MTF 9/15 ONTROLLER PERATION Eurotherm 2132 When switched on, the controller lights up, goes through a short test routine, and then displays the measured temperature and starts to control. The output light glows or flashes as heating occurs. The Page key allows access to parameter lists within the controller;... - Page 6 MTF 9/15 Altering the Ramp Rate SPrr It is possible to limit the rate of heating by setting a ramp rate. Press Scroll until the legend (SetPoint ramp rate) is displayed. Use Down or Up to display and adjust the value. The ramp rate sets the maximum rate of heating or cooling in degrees per minute.
- Page 7 MTF 9/15 Operation With the Timer The 2132 can be used as a process timer allowing timed heating or timed delay, according to the options in the table. 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 11: Repairs & Replacements
MTF 9/15 & R EPAIRS EPLACEMENTS Safety Warning – Disconnection from Supply Always ensure that the furnace is disconnected from the supply before repair work is carried out. Safety Warning - Refractory Fibrous Insulation This furnace contains refractory fibres in its thermal insulation. These materials may be in the form of fibre blanket or felt, vacuum formed board or shapes, mineral wool slab or loose fill fibre. - Page 12 MTF 9/15 Upon reassembly ensure that the element wire is deeply embedded in the grooves in the ends of the insulation and held away from the foil by insulation beads. The foil should be neatly and firmly wrapped so that it positively locates the beads. When refixing the wrapped element position the beads just above edge of the metal channel to maximise the clearance between the outer case and the wires.
