COMMISIONING

Observe the facility and process-specific safety measures before commissioning.
Carry out the following steps before initial commissioning:
1. Connect the cable to the terminal mounting rail.
2. Connect the heated sample line (optionally).
Warning
3. Set the desired temperature on the temperature controller.
Type 701 (effective from: September 2020, Serial No. 2009143):
After switching on, the display of the controller shows the actual value and the setpoint of the heated line.
On delivery, the set point is set to 0 °C [32 °F].
To change the set point, press one of the arrow keys to adjust the desired set point.
Note
The gas cooler is ready for operation after approximately 3 minutes. If a heated line is connected, the time in
which the gas conditioning unit is ready for operation increases to approx. 1 hour.
The over temperature alarm contact of the cooler switches the sample gas pump automatically on as soon as
the temperature reaches +8 °C [46.4 °F].

Check the temperature at the temperature controller when operating the
sample gas conditioning unit with a heated sample gas line
The complete instruction manual of the temperature controller 701 is
available at www.mc-techgroup.com.
The following minimum gas flow rates result from the requirement of the
maximum pressure-side load of the sample gas pumps N3 KPE, N5 KPE and
N9-KPE of 1.4 bar abs.:
N3 KPE approximately 60 Nl/h air,
N5 KPE approximately 100 Nl/h air,
N9 KPE approximately 200 Nl/h air.
Premature damage can be caused to the pump membrane if less than the
minimal total amount of flow is extracted as a result of over pressure.
For long-term measurements with a high dust content in the sample gas, a
suitable gas sampling probe must be provided to protect the sample line
from being clogged.
