Scaling and ramps of volume set values

2.4 Scaling and ramps of volume set values
This scaling defines the scaling-relationship between the voltage-value of the Q-Set fil-
tered (ZP177.35–) in respect to the output drive-speed (nSet). The nSet-value is then
sent to the ramp function generator (see
Figure 9:
2.5

Ramps pressure set values

The Ramp function generator (RFG) generates a function with rising and falling ramps.
The ramp up time can be defined in
pressure value to the pressure maximum value (ZP177.6–). The ramp down time can be
defined in
0 %.
