7 Configurable Settings
This section describes the proper setup of the SCC4-38
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.

7-1 Options for Station Setup

Name Description Options Default
Conveying Options
Convey time 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.)
Adjust this value to match the actual time needed
to fill the station.
1–999 sec. 30 sec.
(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.
——
Unload delay Length of time allowed for material to drain from
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.
1–99 sec. 10 sec.

convey material to station (Requires additional
optional equipment.)
