12.3 Over/under temperature safety device class 2 (option)
The over-/under temperature safety device consists of two entry mod-
ules (9a) and (9b) located in the lateral control panel. Both modules can
be set from -50 °C / -58 °F (MKF) or -80 °C / -112 °F (MKFT) up to 200
°C / 392 °F and serve to define the maximum high and low temperature
limits.
With this option, the safety controller (chap. 12.2) must be
set to maximum temperature.
(9a) Upper module: Entry of higher limit temperature.
(9b) Lower module: Entry of lower limit temperature.
When the temperature inside the chamber leaves this tolerance band-
width, the temperature control, and herewith the heating and refrigera-
tion, are turned off permanently.
At the corresponding entry module, the red pilot lamp K1 lights up (K2 is
without function).
The controller displays the alarm message „TEMP LIMIT“ (chap. 13).
Additionally there is an audible alert, provided that the buzzer has not
been deactivated in menu “User level”. In the graphical representation,
the blue line “CLASS” is displayed enlarged (chap. 7).
Let the chamber heat up or cool down to the defined safety temperature
range.
The press down RESET button (5) “RESET CL 2.0” located in the lat-
eral control panel to re-activate the chamber. The red pilot lamp K1
goes off.
Then reset the alarm message at the controller display by controller
button RESET (chap. 13).
