Note: in this case the MTTFD = MTTF because DC=0 (no monitoring of the dangerous faults). For IEC 62061: 2005 MTTF min = tbd Note: in this case the MTTFD = MTTF because DC=0 (no monitoring of the dangerous faults). Note: The faults monitoring can be carried out by disconnecting the voltage supply to the emitter or by switching off the beam(s) of the emitter. Note for the WG: Verify with the experts of IEC62061 and ISO 13849-1 the values of the MTTFD (low, medium, high) and the values of �.Type 2 II - One or more separate single beams tested individually.

A.7.1.4� There shall be at least two independent hard-wired muting signal sources to stop the function. The muting function shall stop when the first of these muting signals changes state. The deactivation of the muting function shall not rely only on the clearance of the ESPE. NOTE� In some applications, the signal sources for initiating and stopping the mute function may be the same. The muting sensors are included in the safety performance calculations as part of the safety function. Note to WG – Applications requiring muting for a long period of time (hours or days) should be addressed further in TS62046.

Enhanced Annex E draft (informative)

Explanation of Emergency Operation E.1 General Emergency operation includes separately or in conjunction; Emergency stop: An emergency operation intended to stop a process or a movement that has become

hazardous. Emergency switching off: An emergency operation intended to switch off the supply of electrical energy

to all or a part of an installation where a risk of electric shock or another risk of electrical origin is involved.

Emergency start: An emergency operation intended to start a process or a movement to remove or to avoid a hazardous situation.

Emergency switching on: An emergency operation intended to switch on the supply of electrical energy to a part of an installation that is intended to be used for emergency situations.

This standard specifies the requirements for emergency stop and emergency switching off. Annex E gives

explanation to help understand these requierments.

The purposes of emergency stop and emegency switching off are different. But they have a common

feature. They are in common that each of these emergency operations disconnects the electrical power

wholy or partly from the electrical equipment of a machine. The disconnection often results in the same

consequence. For example, emergency stop can reduce the harm of electric shock and emergency

swtcinig off can stop the hazardous movement of moving part. A disconnecting device having breaking

capacity can serve as an emergency stop device and an emergency switching off device.

Emergency stop system and emergency swtching off system are not to be used frequently. They may be

considered as a safety-related control function with low demand of operation. But when actuated for

emergency purposes they must operate correctly. It is recommended to test the correct operation of these

emergency functions periodically to reduce the risk of failure of correct functioning in emergency.

E.2 Emergency stop E.2.1 Significance of emergency stop function Emergency stop function is not an inherently safe design maeasure to eliminate hazards that can appear

during operation of machines. It is not a kind of protective equipment to prevent persons from approaching

machines. Emergency stop is a function to minimize the harm when someone becomes aware of

emergence of hazardous situation with the machine.

Hazrdous situations where an emerency stop function is expected to reduce the harm include ;

- the machine comes out of control,

- a person approachs or be entangled in the moving part of the machine,

- a work in process is unfastened, entangled, or damaged.

Emergency stop

Emergency switching off

Fig E.0 – Overlap of the effect of emergency stop and emergency switching off

－150－

It is unlikely that a workplace or a machine is entirely free of emergence of a hazardous situation where a

person can be injured or a workpiece can be damaged. In spite of the full impulmentation of 3 step safety

measures (inherently safe design measure, safeguarding and protective equipment, information for safe

use) an unexpected hazardouse situation can happen.

Unexpected hazardous situations or events include;

- miss operation of the operator,

- failure of machine control function,

- failure of protective equipment,

- circumvention of protective equipment,

- breakage of workpiece in process.

It is generally considered that emergency stop function is required for many kinds of machine to cope with

these enexpected hazardous situations.

Emergency stop function is not to be used frequently. But when it is used it is ofeten the case that a

human life depends on the correct functionig of the emergency stop function. Therefore, the probability

that the emergency stop function fails at the time of emergency operation must be minimized. Situations

where emergency stop function does not work correctly include;

- emegency stop function is in failure due to, for examples;

- emergency stop actuator is in failure,

- wireing in emergency stop circuit is discontinued or short-cicuited,

- the control circuit between emergency stiop actuator and the power contactor is in failure,

- power source for emergency control circuit is in failure or not supplied,

- the power contactor deoes not open its contacts due to contact adhesion.

- emergency stop actuators on the control station (panel) or at the necessary location can be in

inefective condition due to, for exampls;,

- the removable controller at hand is disconnected.

- where multiple controllers and multiple machines are employed the specific controller at hand is

not asigned for the intended machine.

- where multiple controllers are assigned for single machine the specific controller at hand is in

disable condition.

- the cableless controller at hand is in such a condition as;

- the power is not supplied.

- the wireless communication link is not established.

- the controller is not assigned to be valid (address code is wrong).

When the emergency stop function is in ineffective condition it is recommended that the start of the

machine operation is impossible or such an emergency stop actuator cannot be accessible or

missunderstabdable to be effective. To avoid the possibility that an ineffective emergency stop actuator is

accessed in emergency situation it is reccommended that whether or not the actuator is in effective

condition is evident, especially in such cases as;

- multiple emergency stop actuators are provided within a short distance,

- the emergency stop actuator is mounted on a removable controller,

- the emergency stop actuator is mounted on a cableless controller.

－151－

Additional hazards must not be created by an emergency stop operation. Additional hazards to be

prevented in emergency stop operation includes;

- ejection of wrorkpiece (at proces machine)

- fall of suspended load (at whisting machene)

Possibility of inadvertent and mischievas operations of emergency stop actuator must be minimized.

Emergency stop operation must be possible only at the place where one can observe the intended

machine. In case of a portable or cableless controller this is especially importanet.

E.2.2 Comparison of emegency stop function with other stop functions Table E.1 gives the comparison of emergency stop, normal stop and automatic interlock stop.

E.2.4 Examles of emergency stop systemThis subclause gives four examples of emergency stop sytem from simple to complex.

Example1 Direct emergency stop system (Fig E.1) (without control wire, stop category 0) The main disconnecting device serves as the emergency stop device. The handle of the disonnector is the

emergency stop actuator. The colour of the handle is red. The immedeate background of the handle is

yellow.

This is the most primitive but the most secure emergency stop system. When the handle and the electrical

power contacts of the disconnector are positively linked the stop is assured. It is required that the

disconnector has the necessarry breaking capacity.

This system gives catogory 0 stop. The moving part with inertia may not stop at once unless mechanical

break is used.

Reclousure of the disconnector must not restart the machine. Restart of the machine must require the

operation of the start control button after th reclosure of the disconnector. Provision of separete E stop

reset button may prevent unexpected restart of machine.

Example 2 Hard wired emergency stop system (Fig.E.2) (stop category 0) This emergency stop system comprises; • emergency stop actuator (on the control panel) • control wire • power contactor

The emergency stop actuator has direct opening contacts in accordance with IEC 60947-5-5. The actuator is a push-button of mushroom type or palm type with red color and the background is yellow On actuation of the emergency stop actuator the contactor is directly de-energized and opens its power contacts resulting in the stop of the machine.

The prevention of the contact adhesion of the contactor is very important. If the power contacts of the contactor are in adhesion the intended emergency stop may not be achieved. There are many examples that two power contactors are connected in series to reduce the risk that the stop function fails due to the contact adhesion of one contactor.

It is possible to duplicate the emergency stop function by, for example, making the main disconnector to effect emergency stop as in Example 1.

3 Proposal to change the title of IEC 62046 The current title “Safety of machinery – Application of protective equipment to detect the presence of persons”

sounds that protective equipment detects the presence but does not detect the approach of persons. Protective

equipment detects the approach of persons. To clarify this we propose to change the title as below.

Proposed change

“Safety of machinery – Application of protective equipment to detect detecting the presence and approach of

persons”

4 Proposal to add definitions We propose to add the following definitions in clause 3.

Proposed additions as follows

3.xxx

Actuation

Initiating or starting of the operation of an equipment or a function

NOTE 1 Actuation of an ESPE means that the detection of an object causes the OSSD to go to OFF state. (See

e.g.3.14.)

