Appendix A2
The following menus are used by the PDT to configure Smart stop:
Figure A46 - 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 whilst 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.
A2.8.2 How to configure ramped speed increase
The GXS pump has a configurable intelligent on-process behaviour mode called on-process Ramp. When on-process
Ramp is enabled the speed of the pump is ramped up gradually when accelerating from Green Mode/Standby speed
to 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: On-Process Ramp is only effective if an Green Mode/Standby speed of less than full speed has been set.
Contact Edwards for more information about configuring Green Mode/Standby speed.
