6-2 Options for Pump Setup
The ramp time represents the amount of time it takes for the vacuum blower to come up to full speed once it has been turned on. The ramp down time represents the amount of time it takes the blower to stop once it has been turned off.
The ramp up time lets the blower reach full speed unloaded. When the ramp up time is reached, the vent valve will open and allow the pump to draw a vacuum on the main vacuum line. This in turn will open the receiver sequence valve connected to the main vacuum line and allow material to be drawn into the vacuum receiver.
The ramp down time allows the vacuum blower to come to a full stop before it can be started again. This prevents the blower motor from becoming a generator and blowing fuses.
