4.3 Automatic Operation
4.3.1 The robot system can only be activated for automatic operation by authorised personnel when the
protective barriers are closed and electrically interlocked as specified in the safety standards.
4.3.2 Prior to activating automatic operation, the operator must check the robot system and the pro
-
tected area to make sure there are no potentially dangerous anomalous conditions.
4.3.3 The operator can only activate automatic operation after checking that:
·
the robot system is not being maintenanced or repaired;
·
the protective barriers have been positioned correctly;
·
there is noone inside the protected area;
·
the control unit doors are locked by properly key.
·
the safety devices (emergency stop, protective barrier safety devices) are working properly;
·
the portable programming terminal has been placed in its housing (this condition is requested
by the controller in Auto-Remote status).
4.3.4 Special attention must be paid when selecting the automatic- remote status, in which the line PLC
may automatically switch on the motors and start the program.
4.4 Emergency Manual Operation
(In case the manual emergency operation state is provided for)
4.4.1 Emergency Manual Operation can be activated by authorized personnel only.
4.4.2 This operating mode must only be used when special robot system conditions will not allow the
use of manual movement during programming.
4.4.3 Emergency manual operation must be controlled from outside the protected area since the safety
system is downgraded.
4.4.4 If it is absolutely necessary to work inside the protected area, The robot system integrator must
realize an appropriate safety circuit that allows the operator to move the robot with the safety bar
-
riers deactivated.
In that case, before performing manual emergency operations, the operator must check, while re
-
maining outside the protected area, the correct functioning of the safety devices that are active in
this state and the teach pendant utilized as a portable emergency pushbutton panel..
4.4.5 Take great care during emergency manual operation remaining outside the work envelope of the
robot and its fixtures and pay particular attention to the axes that may drop due to the force of
gravity.
4.4.6 Braking release device of robot axes. With the driving force excluded, the robot can be moved
by the manual brake release device, directly connected to the robot or installed on it, which only
permits the deactivation of the brake of each axis individually .In this situation all the system
safety devices (including the emergency stop and enable buttons) are excluded. Any axes to be
handled (that could drop due to the force of gravity) should be put in slings.
