Figure 61 Smart Stop PDT menu configuration items

▪ Smart Stop is enabled and disabled using the enable/disable menu item.
▪ The maximum time that the pump will run while shutting down is set using the
Stop time menu item.
▪ The size of the dry pump speed reductions is configured using the Step size menu
item. The time between speed step reductions is automatically calculated by the
software based on the size of the speed step reductions and the maximum time
the pump will run.
▪ The pump can be triggered to stop when its internal temperature reaches a certain
set point. Select the Setpoint menu to configure the set point temperature.
▪ The pump can be triggered to stop a certain time period after it has cooled to the
set point temperature. Select the Settle time menu to adjust the time period.

9.8.2 How to configure ramped speed increase

The pump has a configurable intelligent on‑process behaviour mode called on‑process
ramp. When the on‑process ramp is enabled, the speed of the pump is ramped up
gradually when accelerating from the green mode/standby speed to the process speed.
This gradual acceleration can prevent a large disturbance to the process load which
could result in a slug of process material being drawn into the pump.
Note:
‑ process ramp is only effective if the Green mode/standby speed of less than full
The on
speed has been set. Contact us for more information about configuring the Green mode/
standby speed.
The following menus are used by the PDT to on‑process ramp:
