
Insert the mains cable coming from the external temperature controller (min. 3 x 1.5 mm²)
through the threaded cable gland and connect to the appropriate terminals.

14 STARTING

Before starting up check whether the mains power supply voltage corresponds with the infor-
mation stated on the probe's nameplate.

Check the rated value setting on the built-in thermostat or on the external controller.

Switch on mains power supply. The total heating-up time is approximately 2 hours. After about
1 hour the probe is already sufficiently heated for the temperature to have exceeded the tem-
perature failure alarm value (30°C below rated value), but it still takes about another hour until
operating temperature is reached.

The sample gas can now be extracted via the probe after this minimum heating-up time of 2
hours.
