On‑process ramp is enabled by setting a ramp delay time greater than zero. This time is
the time delay between the pump speed increases. The ramp step size determines the
size of each step. The pump speed will not exceed the maximum allowed pump speed.

9.9 How to set up the DP clean

The DP clean set sequence can be used to clean the dry pump of systems that are fitted
with the high flow purge and solvent flush kit.
Before using DP clean, ensure that the high flow purge and solvent flush kit is set up as
described in High flow purge and solvent flush set up on page 51. Also, refer to Dry pump
clean on page 63.
The DP clean process is run while the dry pump is in Green mode/standby mode. By
default, the DP Clean runs for 20 minutes with the dry pump running at 80 Hz with no
inlet purge.
The following flow chart shows the functional behaviour of dry pump clean:
