PARISON CONTROLLER

2.5.3 Elements.
PARISON CONTROLLER can be configured to manage up to 4 heads.
Each regulator uses an analog input to acquire the mandrel opening and an analog output to drive the mandrel
positioning actuator.
The regulator can operate in closed loop (with no-intelligent actuators) or in open loop (with intelligent actuators
that operate in closed loop stand alone).
The input value is calibrated in range 0% - 100.00% through definition of upper extreme voltage and lower extreme
voltage. In case of intelligent actuators the calibration points are set to 0 mV and 10000 mV if it is not necessary to
make the calibration.
PARISON CONTROLLER can be configured to manage 1 accumulator.
A regulator in position in accumulation mode requires that the accumulator management is setup on fourth channel.
The setpoint generated by thickness regulator depends on the accumulator position in injection stroke relating to
the total injection stroke.
Input value is calibrated in range 0% - 100.00% through definition of full accumulator voltage (100% and input
higher than empty position) and empty accumulator voltage (0% and input lower than full position).
It is possible to
exchange the analog output polarity to ignore the actuator connection polarity. The default polarity value waits for
increasing voltage values to bring the accumulator to empty position.
The input calibration should be made in this way:
It is possible to indicate a voltage to be applied on extrusion control output and activate empty accumulator
calibration procedure. The system automatically detects mechanical end-of-stroke, stores this value and interrupts
extrusion control. Using manual methods, the accumulator should be brought to empty and full position and it is
possible to manually confirm the positions.
PARISON CONTROLLER can be configured to manage up to 2 extruders.
It is possible to decide whether to use the extruder or not and which channel it should be associated to. It can be
associated to:

A thickness regulator in continuous extrusion.

A thickness regulator in time accumulation.

Accumulator.
It is possible to decide whether the extruder is driven by an analog or digital command. In case of analog command
the output voltage of a channel is the speed setpoint. In case of a digital command two digital outputs allow increase
or decrease of speed.

Extruder with analog command:
o
It is possible to calibrate the input with: 0 speed voltage, maximum voltage, and maximum speed.
The speed is expressed in RPM.
o
It is possible to calibrate the output with: maximum speed, voltage to reach maximum speed.
o
These setpoints can be setup: speed to be reached, rising ramp in RMP/sec., falling ramp in
RPM/sec., minimum speed, maximum speed.

Extruder with digital command:
o
You can setup the maximum ON time for digital output depending on a manual command.
Timer Switch
The Parison Controller can manage a weekly timer switch to activate the machine heating system and it can
manage a production counter.
