Wiring a Continuous-extrusion Machine
This setup has four identical injection units. Wire all four channels the same with
these I/O devices:
•
analog output to the valve amplifier for the parison die head
•
LVDT position input from the parison die head
Wiring a Reciprocating Screw Machine with Single Accumulator
This setup has a single accumulator driving four identical injection units. Wire all
four channels the same (see continuous extrusion, above) with these I/O devices:
•
analog output to the valve amplifier for the parison die head
•
LVDT position input from the parison die head
Wire the actuator for analog I/O signals from a fast-analog I/O module such as
1746-FIO4V (for voltage-level signals) in the SLC I/O chassis.
IMPORTANT
If multiple power sources can be used, do not exceed the
specified isolation voltage.
