A new feature is the
Process Safety
function. This function provides further protection
for the operators and application. A classic over-temperature device unit would trip and
cause a shutdown if over-temperature cut-off temperature was reached. This could
occur under circumstances where more heat was being generated by a process
(exothermic) than the unit could remove. Switching the temperature control unit off
would remove the only possible method of cooling the application down. Consequently,
the temperature would be able to further increase, creating a risk of injury to personnel
or damage to the application, for example by over-heating a liquid into pressurised
vapour.
Using the
Process Safety
function, the controller recognises when the over-temperature
cut-off is reached, and switches the cooling on. The compressor automatic is
automatically set to
always on
. Even if the temperature continues to rise, the
refrigeration machine will increase its cooling to maximum to minimise the heating.

Danger!
Emergency Procedure: Disconnect Electrical Power!
Turn the Mains isolator (36) to “0”!
Dangerous liquid / vapours from temperature control unit or connected hoses (very hot,
very cold, dangerous chemicals) and / or fire / explosion / implosion:
Evacuate the area, following local regulations and procedures to prevent injury or loss
of life! Refer to the MSDS Safety information for the thermal fluid concerned!
