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.

|
|
Idle | Length of time the pump continues to run unloaded without | 45 sec. |
(IDLE) | demand from any station. After this time has elapsed, the pump |
|
| shuts down to save power and to prevent wear on the pump. |
|
| Adjust this setting to fit the needs of your facility in trading off the |
|
| savings against the costs associated with waiting for a pump to |
|
| start up when there is a demand for material. |
|
Ramp Up | This feature specifies the time (in seconds) allowed for the pump | 5 sec. |
| motor to reach operating speed. |
|
Ramp Down | This feature specifies the time (in seconds) allowed for the pump | 5 sec. |
(Ramp Dn) | motor to come to a complete stop. |
|
Conveys Before | When this option is enabled, the controller periodically sends | enabled |
Blowback | compressed air backward through the pump’s air filter to dislodge |
|
(CNV>BB) | accumulated dust and debris. |
|
| Enable this option if and only if the pump has the equipment for |
|
|
| |
| Number of conveying cycles to stations between filter cleanings. | 5 |
| Adjust this setting based on experience. The more dust and |
|
| debris in your material line, the smaller this number needs to be. |
|
Pulse On Time | Tenths of seconds that the air pulse remains on for each cleaning | 1.6 sec. |
(BB ON) | pulse during filter cleaning. |
|
| If |

| ask you to change this setting. |
|
Pulse Off time | Tenths of seconds between air pulses during filter cleaning. | 0.8 sec. |
(BB OFF) | If |
|
| to change this setting. |
|
|
|
|
Numbler of cleaning | Number of pulses of compressed air sent through the pump’s | 1 |
pulses (No. Pulses) | filter during cleaning. |
|
(BB CYC) | If |
