b) at a fixed or moveable control panel fixed to the machine the controls of which are not more than 1 800 mm above the floor level and the distance between its front face and the front edge of the infeed table shall be not more than 650 mm. The front face of the panel shall not protrude beyond the surface planing table at the operator position side.
Verthcatéon: By checking the relevant drawings, measurement and inspection of the machine.
5.2.3 StartIng
Before starting or restarting the machine all the interlocked safeguards shall be in place and functional. This is achieved by the interlocking arrangement described in 5.3.7. For non interlocked guards, guides adjustments provisions before starting see 6.3 j).
Start or restart shall only be possible by actuation of the start control device provided for that purpose. For electrically operated machines the requirements of 9.2.5.2 of EN 60204-1:2006 shall apply and In addition:
— for the purpose of this document “operation” means rotation of the cutterblock andlor powered adjustment:
— start of a demountable power feed unit — if fitted — shall be possible only where the tool spindle motor is running at full speed e.g. by using a time delay of fail safe technique e.g. of capacity type conforming to the requirements of category 3 according to EN ISO 13849-1:2006;
— design of the control circuits shall be such as to satisfy the starting sequence requirements. If a time delay device is used the time delay shall be at least equal to the run-up time, The time delay shall be fixed or the time delay device adjustment shall be sealed.
When the table(s) adjustment is powered, the control shall be of the hold to run control type. For machines with table(s) adjustment preset electronic control:
— either the table(s) adjustment speed shall not exceed 10 mm s1 and the start command may be category B according to EN ISO 13849-1:2006, or
— adjustment for the table(s) shall be initiated by a start command from the operator (e.g. push button) the control circuit of which conforms to category 1 or to category 3 in accordance with the requirements of EN
ISO 13849-1:2006.
At the end of programmed adjustment the power shall be cut to the adjustment actuator. A new initiation shall be necessary to perform additional adjustment.
The category of the control circuits (also see 5.2.1) for start and restart of the machine and for a demountable power feed unit (if fitted) shall be in accordance with the requirements of EN ISO 13849-1:2006 and at least:
For a category 1 normal stop control system, the stopping sequence shall be:
1) cut at the same time power to a socket for connection of a demountable power feed unit and to the cutterbiock motor and to the table adjustment if under preset electronic control, and apply the brake;
2) cut power to the brake after the tool has come to rest e.g. by a time delay of fail safe technique e.g. of capacity type or conforming to the requirements of category 3 according to EN ISO 13849-1:2006.
The design of the control circuits shall be such as to satisfy the normal stopping sequence requirements. If a time delay device is used the time delay shall be at least equal to the braking time. The time delay shall be fixed or the time delay adjustment device shall be sealed.
The category of the control circuits (also see 5.2.1)for normal stopping shall be in accordance with the requirements of EN ISO 13849-1:2006 and at least:
I) category 1 If the control circuits are hardwlred;
ii) category 3 if the control circuits include electronic components.
For machines designed to be used with de-mountable power feed unit or if a socket for a demountable power feed unit is fitted a separate category 1 stop control device in accordance with the requirements in 9.2.2 of EN 60204-1:2006 shall be provided for the de-mountable power feed unit only.
Verification: By checking the relevant drawings and/or circuit diagrams, inspection of the machine and relevant functional testing of the machine.
5.2.5 Emergency stop
Machines designed to be used with a demountable power feed unit or fitted with a socket for a demountable power feed unit or with preset electronic control for adjusting the height of the table(s) shall be fitted with an emergency stop control device which conforms to the requirements of 9.2.5.4.2 and 10.7 of EN 60204-1:2006. The emergency stop control device shall be at any time of self latching type.
In addition the following requirements shall be met:
If the machine is fitted with a mechanical brake the emergency stop function shall conform to category 0 in accordance with the requirements in 4.1.4 of EN ISO 13850:2006 and the emergency stop control circuit shall conform to category 0 in accordance with the requirements in 9.2.2 of EN 60204-1:2006 and shall fulfil the requirements of 9.2.5.4.2 of EN 60204-1:2006.
If the machine is fitted with an electrical brake the emergency stop function shall conform to category 1 in accordance with the requirements In 4.1.4 of EN ISO 13850:2006 and the emergency stop control circuit shall conform to category I in accordance with the requirements in 9.2.2 of EN 60204-1:2006 and shall fulfil the requirements of 9.2.5.4.2 of EN 60204-1:2006.BS EN 859-2007 pdf download.
