Page 6: Installation
2.0 Installation Unpacking and Handling When unpacking and handling the product, always lift it by its base. Do not use the door or any other projecting cover or component to support the equipment when moving it. Use two or more people to carry the product where possible. Carefully remove any packing material from inside and around the product before use. -
Page 7: Electrical Connections
Ensure that the product is placed in such a way that it can be quickly switched off or disconnected from the electrical supply. Each chamber is fitted with an air guide (a horizontal plate dividing the top from the bottom), and a sample tray (in the lower part of the chamber). Ensure that these items are present. -
Page 8: Gas Supply
The supply should be fused at the next size equal to, or higher than the current on the label. This manual contains a table of the most common fuse ratings. When the mains cable is factory fitted, internal fuses are also fitted. It is essential that the operator ensures that the product is correctly fused. -
Page 9: Desiccator (If Supplied)
The flowmeter on the right is only used to test for leaks in the MFS/1 gas flow. The gas exiting the chamber passes through the valve positioned at the back of the product labelled “OFF/ TEST”. The normal operating position for this valve is “OFF”. With the valve in this position the outlet gas passes directly from the chamber to the gas outlet connection. -
Page 10: 2132 Controller
3.0 2132 Controller Description The 2132 Controller is made by Eurotherm, and is fitted and configured by Carbolite Gero for immediate use. It is a digital instrument with PID control algorithms. The 2132 Controller features: Easy use as a simple temperature controller, where on setting the required tem- perature the controller immediately attempts to reach and maintain it. -

Page 12: Stopping And Starting Control
3.2.5 Stopping and Starting Control It is possible to stop and start the controller without altering the setpoint. Press scroll until the legend 'm-A' (manual/ auto) appears. In this controller, manual means OFF and auto means ON. Press down or up once to show the current on/ off state: 'mAn' for OFF and 'Auto' for ON. -

There are 5 timer modes, but 2 of them are affected by whether the setpoint ramp rate feature is being used, making 7 entries in the table. - Page 14 Timer Mode Description Timer Light The timer starts timing when the actual temperature is within 1 °C On while temperature is mode 1 of the setpoint. At the end of the reaching setpoint. On during timing period, control switches Timed dwell and the timing period.

Page 15: Setting The Timer Mode
3.3.1 Setting the Timer Mode Scroll to 'tm.OP'; use to view and alter the mode. The mode shows as 'OPt.1' to 'OPt.5'. It is not possible to alter the mode while the timer is operating; if the mode cannot be altered, scroll to the 'StAt' parameter and set its value to OFF. -

though it has reached the end of the time period. 3.3.5 End of Time Period Modes 1 and 3: heating stops at the end of timing; the 'm-A' parameter changes to 'mAn'. Modes 2 and 4: heating continues at the end of timing; the 'm-A' parameter remains at 'Auto'. - Page 18 Depending on the furnace or oven model the power limit parameter OP.Hi (Output High) may be accessible or hidden. For silicon carbide heated furnaces the parameter is accessible to allow for compensation for element ageing. In wire-heated chamber or tube furnaces, reducing the power limit is a convenient method of improving control at low temperatures, as outlined below.
- Page 19 User Calibration The controller is calibrated for life at manufacture against known reference sources, but there may be sensor errors or other system errors. User calibration allows compensation for such errors and this controller allows for a user 2-point calibration. This setting is password protected to avoid accidental alteration.
