Page 6: Installation
2.0 Installation 2.0 Installation Unpacking and Handling When unpacking or moving the product always lift it by its base or by both ends of the main body. Never lift it by its work tube or the surrounding insulation. Use two or more people to carry the product and control box. - Page 7 2.0 Installation Ensure that the product is placed in such a way that it can be quickly switched off or disconnected from the electrical supply. If the product is supplied with a work tube or any accessories fit these into position. For optimum temperature uniformity, insulating plugs should be placed in the tube ends as shown in fig.1.

Page 13: Operation
4.0 Operation 4.0 Operation Operating Cycle This product is fitted with an instrument switch which cuts off power to the control circuit. Connect the product to the electrical supply. There is also a heater switch which can be used to disconnect power to the elements. Operate the instrument switch to activate the temperature controller. -
Page 14: 3-Zone Control Methods
4.0 Operation The two images below are typical examples of control panel layouts. 3-Zone Control Methods There are three different control options (A, B & C). (A) Back to back thermocouples (B) Retransmission of Setpoint (C) Independent control The models listed in this manual are designed to achieve an extended uniform temperature zone, through use of three control zones, rather than achieving different temperatures in each zone. -
Page 15: Back-To-Back Thermocouples
4.0 Operation Note: Option A is NOT applicable when using the CC-T1 controller Option B is NOT applicable when using the Eurotherm 2132 End Zone Controller A. Back-to-Back Thermocouples This is the most commonly supplied option. The centre zone of the tube furnace is controlled directly by the centre zone temperature controller. -
Page 16: Independent Control
4.0 Operation It is possible to set an offset (local trim) between the centre and end zone controllers. This can be either a positive or negative difference from the centre zone temperature. Once entered, this offset will always be added to, or subtracted from, the retransmitted setpoint temperature. -
Page 17: Tube Life
4.0 Operation Switch off the heater switch whenever loading or unloading the product. The elements are isolated when the heater switch is OFF. This switch cuts both sides of the circuit via a contactor. Tube Life A ceramic work tube may crack if work pieces are inserted too quickly or at temperatures below 900 °C (when the tube is more brittle). -
Page 18: Power Adjustment
4.0 Operation Power Adjustment The control system incorporates electronic power limiting. The power limit parameter OP.Hi is accessible to the operator and can be used to adjust the furnace to the actual supply voltage. The models covered by this manual are designed for use over the range of voltages 200 V - 250 V (or, if ordered, 100 V - 125 V), and the power limit parameter is set accordingly. -
