Introduction Intended Use The Type 30400 Automatic and Programmable furnaces are general laboratory and heat treat- ing furnaces. For optimum element life, Barnstead Thermolyne recommends these fur- naces for applications requiring temperatures from 400°F (204°C) to 1800°F (982°C) for con- tinuous use, or temperatures from 1800°F (982°C) to 2000°F (1093°C) for intermittent use.
Unpacking Visually check for any physical damage to the shipping container. Inspect the equipment surfaces that are adja- cent to any damaged area. Open the furnace door and remove the packing material from inside the furnace chamber. Vacuum the chamber prior to use to remove the insulation dust due to shipment.
Installation Site Selection Caution Install furnace on a sturdy surface and allow adequate Be sure ambient temperature does not space for ventilation. exceed 40°C (104°F). The recommended ambient temperature is 17°C - 27°C. Ambients above this level may result in Electrical Connections damage to the controller.

Single Setpoint Models w/OTP Temperature single setpoint model w/ OTP furnace controller Output 2 Output 1 Display is a single setpoint controller which provides a single digital display to indicate the current chamber tempera- ture or setpoint temperature. This temperature con- troller features sensor break protection, self-tuning capability and over temperature protection (OTP) with an additional OTP relay device.
/OTP INGLE ETPOINT ODELS W To View or Change the Setpoint To view the setpoint, press and release the UP or DOWN buttons. If you want to change the setpoint, continue press- ing until the desired setpoint value is displayed and then release the button.
/OTP INGLE ETPOINT ODELS W Pid List Pb: Proportional band (in display units). ti: Integral time in seconds. td: Derivative time in seconds. ACCS List Code: Access code (Code needed to enter or change the other configuration parameters which are not normally accessible.) Not accessable.
/OTP INGLE ETPOINT ODELS W Sensor Break Protection This controller provides sensor break protection in the event the thermocouple opens. If an open thermocou- ple condition occurs, the digital display will blink “S.br” and the power to the heating element will be shut OFF (Cycle light will extinguish).
/OTP INGLE ETPOINT ODELS W Tuning This controller incorporates a self-tuning feature which determines the optimum control parameters for the best temperature accuracy with your load and setpoint. Use this feature the first time you use your furnace and each time you change either your setpoint or the type of load you are heating.
Single Ramp & Dwell Note These instructions are used with the Single Setpoint models with OTP only (See models listed on front page). Functions This type of controller has single ramp and dwell program- ming capabilities. The Ramp and Dwell can be configured to five different modes.
& D INGLE WELL ONTROLLER • The Dwell time can be set by changing the “dwEll” variable to the desired value. Dwell time units are in minutes. • The program Status can be set by changing the “StAt” variable to “run” or “oFF.” This variable will start or stop the program.