NOTE 2 Actuation of a sensing device means that the sensor detects the object and outputs the detection signal

to cause the OSSD to go to OFF state. (See e.g. 3.1.37, 4.7.4.)

NOTE 3 Actuation of a trip device means that an object is detected by the trip device and cause the device to trip.

(See e.g. 4.4.23.)

NOTE 4 Actuation of a safeguarding function means that the safeguarding such as a guard interlock operates to

cause the machine to stop responding to the force applied to the safe guarding. (See e.g. 4.7.6.)

NOTE 5 Actuation of a mat means that that the mat detects a person or an object and outputs the detection signal.

(See 6.4.2.4 and 6.4.2.5.)

3.xxx

Circumvention (of protective equipment)

Action to approach a hazardous zone without being detected by the protective equipment by penetrating, bypassing

or manipulating the detection zone. (See 4.5.4.)

5 Proposal to enhance the description of mute dependent override We propose to enhance the description for mute dependent override. We’d ask the MT to consider the

underlined texts below.

4.7.3.2 Mute dependent override function Mute dependent override function allows a manual operation of the machine in order to clear material in the

detection zone of the protective equipment. The override function is only available when at least one muting

sensor is activated. See also 9.2.4 of IEC 60204-1.

Override function means to manually suspend or bypass the protective function temporarily. Override of the

ESPE function means that the operator imperatively makes the OSSD(s) to go or to keep the ON-state by

－163－

his/her manual action when the penetration of detection zone is detected.

Override function is different from muting. Muting is an automatic suspension of protective function and override

function is a manual suspension of protective function.

Mute dependent override function is a conditional override where the override function is possible only when

the object is being detected by at least one muting sensor.

Fig.1 illustrates a mute dependent override function. Muting is initiated by muting sensors A and B. When both

muting sensors A and B detect the material before the ESPE detect that material correct muting is established

and the material can proceed to the hazardous area without stopping the machine. If the location of the material

is irregular as shown in Fig.1 the material is detected by the ESPE before two muting sensors A and B detect it

and the machine stops because muting is not initiated. The override function allows the operator to return the

OSSD(s) to the ON-state and resume the machine operation after repositioning the material correctly. This

override function is possible because at least one muting sensor (sensor B in this case) is activated.

6 Proposal to add description for blanking In response to MT62046’s proposal NO.3 to add blanking example we propose our texts at hand. W

e’d ask the MT to arrange our underlined texts with the existing texts of 6.1.3.3.

6.1.3.3 Blanking

Blanking is an optional function allowed for ESPE in particular for AOPD. Blanking means the function, which does

not turn off the OSSD(s) even if the beam(s) is interrupted in the specific part (blanking area) defined in the detection

zone of ESPE.

Blanking function can be necessary in AOPD application for a machine which needs feeding material into the

hazardous area and/or taking work pieces out of the hazardous area while the machine is operating.

Blanking is classified into two types i.e. fixed blanking and floating blanking. In both blanking system a monitored

blanking is usually adopted for safety.

Monitored blanking

It is very dangerous that a person or a part of a person can approach the hazardous area through the blanked area

while the machine is operating. The blanked area should only allow the penetration by the intended objects and be

protected from human penetration. During machine operation the blanked area should be always occupied by the

intended objects not to create an unprotected part in the detection zone. To assure this monitored blanking is used.

Monitored blanking is a blanking system that employs a monitoring function to determine whether the blanked area is

being occupied by the intended obstacle and makes the OSSD(s) go to the OFF-state as soon as the blanked area is

absent of occupying objects. Monitoring of the occupation of the blanked area by the objects is usually achieved by

detecting the interruption of the light beam(s) for that blanked area. The monitoring function works in the opposite

mode of normal detecting function.

