COMMISSIONING

Before commissioning, the plant-specific and process-specific safety measures must be observed.
N O T E !
The following steps must be carried out before initial commissioning:
Plug the power plug of the supplied power cable into the power socket;
•
Connect the heated cable (optional);
•
W A R N I N G !
Connect the mains plug to the mains;
•
• Switch the main switch to position 'I'.
• Set the desired temperature on the temperature controller.
Type 701: The digital display of the controller shows the actual value of the heated sample line after
switching on the sample gas conditioning unit. The controller is set to 0 °C [32 °F] on delivery. Briefly
press the P key to change the set point. SP appears in the display and then the display changes to
the adjusted set point. Use the arrow keys to set the desired value. After 60 seconds, the display
automatically changes to the actual value.
The sample gas cooler is ready for operation after approx. 10 minutes. The overtemperature alarm
contact of the cooler switches on the sample gas pump automatically when the cooler reaches the
temperature of +8°C [46.4 °F].

Before connecting the equipment to the supply voltage, the
main switch must be in position "0".
When operating the sample gas conditioning system with a
heated sample gas line, the temperature must be checked at the
temperature controller.
The following minimum gas flow rates result from the requirement
of the maximum pressure-side load of the sample gas pumps N3
KPE and N9 KPE of 1.4 bar abs:
N 3 KPE approx. 60l/h air,
N 9 KPE approx. 200l/h air.
If the required minimum total flow rate is not reached, excessive
overpressure can lead to premature destruction of the pump
diaphragm.
For long-term measurements with a high dust content in the
sample gas, a suitable gas sampling probe must be provided to
protect the sampling line from blockages.
