This symbol indicates an important personal safety warning. Failure to

comply with the warning may result in very high risk for exposed personnel.

INTRODUCTION

The ReeR control unit is a safety device complying with

IEC 61496-1, IEC 61496-2 specifications. When connected to a Ilion or

a ULISSE/ILION UPC safety photocell, it forms a type 2 ESPE (Electro-

sensitive Protective Equipment).

Possible connections: from 1 to 4 photocells

Restart manual or automatic selectable

2 N.O. outputs with guided contact safety relays

1 system monitor PNP output

1 external contactors feedback input

Connected safety photocells periodic autotest (every 5s) .

Possible connections: from 1 to 4 photocells

Manual or automatic selectable Restart

2 N.O. outputs with guided contact safety relays

1 system monitor PNP output

1 external contactors feedback input

Muting function with two sensors logic

1 Muting function enable input

1 muting lamp output

Muting Override function integrated

Selectable muting timeout

Connected safety photocells periodic autotest (every 5s).

The control unit also guarantees that:

the output lines are open if the photocell is intercepted;

the output lines are enabled only with correct response

times;

in manual mode, maintenance of the RESTART contact

closed is not interpreted as AUTO mode.

For safe use of the device, it is essential to read and understand the contents

of this handbook.

Failure to comply with the prescriptions indicated in this handbook may result

in very high risks for the operating personnel of the machine protected.

Carefully consider the risks analysis of the application and the

legislation of the barrier application Country to establish if the

application is compatible with the safety category 2.

NEW SAFETY PARAMETERS FOR TYPE 2 BARRIERS AND

MANDATORY LABELLING



With the publication of Edition 3 of the harmonized EN 61496-1

standard it is no longer possible to use a Type 2 safety light barrier

for safety functions assessed as SIL 2 / PL d.

If a safety level of SIL 2 / PL d (or higher) is required and it is

nevertheless intended to use a safety light barrier, then it will be

necessary to use a Type 4 safety light barrier.

This regulatory requirement derives from the fact that the reduction of

risk that can be obtained via a photoelectric safety barrier is not only

a function of the safety level of its electronic parts, but is also

determined by its systematic capabilities (for example:

environmental influences, EMC, optical performance and detection

principle).

The systematic capability of a Type 2 photoelectric barrier may in fact

not be sufficient to ensure adequate risk reduction for SIL 2 / PL d

applications.

The standard also establishes that the labelling of Type 2 safety

barriers must indicate such limitation to SIL 1 / PL c.

The PFHd values declared for the electronic control part of the

device, on the other hand, are not limited and therefore it is possible

to use the PFHd value provided by the manufacturer of the device in

the global assessment of the safety function, even if it exceeds the

SIL 1 / PLc range.

AUTOMATIC

In this operating mode, the outputs of the control unit follow the

status of the photocell:

•with the protected area free (outputs of the photocells active), the

relay outputs of the control unit are active.

•with the protected area occupied (outputs of the photocells de-

activated), the relay outputs of the control unit are de-activated.

Figure 1

Use in manual mode (start/restart interlock activated) is mandatory in the

case in which the safety device controls an access protecting a danger zone

and once a person has passed through the opening, he/she may remain in

the danger zone without being detected (use as trip device according to

IEC 61496). Failure to comply with this rule may result in very serious risks

for the persons exposed.

Check correct functioning of the entire safety system (control unit+photocell)

following each re-installation. In particular, if the original operating mode was

Manual, check that the unit has been reconfigured in this mode.

MANUAL

In this operating mode, the outputs of the control unit are activated

only if the protected area is free and after sending the RESTART signal

to the control unit using the push-button or by means of a specific

command on the RESTART input (terminal 4).

Once the protected area has been occupied, the relay outputs are de-

activated. The sequence described above must be repeated in order to

re-activate them.

The RESTART command is active with a 0VDC ---> +24VDC transition.

The minimum duration of the command is 100 ms.

Figure 2

CONNECTION OF EXTERNAL CONTACTORS K1 and K2

Control of external contactors K1K2 can be activated in both operating

modes. If this control must be used, the series of normally closed

contacts of the external contactors must be connected to terminal 11

of the control unit (figures 3 and 4).