Fixed blanking

Fixed blanking is a technique wherein the locations of the blanked area(s) of the detection zone do not change during

operation. The detection capability of the other parts of the detection zone remains unchanged. A blanked area is

defined by one or more light beams. The OSSD(s) will not go to the OFF-state when the defined beam(s) are kept

interrupted. On the contrary, in case of monitored blanking, when the defined beam(s) are not interrupted the

OSSD(s) shall go to the OFF-state. In this manner the intended objects (material, work piece) can move through the

blanked area without causing the OSSD(s) to go to the OFF-state (without stopping the machine operation) and

human approach to the hazardous machine operating area through the blanked area is prevented.

Fig. 1 shows an example of fixed blanking applied for a conveyer system. The conveyer must always occupy the

blanked area. The part of the blanked area not occupied by the conveyer must be protected by such object as a fixed

mechanical barrier.

－165－

Floating blanking

Floating blanking is a technique wherein the blanked area of the detection zone follows the location of a moving

object(s) during operation. The detection capability of the other areas remains unchanged.

A blanked area can be defined by arbitrary one or more light beam(s). When the defined numbers of beams are

interrupted by the intended object (material or work piece) the OSSD(s) will not go to the OFF-state. Floating blanking

is used for an application where the material or work piece changes the position. Fig. 2 shows an example of floating

blanking applied for roll winding.

Monitored blanking for floating blanking system monitors the state of the beam interruption(s) in the blanked area. If

the beams are not interrupted as intended the OSSD(s) shall go to the OFF-state.

There are two kinds of monitored blanking for a floating blanking with multiple blanked beams. One kind of floating

blanking defines the blanked area by adjoining beams. In this kind it is monitored whether the interrupted beams

adjoin each other or not. If the separation between interrupted beams are found the OSSD(s) shall go to the

OFF-state.

Another kind of floating blanking defines the blanked area by the number of blanked beams which may not be

necessarily adjoining each others. In this kind the total number of interrupted beams is monitored. When the total of

interrupted beams exceeds the defined number, the OSSD(s) shall go to the OFF-state.

It is important to take into account the size of the blanked area when calculating the safety separation distance for

persons.

Fig.1 Example of fixed blanking

Fig. 2 Example of floating blanking

－166－

Existing texts

To prevent possible misuse, blanking shall not be available except when necessary for the operation of the machine.

Blanking can be used to allow the presence of parts of the work piece or of the machine in the detection zone when

safety is maintained by other measures, for example:

��the blanked area is continuously and entirely occupied by material, fixtures, fixed guards or removable interlocking

guards (see Figure 8); or

��the light curtain operates in ‘opposite mode’ for all fixed blanked beams, i.e. the light curtain will go to the OFF-state

if an area that should be obstructed becomes clear, or

��the separation distance is increased in accordance with ISO 13855 due to the modified detection capability.

Information on the modified detection capability is needed from the AOPD manufacturer.

The installation shall be such as to minimize the possibility of loss of detection capability caused by reflective surfaces

in the blanked zone (see also 6.1.1).

Annex B (Appendix to 44/590A_JP) (normative)

Protection against indirect contact in TT-systems (Derived from IEC 60364-4-41:2006 2005 and IEC 60364-6-61:2006)

B.1 Requirements for TT Systems

B.1.1 Connection to earth

All exposed-conductive-parts and all extraneous conductive parts likely to be touched shall be bonded to the protective conductor or directly to the PE terminal. The PE terminal shall be connected to one or more earthing electrodes as necessary to obtain a sufficiently low earth electrode resistance. Where a separate functional earthing circuit is provided for the common connection of sensitive equipment, the functional earth terminal shall be connected to the earth electrode(s). The neutral point or the mid-point of the power supply system shall be earthed. If a neutral point or mid-point is not available or not accessible, a line conductor shall be earthed.

