9. Observe the following:
• horizontal and vertical alignment of the gas sampling
probe in relation to the opening in the mounting flange
• stability of the probe retractor fastening elements
• unobstructed mobility of all cable and hose connections
• even movement of the probe buggy
10. Wait for cooling water to heat up to see that the cooling
system is performing correctly.
After inserting the probe, the complete system is ready to
sample because the probe is equipped with internal electrical
heating of the gas-conducting tube.
11. Switch the gas sampling probe to automatic mode using the
HMI Home page.
Result
The sampling system is thus in automatic mode and monitors
itself.
Checking the direction of rotation of the heat exchanger
After first insertion with the water temperature up at normal (70
to 75 °C), check the direction of rotation of the fans at the heat
exchanger of the water cooler:
The rotor of the two fan motors must turn according to the
arrow on the unit. If necessary, adjust the direction of rotation
by shifting position of two of the phase on the power supply.
