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.)

Dump delay 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 dump delay should match the times actually required to fill
and empty the station. The following problems may occur if these settings are incorrect:
and empty the station. The following problems may occur if these settings are incorrect:
1. Material is backing up and causing “high vacuum” alarms (for time-fill stations
only): Convey time is too long.
2. 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 n Operator screen shows the length of time the controller

Activating and Stopping Priority Convey for a Station
Before activating priority convey, make sure that all other stations using the same pump have
adequate material in reserve to continue operation. No material will be conveyed to these
stations during priority convey.
adequate material in reserve to continue operation. No material will be conveyed to these
stations during priority convey.
If you want the controller to fill a specific station with material immediately, you can activate
“priority convey” for that station. When you do so, the controller temporarily dedicates the
station’s pump to it, ignoring demands from other stations assigned to that pump. Once the
chosen station is full, normal operation resumes.

You can also use this feature to give one station a “head start” by conveying a few loads to it
and then stopping the priority convey.

No more than one station for a given pump can be in “priority convey” at once.
