
Draw the heating cartridge through the cable gland C (figure 21) out of the connection box.

Draw out the thermostat sensor through the cable gland in the opposite direction.

Mount the new thermostat and lead the thermostat sensor from inside through the cable gland.

Feed the new heating cartridge from outside through the cable gland.

Connect the electrical cables according to the connection plan (figure 9).

Mount the complete unit to the probe again.
The thermostat is equipped with a mechanical stop that limits the maximum temperature adjustable via the turning
knob.
When mounting the thermostat pay attention that the mechanical stop is mounted so that the arrow on the me-
tallic ring shows to the desired maximum temperature. (Standard adjustment 190 °C [374 °F]).

If you use gas sample probes with temperature sensor (PT100 or thermoelement) instead of the thermostat, lead
the sensor connecting cable with the heating cartridge through the cable gland. In order to do this, put the con-
necting cable into the corrugation of the sealing rings and the two metal rings.
18 SWITCHING OFF
Caution Before switching off, i.e. switching off the heating, the gas flow via probe has to be stopped and the
probe has to be flushed with inert gas or air in order to avoid condensation of aggressive compo-
nents from the process gas.
