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.

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. 
0–999.9 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.

Dump 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.
