The booster can then be started and stopped using the MB menu item from the

running.
9.7.2 Changing the booster me delay
The me delay for starng the booster in automac mode can be congured using the
BP start delay menu item to between 1 and 200 seconds.
Note:
It is not recommended to set the delay to less than 20 seconds when the booster is
starng aer the dry pump.
9.7.3 Seng the booster to start when the inlet isolaon valve is open
To reduce energy consumpon the booster can be congured to only run when the inlet
isolaon valve is open. The inlet isolaon valve automacally opens when the dry pump
is on‑process and is closed in Green mode/standby mode.
To congure the booster to only be on when the inlet isolaon valve is open, use the BP
delay aer menu item and set the opon to Isol valve.
9.8 How to congure pump behaviour
9.8.1 Smart Stop
The pump has a congurable intelligent shutdown behaviour mode called Smart Stop.
When Smart Stop is enabled, the speed of the pump is ramped down gradually to allow
the pump to cool down before stopping. The intenon is to allow condensible process
chemicals to be pumped away without jamming the pump mechanism.
The following ow chart shows how Smart Stop operates:
