3.5 Overtemperature Control
The furnace may be fitted with a “chamber overtemperature control”, if this has been ordered. The
chamber overtemperature control stops further heating if an overtemperature condition is reached,
and heating is not resumed until the system is manually reset. Operating instructions for the
overtemperature controller are referred to in section 3.1 and detailed in the separate controller
manual.
All cupellation furnaces also have an “element overtemperature control” which serves to cut power
temporarily to the heating elements if the temperature in the immediate vicinity of the elements is
too high. Heating resumes when the temperature drops, and manual resetting is not required. This
is controlled by a Eurotherm 2132 (or similar).
2132 Element Controller
The model 2132 overtemperature controller is
made by Eurotherm, and is fitted by Carbolite
configured for immediate use.
The 2132 features easy setting of
overtemperature setpoint, and reading of current
temperature at the overtemperature sensor;
Operation
Use Down and Up to alter the overtemperature setpoint.
Set the element overtemperature controller to approximately 100°C above the maximum or
setpoint temperature. The element overtemperature controller does not trip the furnace when
activated, and when once correctly set may be ignored.
Press Scroll to view the present temperature as seen by the overtemperature controller. Press it
twice, because the first press shows the temperature units (°C).
