than the CONTROL
instrument setpoint or a temperature that should not be exceeded in the process. If the
setting on the HI-LIMIT instrument is exceeded the heater will shut down. The HI-LIMIT
instrument must be manually reset by pushing the RESET button on the HI-LIMIT
instrument.
