2.1
Methods of Protection

1, Groups A, B, C and D indoor hazardous (classified), and appear in the Factory Mutual (FM)
Research Approval Guide.They have the construction of protection as follows:
Metod of Protection;
• The pressurized explosion-proof method prevents explosive gas from entering the
manipulator by supplying a protective gas, such as clean air or an inert gas, to keep the
internal air pressure constant.
• The Intrinsic-safety explosion-proof method prevents explosive gas from igniting by
electric spark and heat.
2.2
Teaching
The target positions, the motion speed, and the ON/OFF timing of the spray can be taught
with the programming pendant while moving the manipulator, which shortens the time
required for teaching. And, the data can be corrected at any time.
Because the teaching function and the correction function are integrated, the operations such
as forward/reverse run, position modification, addition/deletion of points can be performed
during teaching. And the management function, which manages the parameter settings,
enables you to monitor the actual status during teaching. The on-screen guidance and the
interactive system on the pull-down menus lead the operator through the operation proce-
dures.
(1) Large-capacity backup as a standard feature
The large-capacity drive for PC cards is provided as a standard feature of backup
unit and enables data to be transmitted easily.
