Adjusting Convey Time and Dump Delay
Convey time is the length of time the station’s vacuum valve 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.)

Unload time is the length of time allowed for material to drain from the station into its
receiver. During this time, the controller does not attempt to deliver any more material to the
station.

The settings for convey time and unload time should match the times actually required to fill
and empty the station. The following problems may occur if these settings are incorrect:

•  Material is backing up and causing “high vacuum” alarms (for time-fill stations only):

Convey time is too long.

•  System is not keeping up with the demand for material: Convey time is too short, or

dump delay is too long.

For your reference, the “Station Operator” screen shows the length of time the controller
actually spent conveying material during the most recent delivery under Last Convey.

To adjust a station’s convey time (or the unload time), complete the following steps:

1.  Go to the “Station Operator” screen by touching and holding a station icon, or go to the

“Station Setup” screen.

2. 

Touch CONVEY TIME.  A keypad pops up.

3. 

Enter the number of seconds desired for convey time or unload time. Use CLR to erase
any mistakes. Use ENT to enter the value. The new setting appears under CONVEY
TIME (or UNLOAD TIME).
