6.4.1 Measures before initial commissioning
Are the preconditions for operation satisfied?
Is the supplied dust measuring probe suitable for the existing duct in
respect of its gas flow orientation (horizontal, vertical flow direction,
see section Equipment on page 38)?
For a system that has been correctly configured and installed the red
dots on the probe flange and the welded-in flange should be alongside
each other in the upper position.
□
Is the connection cable with the plug connector plugged into the
measuring probe and secured with the cap nut?
□
Is the supply unit installed and supplied with power?
□
Has the cabling work, as described in section
