1 Installation.
1.1 Installation Overview.
Since there are many makes, models and vintages of blow moulding machines it is impossible to give specific
instructions as to the mounting, wiring and plumbing schemes to use. Different machines have different
requirements that the installer must ascertain before beginning the actual physical installation of the system. A
careful examination of the machine and some thoughtful planning beforehand will usually produce a good,
serviceable installation. There are some suggestions that hopefully will make your installation smooth and provide
many years of trouble free operation.
It is recommended that, if space is available on the machine, the programmer and its various electrical components
b
e mounted in a separate enclosure. While it might be possible to mount these components in the machine’s main
electrical cabinet, quite a bit of electrical “noise” and heat is usually generated there. While the Parison Controller
was designed with some degree of tolerance for these conditions it must be remembered that it is, in essence, a
computer.
To minimize any detrimental effects on the system that can be sometimes caused in such an environment, it may
be easier and wiser to circumvent any problems
before they are created. The old adage “An ounce of prevention…”
can definitely apply here.
If using a separate enclosure or not, thoughtful layout of components is quite important. Remember, for future
troubleshooting it is important to consider accessibility to terminals to allow for voltage readings and the ability to
reach fasteners so components can be removed and replaced. Cable routing should also be considered to prevent
stretching of cables, straining of connections, pinch points and sharp edges that could damage a wire or cable.
Transducer and valve cables should be run through a “Seal-Tite” type of flexible, liquid tight conduit. Although it is
much faster and easier to run them over the machine unprotected, enclosing them in conduit provides protection
against physical damage as well as protection against insulation breakdown due to airborne chemical.
Cabling should also be run away from sources of heat (extruders, accumulators, and heater bands) and strong
electrical fields (motors, transformers, etc.).
The programmer can be mounted anywhere convenient to the operator station but should be located away from
areas where it could be damaged by falling objects or flooded by broken coolant or hydraulic lines.
Cable lengths to valves and transducers should be kept as short as possible to minimize line loss and signal
corruption, but long enough to provide movement of machine members for unrestricted operation and machine
maintenance. When routing cables it is wiser to avoid possible noise sources or areas of potential damage than to
minimize cable lengths.
