6.0 Operation
Explosive Materials
The furnace must not be used to heat materials which could explode, or
which could emit gases that could form explosive mixtures. If the safe
heating of a material is dependent on its temperature, only heat these
type of materials if the furnace has the optional over-temperature
protection device fitted. Ensure that the over-temperature device is
calibrated and set to an over-temperature safety limit that is sufficiently
large as to avoid any hazards. If in doubt, seek expert advice before
proceeding. Customers are responsible for carrying out their own risk
assessments on the heating of materials.
Do not operate without a work tube
. The furnace must not be
operated without the correctly sized work tube and correspond work
tube adaptor. Otherwise, an operator can access electrically live
element coils that could cause serious injury of death.
Switch off the furnace before loading and unloading.
The furnace
elements must be switched off using the heater switch, item 2 in
"Warning Labels", when the furnace is being loaded or unloaded. The
work tube can become electrically conductive at high temperatures. If
an element has failed and collapsed onto the work tube, the work tube
will become live causing serious injury or death.

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.
For A & B, the control zones are linked so that they all follow the centre zone controller
in a master-slave approach
Note:
l
Option A is
NOT
applicable when using the CC-T1 controller
l
Option B is
NOT
applicable when using the Eurotherm 2132 End Zone Controller
