13.3.1 Temperature safety device class 3.1
If you turn the control knob (8) to its end-stop (position 10), the safety device
class 3.1 protects the appliance. If you set the temperature a little above the
set-point, it protects the charging material.
If the safety device class 3.1 has taken over control, identifiable by the red
alarm lamp (8a) lighting up, the message “
Temp. safety device ” on the
controller will be displayed and the buzzer will sound, then proceed as fol-
lows:
•
Reset the buzzer by pressing the “RESET” key on the controller
•
Disconnect the chamber from the power supply
•
Have an expert examine and rectify the cause of the fault.
•
Start up the chamber again
Setting:
To check the response temperature of the safety device class 3.1, turn on the chamber and set the de-
sired set point at the temperature controller.
The sections of the scale from 1 to 10 correspond to the temperature range from 0 °C / 32 °F to 120 °C /
248 °F and serve as a setting aid.
•
Turn the control knob (8) of the safety device using a coin to its end-stop (posi-
tion 10) (chamber protection).
•
When the set point is reached, turn back the control knob (8) until its trip point
(turn it counter-clockwise).
•
The trip point is identifiable by the red alarm lamp (8a), the message “ Temp.
safety device ” on the controller display, and the buzzer sounds. Reset the
buzzer with the “RESET” key on the controller.
•
The optimum setting for the safety device is obtained by turning the control
knob clockwise by approximately two scale divisions, which shuts off the red
alarm lamp (8a).

Function check:
Check the temperature safety device class 3.1 at appropriate intervals for its functionality. It is recom-
mended that the authorized operating personnel should perform such a check, e.g., before starting a
longer work procedure.
