6 5 Safety requirements and/or measures Replace entire clause 5.5 by the following 5.5 Manually-fed stand-alone platen presses, for single stroke mode, dwell mode and continous operation mode for cutting and creasing Safeguarding shall be provided in those areas where it is recognized that operators are exposed to significant hazards. The guarding requirements of EN apply. Guard construction shall meet the requirements of EN 953. All platen presses shall have trip bar(s) (see 5.5.3) or other protective devices (see 5.5.4) located where access to a hazard is possible General safeguarding requirements On machines wider than 1.6 m the impact hazard created by the movable platen while opening shall be guarded by the use of a knee bar (See Figure 21, Item 7).The length of the knee bar shall be equal to or greater than the width of the movable platen. The knee bar shall be constructed such that it will retain its shape to ensure actuation of the trip function throughout its length. With the movable platen in the open position, the clearance between the knee bar and front surface of the movable platen shall be at least 120 mm (see figure 21). All mechanical trip bars shall be provided with a switch mounted on each end of the trip bar. The signals of the switches allocated to the individual trip device shall be processed separately. The conductor cables connecting the switches shall be physically separated and shall be located outside the electrical cabinet. Pressure sensitive protective devices shall satisfy the requirements of EN Trip functions using mechanical devices (including knee bars) shall satisfy the requirements of ISO and PL r e of ISO or SIL3 of IEC Trip functions or presence sensing functions using laser scanners shall satisfy the requirements of PL r d of ISO or SIL2 of IEC The safety system that controls trip devices and their related signal processing, which safeguard routine and regular access to a hazard point on a manually-fed machine, shall comply with PL r e of ISO or SIL3 of IEC Safeguarding side access Various means may be used to prevent access from the sides of the press. Those means include, but are not limited to, the following measures: a) Fixed protective barriers, interlocking guards and/or interlocking tables that prevent access, from any side of the press according to tables 2 and 4 of ISO Tables shall extend 1000mm from the side frame outward and over the length of the press, reaching from the front edge of the open position of the moveable platen to at least 250 mm behind the backward edge of the trip device. See figure 21 and 24. b) Laser scanners meeting the requirements of 4.3. provided on both sides of the platen with the scanned area being at a distance of 200 mm minimum and 250 mm maximum (measured from the beginning of the scanned area). The size and shape of the scanned areas on the sides shall be as shown in Figure 25a. Access between the laser scanners and the machine housing from the front and rear of the platen press to the danger zones shall be prevented by fixed guards (see Figure 25b). 6

7 Means of preventing access to the dangerous zone between the movable platen and punching plane other than those defined at a) and b) shall provide an equivalent level of protection Additional requirements for manually-fed platen presses in dwell or continuous operation mode One of the following configurations shall be provided: a) An interlocked protective device (U-shaped trip bar) that covers both the sides and the top of the point of operation shall be provided, (see Figure 21 and Figure 22). The platen trip bar shall pass under the U- shaped trip bar in its operating position with a clearance of 12 mm maximum (see Figure 23). The minimum distance shall be maintained throughout the range of all operating temperatures. If the stopping distance specified by the manufacturer is exceeded, the control system shall prevent an additional cycle until the brake/clutch system is adjusted. This requirement shall be met at all speeds of the machine. The stopping distance shall be monitored at the end of each cycle. NOTE A cycle begins in the stopped position and is completed when the platen returns to the stopped position. The U-shaped trip bar pivot shall be rated such that a force of 20 N is sufficient for actuation and triggering of the clutch/brake device. The pivot of the U-shaped trip bar shall be below the punching plane (see Figure 24). For manually-fed machines operated in the automatic (timer-controlled) mode an additional trip bar, usually located on the top edge of the movable platen, shall also be provided. This trip bar, when actuated, stops platen motion. For machines greater than 1 m wide, a presence-sensing device that will detect the presence of a person on the moveable platen shall be provided. If a person is detected, start-up shall be prevented. b) Laser scanner in accordance with Dimensions in millimetres Key 1 trip bar on movable platen 5 front edge of interlocking table 2 U-shaped trip bar on fixed platen 6 interlocking table 3 punching plane 7 knee bar 4 lower edge of punching plane Figure 21 Interlocking tables 7

