1. From the SETUP menu, scroll down and select the Set Sequences menu.
2. Scroll down and select BP Start Options.
3. Select BP Start Mode...
4. Select Manual.
The booster can then be started and stopped using the MB menu item from the
Commands menu. Refer to
page 158.
Note:
If booster is manually controlled and dry pump is stopped then the booster will continue
running.

9.7.2 Changing the booster time delay

The time delay for starting the booster in automatic mode can be configured 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
starting after the dry pump.

9.7.3 Setting the booster to start when the inlet isolation valve is open

To reduce energy consumption the booster can be configured to only run when the inlet
isolation valve is open. The inlet isolation valve automatically opens when the dry pump
is on‑process and is closed in Green mode/standby mode.
To configure the booster to only be on when the inlet isolation valve is open, use the BP
delay after menu item and set the option to Isol valve.

9.8 How to configure pump behaviour

9.8.1 Smart Stop

The pump has a configurable 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 intention is to allow condensible process
chemicals to be pumped away without jamming the pump mechanism.
The following flow chart shows how Smart Stop operates:
