Rail dependent storage and retrieval equipment - Safety requirements

This standard applies to all types of S/R machines, restricted to the rails on which they travel within and outside the aisles, which embody lifting means and may embody lateral handling facilities, for the storage and retrieval of unit loads and/or long goods such as bar materials and/or for order picking or similar duties. Also included is the transfer equipment used to change between aisles. Control of machines may range from manual to fully automatic.
This standard does not apply to free ranging industrial trucks or robots.
References in this standard to racking, buildings and systems only apply where it is necessary to assess the hazards and risks at their interfaces with S/R machines.
This standard deals with all significant hazards relevant to rail dependent storage and retrieval equipment, when they are used as intended under the conditions foreseen by the manufacturer (see Clause 4).
This standard applies to machines and equipment that are manufactured after the date of issue of this standard.
Illustrations of examples of machines and transfer equipment to which this standard applies are shown in Annex A.
   Safety requirements and/or measures in this standard apply to equipment used under indoor conditions. However, additional risk assessments and safety measures need to be considered for uses in severe conditions, e.g. freezer applications, high temperatures, loads, the nature of which could lead to a dangerous situation (e.g. especially brittle loads, explosives), earthquake effects and also contact with foodstuff. Hazards during decommissioning are not covered.
   This European Standard deals as well with the technical requirements for electromagnetic compatibility (EMC).
Noise emitted by these machines is not considered as significant but as a relevant hazard. This means that the manufacturer of the machine is obliged to carry out noise reduction and indicate the noise level.

