TYPICAL APPLICATIONS

• Paper-cutting machines

• Pick-and-place robots

• Light electronic assemblying machines

• Good lifts

• Small carousels

The FF-LS equipment is an infrared multibeam device designed to protect operators

working on dangerous machines. The FF-LS equipment features are ideal for the

protection of work stations on small machines such as paper-cutting machines or

pick-and-place robots.

The permanent self-checking electronic process is based upon a microprocessor

technology and meets the requirement of the IEC/EN 61496- parts 1 & 2 European

standards for Type 4 electrosensitive protective equipment.

It has been examined by the TÜV who granted the EC type examination certificate.

The equipment consist of a pair of sensing units connected to a separate control

unit via a RS-485 connection.

Each sensing unit is made of a row of emitting circuits alternating with receiving

circuits. These circuits are housed in an extremely small aluminium extruded pro-

file: the cross section is only 12 mm x 19,7 mm / 0.47 in x 0.77 in.

The two sensors are matched to each other by individual coding to reduce risk of

cross talk with other light curtains and to improve immunity to welding splashes.

The control unit supplies the sensing units, controls the correct operation of the

scanning circuits and transmits the resulting commands to the machine control

circuitry through its two relay outputs.

The equipment can operate according to two different mode: the automatic mode,

the start & restart interlock mode.

In addition, the control unit is featured with a test input to trigger the output relays

switching and thus check the correct operation of the final switching devices when-

ever needed. In case of failure, the control unit provides optical and acoustic signals

to ease failure diagnostic.

Safety distance

: Minimum safety distance (mm / in)

t1 : Response time of the light curtain (s)

t2 : Stopping time of the equipment guarded by the light

curtain, including all mechanical, electromechanical and

electronic parts (s)

H : Height of the detection zone above the floor (mm / in)

The safety distance between the protection field and the dangerous zone

should be large enough to ensure that if the protection field is entered,

the dangerous zone cannot be reached before the hazardous movement

is arrested. For the safety distance, the following formula applies:

•Normal approach

Europe (EN 999)

S ≥≥

≥≥

≥ 2000 (t1 + t2) + 128 (mm), with S ≥ ≥

≥ ≥

≥ 100 mm

(or S ≥ ≥

≥ ≥

≥ 78.8 t1 + t2) + 5 (in), with S ≥ ≥

≥ ≥

≥ 3.9 in

If the result of this calculation is greater or equal to 500 mm /

19.7 in, then use the following formula:

S ≥≥

≥≥

≥ 1600 (t1 + t2+ 128 (mm), with S ≥≥

≥≥

≥ 500 mm

(or S ≥≥

≥≥

≥ 63 (t1 + t2) + 5 (in), with S ≥≥

≥≥

≥ 19.7 in

US (OSHA 29 CFR 1910.217, ANSI B11.19 1990

Ds ≥≥

≥≥

≥ 63 (t1 + t2) + 3.08 (in) Ds = S

•Parallel approach

Europe (EN 999)

S ≥≥

≥≥

≥ 1600 (t1 + t2) + (1200-0.5H) (mm)

where (1200-0.4H) ≥≥

≥≥

≥ 850 mm

(or S ≥≥

≥≥

≥ 63 (t1+t2) + 47.3 - 0.4H0 (in)

where (47.3 - 0.4 ) ≥≥

≥≥

≥ 33.5 in)

If H is greater than 300 mm / 11.82 in, the risk of access from below

must be taken into account. For this barrier, the minimum height

allowed is H min. = 0 mm and the maximum height allowed is

H max. = 1 000 mm / 39.4 in.

•Angled approach

Europe (EN 999)

30° < αα

αα

α < 90°

If the angle is greater than 30°, the approach should be considered

as normal, and one of the above-mentioned formulas should be

used.

0° < αα

αα

α ≤≤

≤≤

≤ 30°

If the angle is less than or equal to 30°, the approach should be

considered as parallel and one of the above-mentioned formulas

should be used. In this case the minimum height allowed is P min.

= 0 mm and the max. height allowed is H = 1 000 mm / 39.4 in max.

However, if P > 300 mm / 11.82 in, the risk of inadvertent access from

below must be taken into account.

Connection diagram

(1) - Supply (to be ordered separately):

The use of one of these supplies brings

the galvanic isolation which is necessary

to the system for a use conform to

IEC/EN 61496 - 1 standard.

FF-LSZUS0605 (230 Vac / 24 Vdc),

FF-LSZUS0606 (115 Vac / 24 Vdc)

(2) - Test duration: The contact must be

closed during 100 ms as a minimum.

(3) - The push-button must remain closed

during 200 ms at least. It takes 500 ms for

the system to restart after releasing the

push-button.

(4) - If additional contacts are needed or if

the switching capacity must be increased,

use the connection diagram given or an

example.
