6.1 Precautions before starting
The robot system (consisting of Robot and Control Unit) shall be operated in an
industrial environment by a qualified staff member that is acquainted with the
requirements related to the integration of a Robot in a complete machine, in compliance
with the basic safety prescriptions listed in the machine Directive.
For the sake of convenience, the qualified staff member that will carry out the activities
described here will be referred to as the “integrator”.
This chapter describes the minimum activities that the integrator shall perform to
upgrade the complete machine installing the Control Unit control devices and
emergency stop circuits.
Please remember that due to the Control Unit inherent features, a reduction of the
warranty cover may apply in case of multiple faults (see norm EN ISO 13849-1)..
6.2 Equipment and tools required
– Ordinary electromechanical equipment
– Clip for lugs.
– For X30 connector:
• Clip for Harting contacts, code 09.99.000.0001
• Puller for Harting contacts, code 09.99.000.0012
• Harting contacts, code 09.15.000.6203.
In order to comply with the norm requirements, the integrator is responsible for
the correct integration of the safety circuits in the robot system.
