10. Temperature safety devices
10.1 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 approx. 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.
10.2 Overtemperature safety controller class 3.1
The chambers are regularly equipped with an electronic overtemperature safety controller (temperature
safety device class 3.1 according to DIN 12880:2007). If an error occurs, the safety controller performs a
regulatory function.
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).
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 value. This condition (state of alarm) is indicated visually and
additionally with an audible alert if the buzzer is enabled (chap. 13.2). The alarm persists until the chamber
cools down below the configured safety controller value and the alarm is reset on the controller.
Check the setting regularly and adjust it following changes of the temperature set-point or
charge.
The safety controller only activates after the set-point has been reached once.