5 Safety requirements and/or protective measures for all types of S/R machines
5.1 Introduction
Machinery shall comply with the safety requirements and/or protective measures of this clause, Clause 6,
Clause 7 and Clause 8. In addition, the machine shall be designed according to the principles of
EN ISO 12100 (all parts) for relevant but not significant hazards, which are not dealt with by this standard.
Controls and other electrical components shall be in accordance with EN ISO 13849-1, EN ISO 13850 and
EN 60204-32 apart from the deviations stated in the following clauses.
Machines and sub-assemblies shall be provided with lifting points unless these are not required by design.
5.2 Control position
S/R machines with one or more on-board operators shall have an onboard control position. This may be
mounted on the lifting carriage, move independently of the lifting carriage, or may be mounted in a fixed
position on the machine.
In the case of fully automatically controlled machines an onboard control position may be dispensed with, but
an emergency control position shall be provided for each machine.
5.3 Control equipment
5.3.1 General
The text of 5.3 and its sub-clauses fully replaces and deviates from the text of 9.4 in EN 60204-32:1998 and
its subclauses.
Safety related parts and safety related functions are listed in Table C.1 and Table C.2 respective of Annex C.
Performance levels shall be in accordance with the performance levels required in these tables.
Adjustable safety related parts (e. g. electronic control circuitry, software, safety devices) shall be protected
against access by unauthorised persons (e. g. by the use of access codes, seals, enclosures, tools).
Safety related parts shall be designed, located or protected to withstand foreseeable strain or damage.
The switching contacts of mechanically actuated electrical safety devices shall be the positive opening type as
defined in Clause 3 of EN 60947-5-1:2004. (i.e. “safety switches”).
5.3.2 Prevention of unauthorised operation (equipment switch)
A key operated switch shall be fitted to the control panel of each machine to prevent unauthorised operation.
With the key switch in the "off" position, all movements of the machine shall be prevented (see 5.3.3). It shall
only be possible to remove the key from this switch in the "off" position.
For manual machines this key allows the operator to take control of the machine. In the case of automatic
machines this key, in conjunction with the key in 5.3.3, allow operation of the machine for commissioning, fault
finding or any other work where the machine needs to be operated by manual control.
5.3.3 Changing mode of operation (mode switch)
To prevent danger due to a change from manual to automatic control, or vice versa, one or more key operated
mode switches, or alternative means providing the same level of safety, shall be provided for each automated
machine (see 6.3.1 and 7.3.1). The mode switches are associated with the safety concept of limited access
described in 5.10.3.1 (see also Figure A.3 in Annex A). When a mode switch is actuated, powered motion
shall cease. The machinery shall then remain in a stationary condition. Separate start devices at the external
control position, located if possible in the direct sight of the machine and on the machine (emergency control
position or onboard control position), shall be provided to be actuated and thus restart the machine.
It shall only be possible to remove the key from the mode switch on the machine in the "automatic" position
and from the mode switch at a control position outside the machine operating area in the "manual" or "off"
position.
5.3.4 Key dependence
For manual machines the door key (see 5.10.3.2.b)) shall be the same key as specified in 5.3.2, or
permanently attached to it. For automatic machines the door key shall be the same key as specified in 5.3.3,
or permanently attached to it. Equivalent key dependent systems, e. g. key transfer systems as described in
Annex E of EN 1088:1995, may be used.
Where one machine is dedicated to one enclosed aisle, then each key shall be unique to a machine and the
access door associated with the machine operating area.
Where machines are not dedicated to one aisle (e. g. machines with transfer devices, curve going machines)
the key shall be unique for each dedicated aisle entrance door. The key for the machines may all be the same
but permanently attached to the entrance door key.
5.3.5 Control devices for powered movements
Control devices for all movements shall be designed and arranged so that they may be actuated easily and
safely and so that the possibility of unintended actuation is avoided.
For machines with fully enclosed on-board control position (see 6.3.2) the stop category may be 2 (see
5.3.7.1). If a stop command is given, powered motion shall cease and the equipment shall then remain in a
stationary condition until the start control device has subsequently been actuated.
5.3.6 Control device identification
Each control device shall be identifiable and clearly marked with the resultant direction of movement in the
language of the country of use or by pictograms where appropriate. The way in which the control devices are
actuated shall, as far as possible, correspond to the particular movement.
NOTE The application of EN 61310-3 is recommended.
5.3.7 Stop function
5.3.7.1 Stop categories
The stop function shall comply with 9.2.5.3 of EN 60204-32:1998 and 5.2 of EN ISO 13849-1:2008 and shall
be:
 category "0" or "1" stop, or
 category "2" stop,
as required by the design (see 9.2.2 of EN 60204-32:1998).
5.3.7.2 Initiation of the stop-function
After a stop function has been initiated powered motion shall cease. If a stop control does not cut off the
energy supply (category "2" stop) the stop condition shall be monitored and maintained. The equipment shall
then remain in a stationary condition until a start device has subsequently been actuated.
5.3.8 Emergency stop function
5.3.8.1 General
The emergency stop function shall comply with EN ISO 13850:2008, 5.3 of EN ISO 13849-1:2008 and shall
be provided to stop the machine without creating additional risks. The stop category 0 or 1 shall be chosen
according to the design of the drives.
NOTE Stop category 1 may be used for machines with electronically controlled drives (this deviates from 9.2.5.4.2 of
EN 60204-32:1998).
5.3.8.2 Location of actuators
In addition to the requirements of 10.7.1.1 of EN 60204-32:1998 the actuators for the emergency stop function
shall be located in all control positions as a minimum.

NOTE The provision of actuators for emergency stop function should be considered for other working positions, e. g.
hoist platforms, maintenance platforms, etc.
If an emergency stop device is actuated, the emergency stop function shall be initiated automatically and
powered motion shall cease. The equipment shall then remain in a stationary condition until the emergency
stop device has been reset and the start device has subsequently been actuated.
5.3.8.3 Electronic devices
Programmable electronic equipment or electronic devices (including electronic sub-assemblies) may be used
for emergency stop functions if the devices and equipment are at least in accordance with the requirements of
Annex C.
NOTE This is not in accordance with 11.3.4 of EN 60204-32:1998.
5.3.9 Safety requirements related to EMC
NOTE This clause is related to the Machinery Directive.
The machine shall have sufficient immunity to electromagnetic disturbances enabling it to operate as safely as
intended and shall not fail to danger, when exposed to the levels and types of disturbance as specified in
EN 61000-6-2. The manufacturer of the machine shall design, install and wire the equipment and sub-
assemblies, taking into account the recommendations of the supplier(s) of the sub-assemblies, to ensure that
the effects of electromagnetic disturbances generated shall not lead to unsafe operation and/or failure to
danger.
There shall be no loss of performance or degradation of performance that could lead to danger. In particular,
the following losses of perfor
