Chapter 6: Configurable Settings

This section describes the proper setup of the 24-pump 128-station control system parameters. These parameters are operator changeable; however, these items should require setup only during the initial installation. Only authorized personnel should change them.

Many of the variables and setup parameters have been preset at the factory and do not need to be changed. However, this section of the manual will address all of the setup parameters that were available at the time of printing. The purpose of this is to familiarize the reader with all the setup parameters and their usage.

6-1 Memory Module Considerations

The operator interface and the PLC central processing unit use memory modules to store the operating program and user settings. The module is installed in the front of the PLC CPU card.

The memory module returns the controller to the factory default settings if an electrical fault occurs, or if the hardware is replaced. Keep in mind that this condition is extremely rare. You will then need to restore saved settings or set up the controller once again with the settings you programmed in this chapter.

6-2 Options for Station Setup

Name	Description	Options	Default
Conveying Options
Convey time	Length of time the station’s vacuum valve	0–999.9 sec.	30 sec.
	remains open to allow material to be drawn in.
	(For a volume-fill station, the valve closes when
	material covers the station’s volume-fill
	proximity sensor or this time elapses, whichever
	comes first.)
	Adjust this value to match the actual time
	needed to fill the station.
(Last convey time)	Display only. Length of time the station’s
	vacuum valve was open for receiving material
	during the most recent convey. This information	—	—
	is displayed for your reference when adjusting
	convey time and dump delay.
Dump delay	Length of time allowed for material to drain from	3–99 sec.	10 sec.
	the station into the receiver. The controller will
	not attempt to deliver more material to the
	station until this time has elapsed.
	Adjust this value to match the actual time
	needed to drain the station. If it is set too short,
	the controller may attempt to refill the station
	before it is empty, causing material to back up
	and/or underusing the station’s capacity. If it is
	set too long, the system may be unable to keep
	up with your equipment’s demand for material.
