Environmental Considerations
placed on them. The
Moog Animatics Product Catalog
, contains information and equations that
can be used for selecting the appropriate motor for the application.
Replacement motors must have the same specifications and firmware version used in the
approved and validated system. Specification changes or firmware upgrades require the
approval of the system designer and may require another Risk Assessment.
Environmental Considerations
It is the responsibility of the machine/system designer to evaluate the intended operating
environment for dust, high-humidity or presence of water (for example, a food-processing
environment that requires water or steam wash down of equipment), corrosives or chemicals
that may come in contact with the machine, etc. Moog Animatics manufactures specialized IP-
rated motors for operating in extreme conditions. For details, see the
Moog Animatics Product
Catalog

Machine Safety
In order to protect personnel from any safety hazards in the machine or system, the
machine/system builder must perform a "Risk Assessment", which is often based on the ISO
13849 standard. The design/implementation of barriers, emergency stop (E-stop) mech-
anisms and other safeguards will be driven by the Risk Assessment and the safety standards
specified by the governing authority (for example, ISO, OSHA, UL, etc.) for the locale where
the machine is being installed and operated. The methodology and details of such an assess-
ment are beyond the scope of this manual. However, there are various sources of Risk Assess-
ment information available in print and on the internet.
NOTE:
The following list is an example of items that would be evaluated when per-
forming the Risk Assessment. Additional items may be required. The safeguards
must ensure the safety of all personnel who may come in contact with or be in the
vicinity of the machine.
In general, the machine/system safeguards must:
l
Provide a barrier to prevent unauthorized entry or access to the machine or system. The
barrier must be designed so that personnel cannot reach into any identified danger
zones.
l
Position the control panel so that it is outside the barrier area but located for an unres-
tricted view of the moving mechanism. The control panel must include an E-stop mech-
anism. Buttons that start the machine must be protected from accidental activation.
l
Provide E-stop mechanisms located at the control panel and at other points around the
perimeter of the barrier that will stop all machine movement when tripped.
l
Provide appropriate sensors and interlocks on gates or other points of entry into the pro-
tected zone that will stop all machine movement when tripped.
l
Ensure that if a portable control/programming device is supplied (for example, a hand-
held operator/programmer pendant), the device is equipped with an E-stop mechanism.
NOTE:
A portable operation/programming device requires
many
additional
system design considerations and safeguards beyond those listed in this sec-
tion. For details, see the safety standards specified by the governing author-
ity (for example, ISO, OSHA, UL, etc.) for the locale where the machine is
being installed and operated.
