MMD-TA-11B / MMD-TA-12B Muting Module
Instruction Manual
System Installation
3. System Installation
3.1 Appropriate Application
The correct application of the MMD-TA-11B and -12B Muting
Modules is dependent on the type of machine and the
safeguards that are to be interfaced with the Module. The
Module is generally interfaced with safeguards that may be
used only on machinery that is capable of stopping motion
immediately upon receiving a stop signal and at any point in its
machine cycle. It is the user’s responsibility to verify whether the
safeguarding is appropriate for the application and is installed as
instructed by the appropriate installation manuals.
Safety Light Screens, Single/Multiple Beam Safety Systems,
or other Presence-Sensing Safeguarding Devices (PSSDs)
generally may not be used for the following:
• With single stroke (also called “full revolution”) clutched
machinery, as this type of machinery is incapable of stopping
immediately.
• On certain other types of machinery, including any machine
with inadequate or inconsistent stopping response time, or any
machine that ejects materials or component parts through the
defined area.
• In any environment likely to adversely affect the efficiency of
the safeguard(s) or the Muting Module. For example, corrosive
chemicals or fluids or unusually severe levels of smoke or dust,
if not controlled, may degrade the efficiency of a safety light
screen.
If there is any doubt about whether or not your machinery is
compatible with this Muting Module, contact Banner’s Application
Engineers at the factory.
WARNING . . . Stand-Alone Point-of-
Operation Guarding
The Muting Module is not a stand-alone point-
of-operation guarding device, as defined by
OSHA regulations. It is necessary to install point-of-operation
guarding devices, such as safety light screens and/or hard
guards, to protect personnel from hazardous machinery.
Failure to properly install point-of-operation safeguarding
on hazardous machinery, as instructed by the appropriate
installation manuals, can result in a dangerous condition
which could lead to serious injury or death.
WARNING . . . Read this Section
Carefully Before Installing the System
The Banner MMD-TA-11B or -12B Muting
Module is an accessory device that is typically used in
conjunction with a machine safeguarding device. Its ability to
perform this function depends upon the appropriateness
of the application and upon the Muting Module’s proper
mechanical and electrical installation and interfacing to
the machine to be guarded.
If all mounting, installation, interfacing, and checkout
procedures are not followed properly, the Muting Module
cannot provide the protection for which it was designed.
The user has the responsibility to ensure that all local, state,
and national laws, rules, codes, or regulations relating to the
installation and use of this control system in any particular
application are satisfied. Extreme care should be taken to
ensure that all legal requirements have been met and that all
technical installation and maintenance instructions contained
in this manual are followed. Read Section 3 (and its
subsections) of this manual carefully before installing the
system. Failure to follow these instructions could result in
serious bodily injury or death.
The user has the sole responsibility to ensure that this Muting
Module is installed and interfaced to the guarded machine by
Qualified Persons (see Section 1.18), in accordance with this
manual and applicable safety regulations.
WARNING . . . User Is Responsible
for Safe Application of this Product
The muting application examples described in
Appendix B depict generalized guarding situations. Every
guarding application has a unique set of requirements.
Extreme care is urged to ensure that all legal
requirements are met and that all installation instructions
are followed. In addition, any questions regarding
safeguarding should be directed to the factory
applications department at the number or addresses listed
on the front cover.
