Commissioning; Cooler Control - M&C CSS Series Instruction Manual

13 COMMISSIONING

Before commissioning, the plant-specific and process-specific safety measures must be observed.
Before switching on the power supply, check again that the operating voltage (see type plate) and the
mains voltage match!
Follow these steps before starting up the device 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 mains plug to the mains;
• Switch on power.
After the starting time (LED K1 on the controller is on), the gas conditioning system is ready for use, and
the sample gas pump is switched on. Only now the sample gas can be fed.
The following minimum gas flow rates result from the requirement not to limit
the sample gas pump to less than 20 % of its maximum capacity:
N3 KPE min. 30 Nl/h air
N O T E !
N5 KPE min. 60 Nl/h air
N9 KPE min. 110 Nl/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.
