3.4 The Requirement Proceedings of the Installation Auxiliary
Functions
Because the electric flash is easily affected, so pay attention to the following items when
installing the auxiliary equipments.
3.4.1 The Grounding of the Auxiliary Equipments
The cables of the equipments, such as the unloading machine, hopper dryer and mold
temperature adjustor etc are concentrated on the main grounding terminator of the injection
molding machine. Thus, the injection molding machine and all the peripheral machines are
treated as the equal potential, it is added the safety and reduced the noise wave.
The reserved socket of the injection molding machine is a system based upon the
above-mentioned grounding cables, which is connected with the grounding terminal of the
injection molding machine, so if you use this socket, the grounding of the peripheral machines
will be easier.
3.4.2 The Grounding for the Noise Wave
It is recommended that separate the power of the injection molding machine and the other
machines (discharge processing machining, arc welding machine, commutator motor, and the
total number changeable equipment of the silicon controlled etc.) generated the noise wave, the
grounding system of the injection molding machine can not be shared a same place with the
abovementioned machines which may generate the noise wave. The grounding of the injection
molding machine should be performed separately, which can be stably operated without any
noise wave.
3.4.3 Precautions for the Static Noise Wave
The transportation equipments (specially, deliver the plastic inside its plastic tube by the air)
such as the plastic and molding product may generate an intense static noise wave. So, the
grounding joint of the equipment is practically performed.
The material transportation tube should be used the shortest limit length, and depart from
the controller and the screw position detection encoder as much as possible when the channel is
set. The molding product taken from the molds which do not pile nearby the operation panel,
because the strong static may cause the malfunction of the equipment, so it is necessary to
avoid it.

3.4.4 The Shield of the Electromagnetic Field Equipment
When the injection molding machine grounding connection is performed nearby the
equipment of the strong electromagnetic field, namely, the arc welding machine, discharging
processing machine, and the high frequency heater, the equipment with the noise wave should
be covered by the grounding metal shielding board.
3.4.5 The Use of the Internal DC Power
The AC power such as the DC24V, DC12V and DC5V inside the injection molding machine is
specially used for its internal system, not for the power of the external equipment. Do not use this
power on other purpose other than it is indicated in the User Manual. If you use it freely, it may
cause the low voltage or the noise wave may issue, and the malfunction or other stoppage of this
injection molding machine may generate.
3.4.6 The Usage of the Thermocouple
The thermocouple used in the injection molding machine and a microscale voltage value
may output based upon the temperature at the top of the temperature measure. This value is
formed a digital signal by the signal amplification and A/D conversion, so the voltage that gives
to the thermocouple circuit can not excessive, otherwise, the thermocouple amplification may be
damaged, and therefore, pay attention to the following proceedings when using.
(1) Pay attention to the leakage of the electric heater, which should be changed it
as for the one with poor insulation. Specially, the mold may be leaked using
the mini electric heater, so check the insulation resistance periodically.
(2) When the thermocouple top connected with the circuit should be disassembled
from the mold and heater hopper, do not put the static on the metal part of the
thermocouple. In this case, it is recommended that the top of the thermocouple
is temporarily connected with the metal parts such as the frame of the injection
molding machine.
