24-Pump, 128-Station Controller Chapter 6: Configurable Settings 68
Name Description Options Default
RPV (Remote
Proportioning Valve)
This option allows the system to use a remote
proportioning valve to mix two different
materials, typically virgin and regrind materials,
during a convey cycle. Touching RPV repeatedly
at the Station n Setup screen steps through the
three choices.
Enable this option with PLC control if you will be
adjusting the mix from the controller’s touch
screen.
Enable this option with local control if the station
operator will be adjusting the mix using a timer
box at the station.

RPV material B Percentage of the additive material to be
included in the mix. This setting applies only
when RPV is enabled with PLC control. The
system is set up so that, if there are any
inaccuracies in the proportions, the mix will
contain more Material A and less Material B
than specified here.
0 –100% 30%
Cycle time Number of seconds for each cycle in depositing
Material A and Material B during the convey
time. This setting applies only when RPV is
enabled with PLC control. Example: If you set
convey time to 30 seconds, cycle time to 10
seconds, and Material B to 30% (so Material A
is 70%), the system will convey as follows:
Material A for 7 seconds
Material B for 3 seconds (end cycle 1)
Material A for 7 seconds
Material B for 3 seconds (end cycle 2)
Material A for 7 seconds
Material B for 3 seconds (end cycle 3)
In a volume-fill station, a cycle will be truncated
before completion if the station becomes full.
The cycle time should divide evenly into the
convey time.
