Installation | Chapter 4 Figure 4 Preventing Chimney Effect Atmosphere Inlet All Moldatherm box furnaces have a factory-installed air/atmosphere inlet. Most inert atmospheres (i.e. nitrogen, argon, and helium) can be safely run in this box furnace. However, maximum temperatures may be derated depending on atmosphere. An initial burn-in period in air is recommended.
| Installation Chapter 4 4. Align the mounting holes in the rear housing panel with the holes in the atmosphere inlet port and secure the assembly with the mounting screws. Figure 5 Atmosphere Inlet Port Hearth Plate Information CAUTION : Most hearth plate materials are made of ceramic fiber and can be broken if dropped.
Start-Up WARNING : After transport and decommissioning, or storage under humid conditions a drying-out process must be performed due to hydroscopic nature of the ceramic fiber insulation. During the drying-out process the equipment cannot be assumed to meet all the safety requirements of the IEC 61010-2-010 standard. WARNING : Observe the following precautions when operating the furnace: Never stand in front of an open furnace.
| Start-Up Chapter 5 12. Highly recommended to Auto Tune unit for application prior to use refer to section “Auto Tuning” . Refer to section “Eurotherm 3216 Controller” for detailed start up steps. Door Seal Check It is very important to check the door seal before using this furnace. Door seal integrity is essential to maintain temperature uniformity and to prevent fumes being released into the area surrounding the furnace.
Page 26
Start-Up | Chapter 5 4. After each adjustment recheck the door seal. The door seal has been adjusted properly if there is no heat loss when operating the furnace up to 500°C. WARNING : When installing, maintaining, or removing the fiberglass insulation, the following precautions will minimize airborne dust and fiber: Keep personnel not involved in the installation out of the area.
Main Controller: 1x8 & 5x16 Segment Programmable | Chapter 6 Main Controller: 1x8 & 5x16 Segment Programmable Eurotherm 3216 Controller The Eurotherm 3216c and 3216p temperature controllers sense the furnace's chamber air temperature (the PV or process value) and provides the heat needed to reach the required set point.

| Main Controller: 1x8 & 5x16 Segment Programmable Chapter 6 The 8-segment programmable 3216c controller consists of microprocessor based three-mode PID (Proportional, Integral and Derivative) and appropriate output switching devices to control the furnace. The programmable controller can be used as a single set point controller or as a programmable controller.
| Main Controller: 1x8 & 5x16 Segment Programmable Chapter 6 Soft Start Power Limit The soft start function limits the power delivered to the heater until it has warmed up. The SS.PWR is the power limit applied until the PV reaches the SS.SP or the timer has elapsed.
Page 44
Main Controller: 1x8 & 5x16 Segment Programmable | Chapter 6 Timer Start Threshold A single threshold value is available to provide a holdback on the entry to the dwell part of the ramp/dwell pair. It holds back the dwell until the PV has reached the band defined by +/- threshold around the PV.
Page 45
| Main Controller: 1x8 & 5x16 Segment Programmable Chapter 6 End Type parameter The action which occurs at the end of program or in reset depends on the configuration of the ‘END.T’ parameter. The ‘END.T’ can be: OFF : The heating is turned OFF, dwEll : Controls at last program setpoint, SP2 : Controls at setpoint 2 (When the timer completes the target setpoint will switch to setpoint 2.
