•
After tightening the connecting nuts by hand, tighten them a further 1 1/4 turns using a flat
spanner.
•
Push the end of the heated sample line as far as the end of the threaded connection joint and
clamp with the aluminium heat-conducting jaws.
•
Mount the aluminium heat-conducting jaws in the longitudinal axis of the filter chamber in such
a way that they fit into the aperture in the heat-insulated protective casing.
•
Remove the front part of the tension clip for holding the heated sampling tube to the probe and
push the filter chamber including the heated sampling probe into the heat-insulated protective
casing.
•
Screw on the front part of the tension clip again.
•
In the case of the PSP4000-H screw down the black knob on the rear side of the protective
casing and tighten by hand.
•
In the case of the PSP4000-H/C , PSP4000-H/C/T, the flat nut and the dummy bolt of the
threaded connecting joint on the rear side are to be screwed on again and after tightening the
dummy bolt by hand, this is then to be tightened further by turning precisely 1 1/4 turns with a
flat spanner.
14.2 ELECTRICAL CONNECTION
•
Plug in the 7-pin plug (power supply) and switch on the power. During the heating up phase, the
green control lamp glows. When the operating temperature is reached (180 °C [356 °F]), the
green control light is extinguished and then lights up when the heating element is switched on
to adjust the temperature.
•
For safety reasons, we recommend switching the gas pump on only after another fifteen minutes
has elapsed in order to ensure that the sampling probe heats up completely.
When using the
SP34-H... heated sample tube, the electrical connection should be made separately
using the built-in connection socket. The SP34-H sample tube has a built-in capillary tube thermostat
which adjusts the temperature in a range between 100 °C [212 °F] and 180 °C [356 °F]. (Factory setting
180 °C [356 °F]).
When using the heated sample tube
SP34-H1.1 and SP34-H2 , an external temperature controller is to
be used for adjusting the temperature.
14.3 CALIBRATION-GAS DISCHARGE
In the case of the probe version PSP400-H/C with integrated calibration-gas connection, test gas can
be conducted directly into the probe during the entire sampling procedure for the calibration of
connected gas-analysis devices.
•
Remove the threaded connection's dummy bolt on the rear side of the probe.
•
Connect the 6 mm stainless steel tube provided or a temperature resistant tube DN4/6 (PTFE,
Viton®, silicon) using the nut provided and the double clamping ring. When connecting the tube,
prior to assembly the 4 mm stainless steel insert must be pushed into the tube.
•
Introduce the tube or the hose into the threaded connection until it clicks in.
•
Tighten the threaded connection's nuts by hand and then exactly 1 1/4 turn using a flat spanner.