B.1.2 Residual current protective devicea) Residual current devices (RCDs) shall be provided for earth fault protection in accordance with the following: it shall disconnect the affected circuit within a sufficiently short time in the event of a fault between a live part and an exposed conductive part or an extraneous conductive part;b) the circuit shall also be protected by an overcurrent protective device;c) the disconnection time shall be in accordance with Table B.1 for circuits not exceeding 32A, and not

more than 1 second for circuits 32A or greater;d) RA x I.n �� 50 V

1) Where I.n is the rated residual operating current of the RCD.2) Where RA is the impedance in ohms of the fault loop comprising:

a) the source,b) the line conductor up to the point of the fault,c) the protective conductor of the exposed-conductive-parts,d) the earthing conductor,e) the earth electrode of the installation andf) the earth electrode of the source;e) The maximum value for RA at the final installation shall not exceed 100 ohms the

requirements of d) will be satisfied if the fault current is limited to 500mA when RA does notexceed 100 ohms.

NOTE 1 The disconnection times specified in Table B.1 relate to prospective residual fault currents significantly higher than the rated residual operating current of the RCD (typically 5 I.n).B1.2 Fault protection for TT systemsB.1.2.1 GeneralGenerally in TT systems, RCDs shall be used for fault protection. Alternatively, over-current protective devices may be used for fault protection provided a suitably low value of Zs is permanently and reliably assured.B1.2.2 Protection by Residual current protective device (RCD)Where a residual current protective device (RCD) is used for fault protection, the following conditions shall be fulfilled:i) the disconnection time as required by table B.1, Exception: disconnection time is not exceeding 1s is

permitted for distribution circuits and for circuits not covered by table B.1, andii) RA x I�n � �50 V

whereRA is the sum of the resistance in ��of the earth electrode and the protective conductor for the exposed conductive-parts,I�n is the rated residual operating current of the RCD.NOTE 1 Fault protection is provided in this case also if the fault impedance is not negligible.NOTE 2 Where discrimination between RCDs is necessary see 535.3 of IEC 60364-5-53.

－182－

NOTE 3 Where RA is not known, it may be replaced by ZS.NOTE 4 The disconnection times in accordance with Table B.1 relate to prospective residual fault currents significantly higher than the rated residual operating current of the RCD (typically 5 I�n).NOTE 5 in Japan, permissible maximum value of RA is regulated (e.g. Uo > 300V, RA shall be less than 10 �)B1.2.3 protection by over-current protection deviceWhere an over-current protective device is used the following condition shall befulfilled:

Zs�x��/a � UowhereZs is the impedance in �� of the fault loop comprising

��the source,��the line conductor up to the point of the fault,��the protective conductor of the exposed-conductive-parts,��the earthing conductor,��the earth electrode of the installation and ��the earth electrode of the source;

Ia is the current in A causing the automatic operation of the disconnecting device within the time specified in table B.1. Exception: disconnection time is not exceeding 1s is permitted for distributioncircuits and for circuits not covered by table B.1;Uo is the nominal a.c. or d.c. line to earth voltage.

TT 0,3 Note 1 0,2 0,4 0,07 0,2 0,04 0,1

Where in TT systems the disconnection is achieved by an overcurrent protective device and the protective equipotential bonding is connected to all extraneous-conductive-parts within the fabrication equipment, the maximum disconnection times applicable to TN systems may be used.

Uo is the nominal a.c. or d.c. line to earth voltage.

NOTE Disconnection can be required for reasons other than protection against electric shock.

B.1.3 Verification of protection by automatic supply disconnection using a residual current protective device

Protection against indirect contact in a TT system by automatic supply disconnection using a residual current protective device shall be verified by the following test, inspection and measurement.��Inspection of the rated residual current for tripping, and the disconnecting time of the residual current protective device, verification that the residual current protective device has been tested in accordance with a relevant IEC standard, and inspection of the connectiions to the residual current protective device and protective bonding circuit, and measurement of the fault loop impedance of the protective bonding circuit connected to the exposed conductive parts of the semiconductor fabrication equipment. The earth resistance shall be less than 100 �.

NOTE For the verification of performance of a residual current protective device and measurement of earth fault loop impedance, see IEC 60364-6.

