Programming Mode
– The robot is only to be programmed by the authorised personnel.
– Before starting to program, the operator must check the Robot System (Robot and
Control System) to make sure that there are no potentially hazardous irregular
conditions, and that there is nobody inside the protected area.
– When possible the programming should be controlled from outside the protected
area.
– Before operating inside the Protected Area, the operator must make sure from
outside that all the necessary protections and safety devices are present and in
working order, and especially that the hand-held programming unit functions
correctly (slow speed, emergency stop, enabling device, etc.).
– During the programming session, only the operator with the hand-held terminal is
allowed inside the
Protected Area.
– If the presence of a second operator in the working area is necessary when
checking the program, this person must have an enabling device interlocked with
the safety devices.
– Activation of the motors (Drive On) is always to be controlled from a position
outside the range of the robot, after checking that there is nobody in the area
involved. The Drive On operation is concluded when the relevant machine status
indication is shown.
– When programming, the operator is to keep at a distance from the robot to be able
to avoid any irregular machine movements, and in any case in a position to avoid
the risk of being trapped between the robot and structural parts (columns, barriers,
etc.), or between movable parts of the actual robot.
– When programming, the operator is to avoid remaining in a position where parts of
the robot, pulled by gravity, could execute downward movements, or move
upwards or sideways (when installed on a sloped plane).
– Testing a programmed cycle at working speed with the operator inside the
protected area, in some situations where a close visual check is necessary, is only
to be carried out after a complete test cycle at slow speed has been executed. The
test is to be controlled from a safe distance.
– Special attention is to be paid when programming using the hand-held terminal: in
this situation, although all the hardware and software safety devices are active, the
robot movement depends on the operator.
– During the first running of a new program, the robot may move along a path that is
not the one expected.
– The modification of program steps (such as moving by a step from one point to
another of the flow, wrong recording of a step, modification of the robot position out
of the path that links two steps of the program), could give rise to movements not
envisaged by the operator when testing the program.
– In both cases operate cautiously, always remaining out of the robot’s range of
action and test the cycle at slow speed.
