Checking operating states and sensors (diagnostics)
Depending on the previous setting, other displays will
be available.
Check temperature values or states of all inputs for
"function and logic".
Examples of "function and logic":
■ Are the temperature values of the sensors in the nor-
mal range?
■ Is the state of the maintenance cover ("Open" or
"OK") correct?
Is the state of the light barrier ("Full" or "Empty") cor-
■
rect?
Residual oxygen content OK?