INTERNATIONAL ELECTROTECHNICAL COMMISSION

TECHNICAL COMMITTEE NO.44: SAFETY OF MACHINERY – ELECTROTECHNICAL ASPECTS

REVISION OF IEC60204-1 Ed 5 (2005)

At the meeting in Paris in September 2007 TC 44 agreed that a full revision of IEC 60204-1: 2005 would commence in 2008 and be completed by 2013. This to include consideration of the Common Modifications to EN 60204-1: 2006 (44/570/RM minute 7.4).

To commence this process proposals relating to emergency stop and comments from the Japanese national committee are attached for consideration. National committees are requested to submit their comments on these proposals together with any further proposals they may have for revision of IEC 60204-1 through the IEC electronic voting system by:

Requirements for provision of emergency stop devices on cableless controllers The proposals below have been drafted by the CLC/TC 44X study group on cable less emergency stop devices to add extra requirements to IEC 60204-1 to specify what features of a cable less control are necessary for it to be useable as an e-stop. It is suggested that these provisions could be included in clause 9 either under cable less controls or emergency stop or as a separate subclause.

Conditions for provision of a cableless emergency stop device Cableless emergency stop devices shall only be provided when a risk assessment has shown that they are not less suitable than wired emergency stops. Cableless emergency stop devices shall only be provided when there can be no additional risk from unwanted stopping. The safety-related performance of the cableless communication shall be suitable for the application (See IEC 62061 or ISO 13849).

Docking station. A docking station shall be provided. When the controller is placed in the docking station at least the emergency stop function shall be available. A wired emergency stop device shall be available at the docking station.

Automatic stop on loss of signal An automatic stop command shall be generated when correct control signals are not received, including loss of communication. This command shall be generated within a time determined by a risk assessment at the machine, but in no case exceeding 550 ms.

The stop category of the automatic stop may be different to that of the emergency stop, for example the automatic stop may be stop category 1 and the emergency stop category 0.

The cableless controller shall provide a warning to the operator when the communication signal is low, e.g. to due approaching the limit of transmission range or a low battery voltage.

Response time The response time between actuation of the emergency stop button and the generation of the stop command shall not exceed 10ms.

Span of control There shall be a clear relationship between the cableless cotroller and the machine it controls.

Unless otherwise indicated by a risk assessment there shall be a clear indication whether the cableless control station is active or inactive.

Avoidance of spurious operations Means shall be provided (e.g. coded transmission) to prevent crosstalk/spurious operations.

ResetReset of the emergency stop condition shall only be possible when complete potentially hazardous area of machine can be seen to be in a safe state. It can be necessary to reset the emergency stop actuator on the controller, the emergency stop function of the cableless communication system, and then the machine's control system. (2-step or 3-step reset?)

Means shall be provided for safe recovery from the emergency stopped condition after loss or total failure of the cableless controller.

Annex F (informative)

Guide for the use of this part of IEC 60204 F.1 General This part of IEC 60204 gives a large number of general requirements that may or may not be applicable to the electrical equipment of a particular machine. A simple reference without any qualification to the complete standard IEC 60204-1 is therefore not sufficient. Choices need to be made to cover all requirements of in applying requirements covered by this part of IEC 60204. A technical committee preparing a product family or a dedicated product standard (type C in CEN), and the supplier of a machine for which no product family or dedicated product standard exists, should use this part of IEC 60204:

(To eliminate complication and to make consistency with Table F.1 change the text as follows.) a) by applying (selecting) appropriate clauses (requirements) without modification; or b) by applying additional requirements (e.g. from other standard); or c) by applying different (modified) requirements (modifications are made in accordance with other relevant

standards where the particular requirements for the equipment of the machine are adequately covered by those standards).

a) by reference; and b) by selection of the most appropriate option(s) from the requirements given in the relevant Clauses; and c) by modification of certain Clauses, as necessary, where the particular requirements for the equipment

of the machine are adequately covered by other relevant standards,

providing the options selected and the modifications made do not adversely affect the level of protection required for that machine according to the risk assessment..

