17. Temperature safety devices
17.1 Over temperature protective device (class 1)
The chamber is equipped with an internal temperature safety device class 1 acc. to DIN 12880:2007. It
serves to protect the chamber and prevents dangerous conditions caused by major defects.
If a temperature of about 110 °C / 230°F is reached, the over temperature protective device permanently
turns off the chamber. The user cannot restart the device again. The protective cut-off device is located
internally. Only a service specialist can replace it. Therefore, please contact an authorized service provider
or BINDER Service.
17.2 Overtemperature safety controller (temperature safety device class 3.1)
The chamber is regularly equipped with an electronic overtemperature safety controller (temperature safety
device class 3.1 according to DIN 12880:2007).
The overtemperature safety controller serves to protect the chamber, its environment and the contents from
exceeding the maximum permissible temperature. In the case of an error, it limits the temperature inside
the chamber to the entered safety controller set-point.
Please observe the regulations applicable to your country (for Germany: DGUV guidelines 213-850 on safe
working in laboratories, issued by the employers’ liability insurance association).
Set the safety controller set point by approx. 2 °C up to 5 °C above the desired temperature set point.
Recommended setting: Set-point type “Offset” with safety controller set-point 2 °C (factory setting).
The safety controller is functionally and electrically independent of the temperature control system. If an
error occurs, it performs a regulatory function.
Check the setting regularly and adjust it following changes of the set-point or charge.
The safety controller only activates after the set-point has been reached once.
