Temperature safety devices
7.1
Electric safety controller (temperature safety device class 3.1)
The sample conditioning cabinet is equipped with an electric over temperature safety device class 3.1
acc. to DIN 12880. It is called “safety controller”. It serves to protect the charging material against
extensive high temperatures.
The safety controller is electrically independent from the main temperature controller and takes over
control when a selectable maximum temperature is reached. This maximum temperature is to be set at
the controller via the parameter “Al.5” (Table 3 on page 30 or Table 4 on page 31).
In case the safety controller is activated, an “absolute limit alarm” is triggered (chapter 8.1.1 on page 35).
On the upper controller display the message “otc” and the current interior temperature are displayed
alternately. Heating, humidification, and illumination (only CONDITIONER
TM
with lighting unit) are
automatically switched off and an alarm sound is emitted which can be muted by hitting controller button
.
When the interior temperature drops by 1°C below the value of the parameter “Al.5”, the absolute limit
alarm is terminated and the heating resets automatically. On the upper display the current interior
temperature is displayed only.
The necessary actions to be taken, if an absolute limit alarm occurs are described in chapter
8.1.1 on page 35)
