Me6 & Me12 Controller User Manual

The purpose of this manual is to assist users in the integration, operation
and maintenance of the Me controller. This manual is designed to cover most
system congurations. If you need additional information specic to your
system please contact your representative or a Mold-Masters o󰀩ce whose
location can be found in the “Global Support” section.
1.1 Intended Use
The Me Series controller is an electrical distribution and control device
designed as a multi-channel temperature controller for use in hot runner
plastic molding equipment. It uses feedback from thermocouples within the
nozzles and manifolds to give precise closed-loop temperature control, and
it is designed to be safe during normal operation. Any other uses would fall
outside the engineered intent of this machine which may be a safety hazard
and would void any and all warranties.
This manual is written for use by skilled persons who are familiar with
injection molding machinery and their terminology. Operators should be
familiar with plastic injection molding machines and the controls of such
equipment. Maintenance persons should have su󰀩cient understanding of
electrical safety to appreciate the dangers of 3-phase supplies. They should
know how to take appropriate measures to avoid any danger from electrical
supplies.

Section 3 - Safety
3.1 Introduction
Please be aware that the safety information provided by Mold-Masters
does not absolve the integrator and employer from understanding and
following international and local standards for safety of machinery. It is the
responsibility of the end integrator to integrate the nal system, provide
necessary e-stop connections, safety interlocks and guarding, to choose the
appropriate electrical cable for the region of use and to ensure compliance
with all relevant standards.
It is the responsibility of the employer to:
• Properly train and instruct its personnel in the safe operation of
equipment, including the use of all the safety devices.
• Provide its personnel with all necessary protective clothing, including such
items as a face shield and heat resistant gloves.
• Ensure the original and continuing competence of personnel caring for,
setting up, inspecting and maintaining injection molding equipment.
• Establish and follow a program of periodic and regular inspections of
injection molding equipment to ensure it is in safe operating condition and
proper adjustment.
• Ensure that no modications, repairs or rebuild of portions are made
to the equipment that reduces the level of safety existing at time of
manufacture or remanufacture.

3.3 Operational Hazards
WARNINGS
• Refer to all machine manuals and local regulations and codes for safety
information.
• The equipment supplied is subjected to high injection pressures and high
temperatures. Ensure that extreme caution is observed in the operation
and maintenance of the injection molding machines.
• Only fully trained personnel should operate or maintain equipment.
• Do not operate the equipment with unconned long hair, loose clothing
or jewelry, including name badges, neckties, etc. These may get caught
in the equipment and can cause death or serious injury.
• Never disable or bypass a safety device.
• Ensure that the protective guards are placed around the nozzle to
prevent the material from splashing or drooling.
• A burn hazard exists from material during routine purging. Wear heat-
resistant personal protective equipment (PPE) to prevent burns from
contact with hot surfaces or splatter of hot material and gases.
• Material purged from machine may be extremely hot. Ensure protective
guards are in place around the nozzle to prevent material from
splashing. Use proper personal protective equipment.
• All operators should wear personal protective equipment, such as face
shields and use heat resistant gloves when working around the feed
inlet, purging the machine or cleaning the gates of the mold.
• Remove purged material from the machine immediately.
• Decomposing or burning material could result in noxious gases being
emitted from the purged material, feed inlet or mold.
• Ensure proper ventilation and exhaust systems are in place to help
prevent inhalation of harmful gases and vapors.
• Consult manufacturer’s Material Safety Data Sheets (MSDS).
• Hoses tted to the mold will contain high or low temperature uids or air
under high pressure. The operator must shut down and lockout these
systems as well as relieving any pressure before performing any work
with these hoses. Regularly inspect and replace all exible hoses and
restraints.
• Water and / or hydraulics on the mold may be in close proximity to
electrical connections and equipment. Water leakage may cause
an electrical short circuit. Hydraulic uid leakage may cause a re
hazard. Always keep water and / or hydraulic hoses and ttings in good
condition to avoid leaks.
• Never perform any work on the mold machine unless the hydraulic pump
has been stopped.
• Check frequently for possible oil leaks / water leaks. Stop the machine
and make repairs.

SAFETY
Me6 & Me12 Controller User Manual

WARNING
• Make sure that the cables are connected to the correct motors. Cables
and motors are clearly labeled. Reversing the cables can result in
unexpected and uncontrolled motion causing a safety risk or damage
to the machine. A crushing hazard exists between the nozzle and mold
melt inlet during carriage forward motion.
• A possible shearing hazard exists between the edge of the injection
guard and the injection housing during injection.
• The open feed port could present a hazard to a nger or a hand
inserted during operation of the machine.
• The electric servo motors could overheat presenting a hot surface which
could cause burns to someone touching it.
• The barrel, barrel head, nozzle, heater bands and mold components are
hot surfaces which could result in burns.
• Keep ammable liquids or dust away from the hot surfaces as they
could ignite.
• Follow good housekeeping procedures and keep oors clean to prevent
slips, trips and falls due to spilled material on the work oor.
• Apply engineering controls or hearing conservation programs as
necessary to control noise.
• When doing any work on the machine that requires moving and lifting
