RPV (Remote

This option allows the system to use a remote

disabled,

disabled

Proportioning Valve)

proportioning valve to mix two different

enabled PLC,

 

 

materials, typically virgin and regrind materials,

enabled local

 

 

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

0 –100%

30%

 

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.

 

 

Cycle time

Number of seconds for each cycle in depositing

5–100 sec.

10 sec.

 

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.
