Make sure that the following sequence is observed:
✓
You have performed all of the steps listed in chapter
Putting the FCU into operation [
}
41] .
To guarantee valid and direct measurements,
prime the FCU. To do this, draw in approx. 120
ml fluid via the inlet hose in order to completely
fill the hydraulic circuit and the inlet hose.
If the FCU is not primed, an air-oil mixture at
the start of measurement will flow through the
FCU. The sensor will interpret this air-oil
mixture as par- ticulate soiling and will thus
falsify the measure- ment result.
For an initial test without priming the FCU
and hoses, you need ≥ 300 ml of fluid.
