The Control
Systems
The control systems
supervise the various functions of the machines and automatically conducts
the logical sequence of operational phases. The elements of the
control system are:
Machine
Controls:
Preset management of operating thresholds optimizes the consumption of
utilities and permits an overlap of machine functions.
Integrated
Quality Assurance:
The quality of extrusion is maintained through control of extrusion
barrel and head temperature, extruder speed, parison thickness profile and
parison length. Trends are controlled and automatically corrected to
optimize product quality.
Production Controls:
Automatic start-up and shut down of extruder heaters and automatic stop of
the machine under certain alarm conditions facilitate operation.

Maintenance and Trouble Shooting: Over 100 alarm conditions have been programmed and necessary preventive maintenance needs are automatically signalled. An extensive diagnostics system for verification of input and output signals facilitates troubleshooting.
The control system has facility of connecting MODEM for remotediagnosis and trouble shooting of the machine. This facility could save machine down time.
Data Input and Output: The Video unit with multi language support and incorporated keyboard, allows direct and simple access to facilitate programming, visualization of information in graphic and alphanumeric format and connection to an external printer. The adjustable machine parameters include screw speed, barrel temperature, carriage movement stroke, various time delays and parison thickness control. Complete sets of operating parameters can be memorized on the Modreg external storage facility and can be input into the PLC when changing the type of plastic material or bottle format.
