EN 1218-3:2001 (E)
It shall be possible to start each sawblade drive motor separately.
Verification : By checking the relevant drawings and/or circuit diagrams, inspection and relevant functional testing
on the machine.
5.1.4 Normal stopping
A stop control shall be fitted which, when actuated, stops all machine actuators and cuts power to them once
stopping is complete.
The category of the stop function (category 0 or 1) shall be in accordance with the requirements of 9.2.2 of EN
60204-1: 1992, where the "safety and/or functional“ requirements of the machine are fulfilled by maintaining power
to the electrical brake (if provided) and/or powered clamping (if provided) until stopping is complete.
These requirements shall be satisfied at the level of the control circuits. If a time delay device is used, the time
delay shall be at least the maximum run-down time. Either the time delay shall be fixed or the time delay
adjustment device shall be sealed.
If the emergency stop provided by virtue of 5.1.5 also achieves at least the above requirements, then the
emergency stop can be regarded as fulfilling the requirements of the normal stop control.
Verification : By checking the relevant drawings and/or circuit diagrams, inspection and relevant functional testing
on the machine.
5.1.5 Emergency stop
See EN 418 : 1992 and in addition :
Machines shall be fitted with an emergency stop control(s) which shall conform to the requirements of 9.2.5.4 and
10.7 of EN 60204-1: 1992. However 10.7.5 of EN 60204-1: 1992 does not apply.