For the presence-detection of person at presses with a platen wider than 1m, a laser scanner mounted on the top of the fixed platen (see scanned area on the top (3) in Figure 25) shall be provided. The gap between the scanned area and the movable platen in fully open position shall be a maximum of 350 mm. When the press is in motion and the presence of a person is detected, the machine shall stop with a stopping distance, measured at the top of the platen, not exceeding 120 mm. The further movement of the platen shall require a reset and not automatically restart. When the platen press is stopped, and the presence of the person is detected by the laser scanner, an unexpected start-up shall be prevented and the press shall not automatically start. Laser scanners shall meet the requirements of IEC and IEC Dimension in millimetres 9

The warning requirements of shall be met. 10

11 5.5.6 Stopping distance The stopping distance of the platen press shall not exceed 120 mm. This shall be measured between the top edges of the moveable and fixed platens. On manually-fed platen presses, if the stopping time or stopping distance specified by the manufacturer to meet the requirement of the previous paragraph is exceeded, start-up shall be prevented. The stopping distance shall be monitored at the end of each cycle Main drive braking and clutch/brake mechanism Manually-fed platen presses shall be equipped with a fail-safe clutch/brake mechanism to disconnect the stored energy in the flywheel from the moving platen and bring the platen to a stop thereby preventing press motion. On presses with flywheels, this mechanism shall be located on the fly-wheel shaft. When using a clutch/brake mechanism, electric power supply failure, or loss of pneumatic or hydraulic pressure, shall activate the brake and disengage the clutch (i.e. fail-safe). The brake shall be of sufficient strength to maintain the platen in the position in which it stopped due to the failure. If a pneumatic system is used for the combined clutch and brake system (stopping closing movement of the platen) two pneumatic valves shall be provided. The pneumatic system shall meet PL r e of ISO The pneumatic system shall comply with the requirements of EN Flywheels Flywheels shall be enclosed or otherwise guarded in accordance with EN A flywheel retention device shall be provided to ensure that the flywheel will not come off its shaft unexpectedly. NOTE A key in a keyway is not considered to be a flywheel retention device Controls Pushbuttons General Pushbuttons shall meet the requirements of EN and Emergency stop On manually-fed platen presses, an emergency stop pushbutton shall be provided on the motion control station. The emergency stop control shall meet the requirements of EN Other controls Control to permit manual movement of machine A control shall be provided to release the brake and engage the clutch, if necessary, to permit manual movement of the press. This control shall only function when the motion of the main drive motor is inhibited Selector switches Multiple-position selector switches may be used in conjunction with another motion control, and shall not be an alternative or substitute for the pushbutton controls defined in EN

12 Automatic stop After an automatically-initiated stop, the press shall not automatically start. The operator shall go through the normal starting sequence, in order to initiate press motion. NOTE An automatically-initiated stop may be the result of the activation of a guard interlock, stop after the scanner detects an obstruction Signals and warning devices Indicator light for automatic mode A flashing red indicator light shall be provided in the operator's view clearly indicating when the machine is in dwell mode. 6 Verification of safety requirements and/or measures Replace in clause 5 "Table 2" with "Table 3". Replace in table 3 "Hand-fed platen machines" with "manually-fed platen presses" 7 Instruction for use Replace the entire clause by the following Manually-fed platen machines The instruction handbook shall state: that safety devices (e.g. trip bars and laser scanners) and brake shall be checked daily for proper operation, removable safety test trip with the press set at its maximum operating speed; that test results of the daily testing of the safety devices should be recorded; that checking shall be carried out when the operating temperature of the machine is reached; that where the function of the devices is inappropriate, the machine shall be closed down until defects have been eliminated; procedures for safe routine adjustment, cleaning, inspection and maintenance of equipment, including power isolation procedures). 12
