Abstract (en)
[origin: EP0689018A1] The unit (10) has a green signal lamp (L1) for normal operation, a yellow signal lamp (L2) for continuous operation and a red signal lamp (L3) for indicating an abnormal condition. A piezoelectric buzzer (20) provides a warning signal tone when the temp rises above a given threshold value, the red signal lamp acting as the oscillation generator for the piezoelectric buzzer. The 3 signal lamps are combined with the rapid-freezing switch (12) and the piezoelectric buzzer in a plug-in module, the green and yellow signal lamps coupled to the refrigeration motor and the red signal lamp to a temp. sensor, when the module is fitted in the refrigeration device. <IMAGE>
