The miniTwin2 safety light curtain must be installed, connected, commissioned and serviced only by qualified safety personnel. Qualified safety personnel are defined as

persons who …

 due to their specialist training and experience have adequate knowledge of the power-

driven equipment to be checked

and

 have been instructed by the responsible machine owner in the operation of the machine

and the current valid safety guidelines

and

 are sufficiently familiar with the applicable official health and work safety regulations,

directives and generally recognized engineering practice (e.g. DIN standards, VDE stipulations, engineering regulations from other EU member states) that they can assess the work safety aspects of the power-driven equipment

and

 who have access to these operating instructions and who have read them.

As a rule these are qualified safety personnel from the ESPE manufacturer or also those

persons who have been appropriately trained at the ESPE manufacturer, are primarily involved in checking ESPE and are allocated the task by the organisation operating the ESPE.



WARNING

2.2 Applications of the device

The miniTwin2 safety light curtain is an electro-sensitive protective equipment (ESPE) type 2 according to IEC 61496A1. The safety level of the miniTwin2 corresponds to category 2 PL c according to EN ISO 13849A1 and SIL1 according to IEC 61508.

The miniTwin2 safety light curtain is suitable for:

 hazardous point protection (finger and hand protection)

 hazardous area protection

 access protection

Access to the hazardous point must be allowed only through the protective field. The

plant/system is not allowed to start as long as personnel are within the hazardous area. Refer to section 3.3 “Application examples” on page 15 for an illustration of the protection

modes.

Only use the safety light curtain as an indirect protective measure!

An opto-electronic protective device provides indirect protection, e.g. by switching off the power at the source of the hazard. It cannot provide protection from parts thrown out, nor

from emitted radiation. Transparent objects are not detected.

Product description

3.5.2 External device monitoring (EDM)

The EDM checks if the contactors actually de-energize when the protective device responds. If you activate external device monitoring, then the miniTwin2 checks the

ontactors after each interruption to the light path and prior to the machine restart. The

c EDM can so identify if one of the contactors has welded, for instance. In this case the

external device monitoring places the system in a safe operational state. The OSSDs are

ot re-activated in this case.

4.1 Determining the minimum distance

The safety light curtain must be mounted with sufficient minimum distance:

 from the hazardous point

 from reflective surfaces



WARNING

No protective function without sufficient minimum distance!

The reliable protective effect of the safety light curtain depends on the system being mounted with the correct minimum distance from the hazardous point.

4.1.1 Minimum distance from the hazardous point

A minimum distance must be maintained between the safety light curtain and the

hazardous point. This ensures that the hazardous point can only be reached after the dangerous state of the machine has been completely stopped.

The minimum distance as per EN ISO 13855 and EN ISO 13857 depends on:

 stopping/run-down time of the machine or system

(the stopping/run-down time is shown in the machine documentation or must be determined by taking a measurement.)

 response time of the entire protective device, e.g. miniTwin2 consisting of host and

guest (response times see 9.1 “Data sheet” on page 64)

 reach or approach speed

 resolution of the safety light curtain and/or beam separation

 other parameters that are stipulated by the standard depending on the application

Under the authority of OSHA and ANSI the minimum distance as specified by ANSI B11.19:2003C04, Annex D and Code of Federal Regulations, Volume 29, Part 1910.217 … (h) (9) (v) depends on:

point

How to calculate the minimum distance S according to EN ISO 13855 and EN ISO 13857:

The following calculation shows an example calculation of the minimum distance.

Depending on the application and the ambient conditions, a different calculation may be necessary.

 First, calculate S using the following formula:

S = 2000 × T + 8 × (d – 14) [mm]

Where …

T = Stopping/run-down time of the machine

+ Response time of the protective device after light path interruption [s]

d = Resolution of the safety light curtain [mm]

S = Minimum distance [mm]

The reach/approach speed is already included in the formula.

 If the result S is  500 mm, then use the determined value as the minimum distance.

