Overtemperature protection

Overtemperature protective device (class 1)

The chambers are regularly equipped with an overtemperature protective device (safety device class 1
acc. to DIN 12880:2007). It serves to protect the chamber, its environment and the contents against ex-
ceeding the maximum permissible temperature. When a defined temperature is reached, which is approx.
by 20 °C to 30 °C above the chamber's nominal temperature, the overtemperature protective device turns
off the heating.
Cut-off temperature values:
BD, BF: 120 °C
ED 260: 320 °C
ED 56, ED 115, FD 56, FED 56: 330 °C
FD 115, FD 260, FED 115, FED 260: 350 °C
The message "Overtemperature" is displayed on the controller.
If the overtemperature protective device class 1 has turned off the heating, proceed as follows:
• Disconnect the chamber from the power supply for at least 10 seconds (pull the power plug).
• If appropriate, have an expert examine and rectify the cause of the fault .
• Let the chamber cool down
•
Restart the chamber.
As soon as the inner chamber temperature after restart is below the defined cut-off temperature of the
overtemperature protective device class 1, the alarm message is deleted automatically.
Reset temperature values:
BD, BF: 90 °C
ED 260: 220 °C
ED 56, ED 115, FD 56, FED 56: 230 °C
FD 115, FD 260, FED 115, FED 260: 250 °C
