ELECTRIC SHOCK HAZARD
Most controller warnings pertain to electrical hazards. It is crucial to comply
with these warnings to minimize any personal danger.
• Ensure that all energies are properly locked out in the controller and
mold machine before installation of the controller into the system.
• DO NOT enter the cabinet without rst ISOLATING the supplies.
There are unguarded terminals inside the cabinet which may have a
dangerous potential across them. Where a three-phase supply is used,
this potential may be up to 415VAC.
• Voltage and amperage cables are connected to the controller and the
mold. Electric power must be shut o󰀨 and lockout / tagout procedures
followed prior to installing or removing any cables.
• Integration should be done by properly trained personnel based on local
codes and regulations. Electrical products may not be grounded when
removed from the assembled or normal operating condition.
• Do not mix electrical power cables with thermocouple extension
cables. They are not designed to carry the power load or list accurate
temperature readings in each other’s application.
• The main power switch is found at the lower rear of the controller. It is
su󰀩ciently rated to handle the total load current during switch on and
switch o󰀨.
• The main power switch can be locked using a padlock applied under the
lockout / tagout procedure found in “Table 3-3 Energy Forms, Energy
Sources and General Lockout Guidelines” on page 3-11.
• Use lockout / tagout to prevent operation during maintenance.
• All maintenance should be performed by properly trained personnel
based on local laws and regulation. Electrical products may not be
grounded when removed from the assembled or normal operating
condition.
• Ensure proper grounding of all electrical components before performing
any maintenance to avoid potential risk of electrical shock.
3.9 MT/MT2 Controller User Hazards
WARNING
The display console and controller cabinet together are designed for use
in the plastic injection molding industry as temperature controllers for third
party hot runner systems as commonly used in mold tools. They must
not be used in residential, commercial or light-industrial environments.
Furthermore, they must not be used in an explosive atmosphere, or where
there is a possibility of such an atmosphere developing.
The controller cabinet and touchscreen console should be installed in a
clean dry environment where the ambient conditions do not exceed the
following limits:
• Temperature +5 to +45°C
• Relative Humidity 90% (non-condensing)
