3 Installing specifications
The equipment was designed and built for the regulation of “hot runner systems” through the
control of electrical energy supplied to the heating elements of the various parts of the system
(distributors, nozzles, ….) with the aim of keeping process temperatures stable (max
temperature 400°C).
The apparatus allows independent control of each zone.
The control and power connectors (TC) are positioned on the rear panel of the equipment.
The maximum nominal value for the current through each heating zone is 16A.
The maximum nominal value for the current through each “nozzle” zone is 3A.
This is a quite complex apparatus hence its life and reliability are guaranteed only if it is
correctly used and maintained.
Carefully read the advice supplied in this manual because it contains important information
regarding the safety of installation, use and maintenance.
Check the integrity of the apparatus once the packaging is removed. In case of doubt do not
use it and refer to the supplier.
Before connecting the apparatus, check that the specifications of the plate correspond to
those of the electricity supply (the plate is situated at the back of the machine).
This apparatus must be employed solely for the use for which it was specifically
designed, i.e. for the regulation and control of a “hot runner” system of which it is an
integral part. Any other use is to be considered improper and therefore dangerous
.
The manufacturer cannot be considered responsible for any damages sustained resulting from
improper, erroneous and/or unreasonable use.
The electrical safety of this apparatus is assured only when connected to an effective ground
(as set out by current regulations). The manufacturer denies responsibility for any damages to
persons or objects resulting from the lack or inadequacy of the ground of this apparatus.
Normally the differential protection device is not included in the controller. This device must
be installed in the main electric supply system.
Ensure that the capacity of the power socket is compatible with the maximum power of the
apparatus (indicated on the plate) and that the local electrical installation satisfies regulations
and in particular: CEI 44-5 (EN 60204-1) art. 7.2.1-7.2.6. and CEI 64-8 art. 473.3.2.1 and art. 7.
3.1 Special warnings
•
Ensure that moving parts cannot damage the controller or its connection cables.
•
Since the controller is a highly ventilated piece of equipment, it needs to be positioned
such that free circulation of airflow is enabled, therefore leave ample air spaces to allow
the free flow of air.
•
Before starting the system, pay special attention to how the supply to the controller is
wired and how it is connected to the mould. Incorrect wiring of main supply phases
into the controller can seriously damage electronic components. Crossing heater
supply looms with thermocouples looms will produce damage to thermocouples
looms or to the thermocouples (inside the mould) themselves.
The manufacturer cannot be considered responsible for damage caused to the controller and to
the mould by customer wiring and connection errors.