When applying the three principles a), b) and c) listed above, it is recommended that: – reference be made to the relevant Clauses and Sub-clauses of this standard: 1) that are

complied with, indicating where relevant the applicable option; 2) that have been modified or extended for the specific machine or equipment requirements; and

– reference be made directly to the relevant standard, for those requirements for the electrical equipment that are adequately covered by that standard. In all cases, expertise is essential to be able to: – perform the necessary risk assessment of the machine; – read and understand all of the requirements of this part of IEC 60204; – choose the applicable requirements from this part of IEC 60204 where alternatives are given; – identify alternative or additional particular requirements that differ from or are not included in the requirements of this part of IEC 60204, and that are determined by the for specific machine and its use; and – specify precisely those particular requirements.

Figure 1 of this part of IEC 60204 is a block diagram of a typical machine and can be used as the starting point of this task. It indicates the Clauses and Subclauses dealing with particular requirements/equipment. However, this part of IEC 60204 is a complex document and Table F.1 can help identify the application options for a particular machine and gives reference to other relevant standards.

Annex X(normative)

Protection against indirect contact in TT-systems (Derived from IEC 60364-4-41:2005 and IEC 60364-6:2006)

X.1 General In a TT-system installation protection against indirect contact by means of automatic supply disconnection can depend either on -over-current detection, or - residual current detection.

However, in TT-systems, the automatic disconnection by residual current detection is generally preferred to the disconnection by over-current detection. Automatic supply disconnection using an over-current detection device should not be adopted except automatic disconnection is assured by the detection of the increased current in the event of an insulation fault (earth fault).

An over-current detection device having an inverse time characteristic shall only be allowed for power distribution circuits supplying a group of machines where the possibility of indirect contact to an exposed conductive part is sufficiently small.

In a machine that has an exposed conductive part(s) which can be easily touched by a person and can attain dangerous potential due to an insulation fault the automatic disconnection time shall be in accordance with Table B.1.

X.2 Condition of automatic supply disconnection Where protection against indirect contact depends on automatic supply disconnection the supply shall be automatically disconnected within a sufficiently short disconnecting time from the circuit or equipment in the event of an insulation fault between a live part and an exposed conductive part or a protective conductor in the circuit or equipment.

Automatic supply disconnection shall conform to the following condition.

RA × Ia � 50V (1)

where, RA is the total resistance of the earth electrode and the protective conductor connected to the exposed conductive part.

Ia is the rated current causing the automatic operation of the protective device. Where protective device is a residual current protective device Ia is the rated residual current to cause tripping within a time specified by Table B.1. Where the protective device is an over-current protective device Ia is either,

-for a protective device having inverse time characteristic, the current causing automatic disconnection within 5 seconds. -for a protective device having an instantaneous tripping characteristic, the minimum current causing automatic tripping within a time specified by Table B.1.

Table B.1 specifies the maximum disconnecting times with respect to the touch voltage Ut.Table B.1 – Maximum disconnecting times for TT systems

Ut (V) Allowable maximum disconnecting time (s) 120 0.3

－218－

230 0.2 277 0.1 400 0.07 500 0.04 NOTE 1 Ut is the estimated touch voltage (r.m.s.) in the event of indirect contact. When Ut

cannot be estimated the nominal voltage to earth Vo (r.m.s.) may be used instead of Ut. For intermediate values of voltage, the next higher value in the above table is to be used. NOTE 2 This table derives from figure 2 of IEC 61200-413.

In applying Table B.1 for a residual current protective device the earth resistance of the earth system (RA) shall be smaller than 100 �.

For the purpose of discrimination, S-type residual current protective devices (see IEC 61008-1 and IEC 61009-1) may be used in series with general type residual current protective devices. To provide discrimination with S-type residual current protective devices, a disconnecting time not exceeding 1 s is permitted only in power distribution circuits.

Where the above requirements corresponding to the type of protective device is not fulfilled a supplementary equipotential bonding shall be provided.

