Unibor Airbor 2 - Manual (Page 3)

WARNING
• Non-compliance with any of these Special
Conditions could result in ignition of explosive
atmospheres.
• Rubbing and friction can cause sparks or
elevated temperatures that may be a source of
ignition of an explosive atmosphere.
Application & Installation
Bearing overload will cause premature bearing
malfunctions that may result in rubbing and
friction.
Comply with the following to prevent bearing
overload.
1 . Do not exceed factory recommendation for
maximum allowable shaft radial load versus
speed.
2. Refer to catalog data and/or an IR Technical
Specialist for specific technical information &
recommendations.
3. Driven loads should be balanced to eliminate
abnormal loading of the air motor bearings due
to radial vibration.
Ensure that motor shaft and driven rotating or
oscillating components do not come in contact
with other components.
1. Enclose or guard moving parts.
2. Mount air motor securely. A loose motor will
cause abnormal operation or may drop from
mounting.
3. Guard air motor from impact that may result in
a spark.
Motor Operation Conditions
Elevated surface temperature, an indication of
overload or potential failure of bearings or other
mechanical components, may create an ignition
source.
1 . The maximum expected surface temperature
(Tmax) of the entire machine, into which the
motor is incorporated, should be measured
and stated for the ATEX Directive Marking
Requirement and Certificate of Conformance.
2. Maximum bearing temperatures should not
exceed WC for an extended length of time.
3. Monitor air motor bearings and housing
temperatures during motor operation for
unusually high operating temperatures.
ROTARY AIR MOTORS
Special Conditions for incorporating into a machine for use in
Potentially Explosive Atmospheres
The EC Declaration of Incorporation in this manual states that these Air Motor model have been
reviewed as components for compliance with European Community Directive 94/9/EC for
equipment intended for use in potentially explosive atmospheres, commonly referred to as the
ATEX Directive.
These Air Motors were reviewed for conformance to ATEX designation:
ll 2 GD c llB 95 0 C X
These ATEX designations define the applications, the type and duration of the potentially explosive
atmospheres, the type of protection and the maximum surface temperature.
The ‘X’ indicates that additional special conditions are required for safe application, installation, operation
and/or maintenance when used in potentially explosive atmospheres.
The explosive hazard assessment of the complete machine into which this air motor will be incorporated will
determine the final ATEX marking and conditions. Because this air motor’s final machine incorporation is not
known, it has not been marked with the ATEX Directive symbols.
NOTICE
• All Special Conditions must be followed for this component to conform to
the ATEX Directive and for the ATEX Declaration of Incorporation to be valid.
