Installation of HPS III valve gate hot runner systems
1. Check the clearance
∆S
between the surface (B) of the
outer collar of the drive unit and the surface of the nozzle
retainer frame plate (pos. 53) and compare it to the va-
lue given in the drawing provided by EWIKON.
2. Install the clamping plate (pos. 51).
3. Connect the supply lines for compressed air to the drive
units and place them in the corresponding cutouts in the
clamping plate. For more information regarding connec-
tions and accessories see the EWIKON valve gate main
catalogue.
4. Install the insulating plate (pos. 50).
5.
Install the locating ring (pos. 6) and fix it with socket
head screws (pos. 6.1, ISO 4762 - 12.9). Tighten with
matching torque. See chapter
„9. Tightening torques“.
6. Wire the nozzles and the manifold according to the
wiring scheme. Please pay attention to the notes in
chapter „5.6 Electrical connection of hot runner sys-
tems“.
7. In order to clearly identify the hot runner system attach
the type plate included in the delivery prominently to the
operator side of the mould.

Connected power supply during installation
Risk of deadly electric shock or severe injuries due to live compo-
nents.
• The hot runner system and the mould have to be disconnected
from the voltage source during installation.
HAZARD!
Sharp edges and heavy components
• Cut injuries to body and extremities, mainly to the hands.
•
Crushing of fingers or hand.
Control of live components before installation
The electrical equipment of the hot runner system should be
checked, especially those areas which will no longer be accessible
after installation. Physical injuries such as an electric shock can be
prevented that way.
Please check
• if cables are kinked or squeezed.
• if cable insulations are undamaged.
Pressurised systems
During installation all hydraulic or pneumatic supply lines must be de-
pressurised.
•
Injuries caused by flying parts or "whipping" hoses.
• Injuries to eyes caused by escaping pressurised liquids.
WARNING!
All clearances must be checked in cold condition!
In case of deviatons the clearances must be adjusted in an appro-
priate way (e.g. by machining the nozzle retainer frame plate or the
pressure pads of the manifold).
Attention:
The adjustment must not have influence on the dimension
X of the nozzle!
Checking of clearance when using nozzles for front installation
When nozzles for front installation are installed the contour pla-
te (pos. 56) must be installed before the clearance ΔS is checked.
Otherwise the measurement is falsified.
NOTE!
