139 Replace the existing subclause 22.104 with the following:
140 “22.104 Working area
141 When the machine is operating in automatic mode, the machine shall not be able to leave the working
142 area. It shall not be possible for the machine to cross the boundary of the working area by a distance
143 greater than one full length of the machine when operating in automatic mode.
144 The boundary of the working area may be established by the use of a perimeter delimiter as specified
145 in 22.104.2 or by a pre-programmed area.
146 If the machine is placed outside the working area, it shall not be able to operate at a distance of more
147 than 1 m from the boundary of the working area to the nearest part of the machine, unless under manual
148 control.
149 If the machine fails to receive any signal that is required to recognize the working area, the machine
150 shall travel not more than 1 m or travel such that it is not displaced by more than 1 m and the cutting
151 means shall stop within 5 s from the instant the machine fails to receive any signal that is required to
152 recognize the working area to the time that the cutting means stops in accordance with 20.102.2.
153 If the machine regains recognition of the working area, the machine may operate in automatic mode,
154 providing the cutting means start-up indication procedure in 22.110 is completed.
155 If the working area is changed, it shall not be possible for the machine to operate in automatic mode
156 unless the restart procedure in 20.102.6 is completed. This requirement is not applicable for perimeter
157 delimiters.
158 Compliance is checked by inspection, by measurement and by practical test.
159 If the compliance relies on the operation of an electronic circuit, it is checked under the following
160 condition:
161 1) the fault conditions in a) to g) of 19.11.2 applied one at a time to the electronic circuit.
162 The total travelling distance and/or the total stopping time, as a result of condition 1), shall not exceed
163 twice of the values given above. Under this condition, a manual operation shall be required to restart
164 the cutting means, such a restart shall only be allowed for one attempt.
165 If the electronic circuit is programmable, the software shall contain measures to control the fault/error
166 conditions specified in Table R.1 and is evaluated in accordance with the relevant requirements of
167 Annex R.
168 22.104.1 Void
169 22.104.2 Perimeter delimiter
170 If a perimeter delimiter is provided which uses a boundary wire that emits a signal to indicate the limit
171 of the working area, the maximum voltage shall not exceed safety extra-low voltage.
172 Compliance is checked by measurement.”
173 Replace the existing subclause 22.105.2 with the following:
174 “22.105.2 Obstruction sensors
175 The machine shall be provided with (an) obstruction sensor(s). In automatic mode, the sensor(s)
176 shall be active and capable of performing its intended function in all operating positions and in all
177 directions of travel, except those directions of travel where
178 — the cutting means is not operating and the distance travelled does not exceed 2,0 times the length
179 of the machine; or
180 — the cutting means is operating and the distance travelled does not exceed the distance from the
181 edge of the machine in the direction of travel to the nearest cutting means tip circle.
182 NOTE 1 The machine does not have to incorporate discrete sensing devices for each sensor requirement. The
183 various sensing functions can be achieved by fewer devices that respond to multiple stimuli. Sensing requirements
184 can also be fulfilled by mechanical devices instead of electrical circuits.
185 The maximum kinetic energy of a machine that could be imparted to an obstruction upon impact when
186 travelling in automatic mode shall be 5 J.
187 The maximum force applied by the machine against an obstruction in automatic mode shall not be
188 greater than
189 — 260 N during the first 0,5 s after impact and a minimum of 50 N is exceeded; and
190 — 130 N thereafter.
191 NOTE 2 ISO/TS 15066:2016 provides guidance on relevant values of maximum force.
192 If an obstruction sensor is activated, the traction drive in the direction of travel shall stop within
193 t = D/v, where
ts
t is the traction drive stopping time;
ts
D is the distance from the front edge of the machine to the nearest edge of the nearest
cutting means tip circle; and
v is the velocity of the machine upon approach.
194 The machine shall then restart in a different direction to allow the machine to move away from the object
195 such that the sensor is deactivated within 3 s of initial activation. If the sensor is not deactivated within
196 3 s of initial activation, the cutting means shall stop as required by 20.102.2.
197 An additional non-contact sensor, if relied upon to reduce speed in order to fulfil the requirement for
198 maximum force upon impact, is permitted providing that it responds to a rigid non-metallic target of:
199 — cylindrical shape;
200 — (70 ± 2) mm diameter by (400 ± 5) mm high, standing on end;
201 — of a colour or shade that matches the background; and
202 — normalized to the ambient temperature.
203 Compliance is checked by inspection, by measurement, by the following test and by 20.102.2.
204 The machine is placed on a level test surface as described in CC.3. The machine shall be made to
205 collide with a force measuring means. The force to operate the obstruction sensor at impact shall be
206 measured parallel to the ground plane and vertically aligned with the point of contact with the force
