Chapter 4: Operation

4-1 Overview

Your 1-pump, 9-station controller electrically controls valves and solenoids to convey material from a central location to individual stations as needed. The controller senses demands for material at the stations and responds to the demands in a timely fashion.

This section provides the procedures necessary for using your controller.

Note: Before you carry out any of the procedures in this chapter, the system must be set up as described in Chapter 3.

4-2 Starting and Stopping the System

1.Press F1 to start the conveying system. The controller will display “F1 SYS ON” in the upper left corner of the Main Menu screen.

Note: The conveying system can also be activated by pressing the F1 key when in the Status screen. The controller will display “F1 SYS ON”in the middle of the bottom of the screen.

Once the system has been started, each active station is polled in sequence for a demand signal. The convey sequence upon initiation, will continue until the set convey time has elapsed or the demand signal stops, whichever happens first. If the Special Timed Convey feature is enabled, conveying will continue until the convey time has elapsed. (Once station dump delay has been initiated during the convey sequence, a new demand signal will be ignored.) If the blowback sequence begins immediately following the convey sequence, the sequence valve will remain open throughout the blowback sequence.

2.To stop conveying, press F1 again when in the Main Menu or Status screen. The controller will display “F1 SYS OFF.”

4-3 Alarms

No Convey

If no convey is enabled and the station conveys the specified number of times unsuccessfully, the alarm horn/light will activate. The status for that station will display “NO CNVY.” If the station is currently in convey or unload, the status will alternate between “NO CNVY” and “CONVEY” or “UNLOAD.” Pressing F2 while the status screen is displayed will silence the alarm. The status screen will continue to show “NO CNVY” until a successful convey occurs.

High Vacuum

If a high vacuum condition is detected during the convey sequence, the alarm horn/light will activate. The status for the affected station will display “HI VAC.” If the station is currently in convey or unload, the status will alternate between “HI VAC” and “CONVEY” or “UNLOAD.” Pressing F2 while the status screen is displayed will silence the alarm. The status screen will continue to show “HI VAC” until a convey occurs where no high vacuum condition is sensed.
