2-1 Models Covered in This Manual

This manual provides operation, installation, and maintenance instructions for 24-Pump, 128- Station Conveying Controllers. Model numbers are listed on the serial tag. Make sure you know the model and serial number of your equipment before contacting the manufacturer for parts or service.

The 24-Pump, 128-Station Conveying Controller is a programmable logic controller, with 24 VDC control circuit, easy-to-use touch screen operator interface terminal and optional audible/visual alarm.

2-2 General Description

Our material conveying systems create vacuum for the automatic conveying of most free- flowing, dry, pelletized, or granular materials. Material characteristics determine the type of equipment needed to convey the material.

A typical use for our equipment is an in-plant distribution system for plastic processing plants.

Our central vacuum systems are as varied as the applications they service. The tubing and equipment furnished in our system is designed to convey the material(s) specified at the time of purchase at specific rates and distances.

We can advise you on your system capabilities based on system makeup, distance, material, and conveying rates you want.

System capacity is directly affected by the pressure drop in the overall system, such as number of material line bends, pipe length, Y-tubes, T-tubes, etc.

Use the minimum effective amount of vinyl flex hose to maximize material line efficiency. Keep material lines as straight as possible. Refer to the Mechanical Components Product manual (Part No. A0536580) for installation recommendations.

Note: Vacuum leaks occurring anywhere in your system reduce capacity.

2-3 Standard Features

Mechanical Features

Time-fill Capability. The specific length of time allowed for material to convey to a station.

Volume-fill Capability. Allows for a station to be conveyed to until the prox at the top of the station detects material.

Vent Valve. The vent valve unloads the vacuum pump motor and allows it to keep running during short periods when material conveying is not required. Constantly starting and stopping the vacuum pump will damage it over time. The vent valve also protects the conveying system from damage during high vacuum conditions. The valve plunger will unseat itself and allow ambient air to leak into the vacuum lines when the vacuum climbs too high.

Central Purging. This feature allows any remaining material to be cleaned out of the material line after every convey.

Local Blowback Filter Cleaning. When this feature is enabled, the controller periodically sends compressed air backward through the pump’s air filter to dislodge accumulated dust and debris.
