Gas sampling and gas conditioning technology 4-2.1.1-ME
Option temperature controller 701 for heated sample lines:
For the electrical supply and control of a heated sample line with PT-100 a 7-pin plug at the side is
available. The connection power is max. 6A, 1380W for the 230V version resp. 6A, 690W for the
115V-version.
The maximum length of the heated sample line which can be used is calculated as follows:
max. connection power [W] - power draw of heated components (i.e. sample probes) [w]
L(m)=
power draw of heated sample line [W/m]
13 STARTING
Before starting the gas conditioning system please pay attention to the site-oriented and process-
oriented precautions.
N O T E !
Before connecting the equipment to the supply voltage, the
main switch must be in position ‘0’ .
The following steps have to be done starting up the PSS-5... for the first time:

Place the cold appliance plug, which is delivered with the mains supply cable, into the cold
appliance plug socket;

Connect the heated sample line (option)!

Connect the mains plug to the power supply;
 Turn the main switch to the position ‘I’.

In case of option temperature controller 701 adjust the required temperature at the controller:
The digital display shows the actual temperature value of the heated line after switching on the
conditioning unit. The controller is adjusted to 0 °C by factory. To change the set temperature
press key P . The display shows S and than it changes to the adjusted set temperature.
Change the value with the arrow keys. After 60 seconds the display switches automatically to the
actual value.
The gas measuring cooler will become operational after approximately 10 minutes. The excess
temperature alarm contact located in the cooler switches the sample gas pump automatically on as
soon as the temperature reaches +8°C.
W A R N I N G !
Check the temperature at the temperature controller if the
conditioning unit is run with a heated sample line!