NOTE 3 In TT system an over-current protective device can be used only where RA is sufficiently low. Generally Ia of a residual

current protective device is of the order of mA. While Ia of an over-current protective device is of the order of A and should beset

larger than starting rush current. Therefore, conforming to equation (1) by using an over-current protective device is usually difficult.

For example, in case Ia = 50 A RA must be smaller than 1 �. Achieving an earth system with less than 1 � of earth resistance is not

always easy. For this reason protection against indirect contact in TT system is generally provided by a residual current protective

device.

X.3 verification of the condition that protection is achieved by automatic supply disconnection using a residual current protective device For the verification that a protective measure against indirect contact by means of an automatic supply disconnection using a residual current protective device is assured, at least following test, inspection and measurement shall be implemented.

-inspection of the rated residual current for tripping and disconnecting time of the residual current protective device, performance test of the residual current protective device, and inspection of the tight connection of connecting points (welding, screw terminal etc.) on the residual current protective device and protective bonding circuit.

Measurement of earth resistance of the earthling system connected to the exposed conductive parts of the electrical equipment or the machine. The earth resistance shall be smaller than 100�.

Exception Where the earth system is periodically measured and the length and the cross-sectional area of the extraneous protective conductor can be confirmed in the operating condition it may be sufficient to inspect the data sheet and the continuity (connection) of the protective conductor.

NOTE 4 The verification of performance of a residual current protective device and measurement procedure of earth resistance is

given in the Annex of IEC 60364-6.

1. Opening of the meeting The Chairman welcomed delegates to São Paulo and thanked the Brazilian national committee for their hospitality and excellent organisation of the meeting. He congratulated Mr Dieterle (who was not present) for his IEC 1906 award which was given with the following citation: “Mr. Dieterle receives this award for his outstanding contribution to the development of the ESPE -Product standard series IEC 61496 and the application standard IEC 62046.”

2. Approval of the Agenda (44/583A/DA) The agenda was approved after the green papers, which had been loaded on Infosys, has been linked with their agenda items. These are circulated separately in 44/592/MTG.

3. Minutes of the meeting of IEC/TC44 held in Paris, France on 12th -13th September 2007 (44/570/RM).

The minutes were noted.

4. Matters arising from the Minutes of the last meetingNone

5. Report from ACOS – Mr Friedrich HarlessThe Chairman (as Chairman of ACOS) took delegates through his report which is included in 44/592/MTG. He drew attention to the ACOS Workshop IX which would be held on 18 and 19 May 2009 in Milan, Italy.

6. Reports from Working Groups

－225－

The reports in 44/588A/INF were noted in connection with the items listed below.

6.1 MT 62046 Application of PSPE to machinery IEC 62046: Safety of machinery - Application of personnel sensing protection equipment to machinery (PSPE) - Convenor: Mr Peter StillThe report from the convenor contained in 44/592/MTG was noted. Mr Webster reported there would probably be one or two meetings to produce the CD which was expected to be issued by the end of 2009 with an MCR to start the project. The document would remain a TS.

6.2 WG7: Safe control systems for machinery - Convenor: Mr Steve FrostA revised WG 7 Convenors report and a DE proposal which are circulated in 44/592/MTG were noted in connection with this item. It was noted that the work of the liaison group was now focussed on the development of a Technical Report on the application and use of IEC/EN 62061 and EN ISO 13849-1. This work had progressed well within the ISO/TC199/WG8 & IEC/TC44/WG7 Liaison Group and had resulted in the development of draft documents that are scheduled for completion at a meeting which would take place before the end of the year. It was considered that ISO 13849-1 was generally suitable for individual machines while IEC 62061 was better for complex installations. Delegates discussed the merits of awaiting further experience to develop these standards or proceeding with the revision process. Mr Goedicke observed that EN 954 was still being used as it was the easiest way to comply with the Machinery Directive. The Chairman added that the standard used is normally specified by the customer. It was noted that the document would be submitted for vote as a TR which was informative and being a dual logo document would be numbered in the 8000 series.