 If the result S is > 500 mm, then recalculate S as follows:

S = 1600 × T + 8 × (d – 14) [mm]

 If the new value S is > 500 mm, then use the newly determined value as the minimum

distance.

 If the new value S is  500 mm, then use 500 mm as the minimum distance.

Mounting

Example:

Stopping/run-down time of the machine = 290 ms

esponse time after light path interruption = 30 ms

Resolution of the safety light curtain = 14 mm T = 290 ms + 30 ms = 320 ms = 0.32 s

S = 2000 × 0.32 + 8 × (14 – 14) = 640 mm S > 500 mm, for this reason:

S = 1600 × 0.32 + 8 × (14 – 14) = 512 mm

How to calculate the minimum distance Dsaccording to ANSI B11.19:2003C04, Annex D and Code of Federal Regulations, Volume 29, Part 1910.217 … (h) (9) (v):

Note

The following calculation shows an example calculation of the minimum distance.

Depending on the application and the ambient conditions, a different calculation may be necessary.

 Calculate D

= Hs× (Ts+ Tc+ Tr+ T

using the following formula:

) + D

Where …

= The minimum distance in inches (or millimetres) from the hazardous point to the

protective device

= A parameter in inches/second or millimetres/second, derived from data on

approach speeds of the body or parts of the body. Often 63 inches/second (1600 mm/second) is used for H

= Stopping/run down time of the machine tool measured after the final control

element

= Response time of the control system

= Response time of the entire protective device after light path interruption

= Additional time to compensate for the lack of brake wear monitoring

Note

Any additional response times must be accounted for in this calculation.

= An additional distance added to the overall minimum distance required. This

value is based on intrusion toward the hazardous point prior to actuation of the

electro-sensitive protective equipment (ESPE). Values range from 0.25 inches to 48 inches (6 to 1220 millimetres) or more depending on application.

Example:

For perpendicular protection using an opto-electronic protective device with an

object sensitivity (effective resolution) less than 2.5 inches (64 millimetres), D

can be approximated based on the following formula:

(inches) = 3.4 × (effective resolution – 0.276), but not less than 0.

their de-energized position after the protective device has responded. 24 V is then applied at the input of the EDM. If 24 V is not present after the response of the protective device,

then one of the contact elements is faulty and the external device monitoring prevents the machine starting up again.

 If you connect contacts to be monitored to the external device monitoring input (EDM),

then EDM is configured automatically during commissioning (see section 6.6

“Configuration of the external device monitoring (EDM)” on page 56).

 You must connect the contacts to be monitored together on the external device

monitoring input (EDM) on a miniTwin2.

Both Twin Sticks must always be switched on at the same time. If you take one of the Twin

Sticks out of operation, you must briefly switch off the second Twin Stick prior to switching on again.

After switching on the miniTwin2 safety light curtain runs through the power-up cycle. The LED display indicates the device status during the power-up cycle.

The displays have the following meaning:

ecure the system. No dangerous state possible!

Ensure that the dangerous state of the machine is (and remains) switched off! During the alignment process, the outputs of the safety light curtain are not allowed to have any

effect on the machine.

After the safety light curtain has been mounted and connected, the two Twin Sticks must

be aligned in relation to each other. The light beams emitted by the sender optics must hit the receiver optics accurately.

The miniTwin2 safety light curtain signals the alignment quality with the aid of the blue LEDs (1 to 5), i.e. how well the two Twin Sticks are aligned with each other. If all LEDs

illuminate, the alignment is optimal, if no LED illuminates, the alignment is poor.

If three of the blue LEDs illuminate, then the safety light curtain changes to green. You

then have approx. 2 minutes to optimize the alignment of the Twin Sticks.

When using deflector mirrors, the effective scanning range is reduced (see section 9.1 “Data sheet” on page 64).

Do not use deflector mirrors if the formation of droplets or heavy contamination of the deflector mirrors is to be expected!

The formation of droplets of heavy contamination can be detrimental to the reflection behaviour. The protective function of the system will be affected and the system will thus

become unsafe. This would mean that the operator is at risk.
