    CHAPTER 1 GENERAL INFORMATION GENERAL DESCRIPTION The safety light curtains are optoelectronic multi-beam devices that are used to protect working areas that, in presence of machines, robots, and automatic systems in general, can become dangerous for operators that can get in touch, even accidentally, with mov- ing parts.
  • Page 10 As the required knowledge may not be completely included in this manual, we suggest the customer to contact Datasensing Technical Service for any necessary information relative to the functioning of the light curtains and the safety rules that regulate the correct installation.

  • Page 17: Height Of The Detection Zone

    HOW TO CHOOSE THE DEVICE Height of the detection zone The controlled height is the height protected by the safety light curtain. In SH4-14/30 Protected Height is equal to ESPE total length: no dead zone is present. In SH4-2/3/4, first beam center is positioned at 130 mm from light curtain bottom, pro- tected height is defined as the distance between uppermost and lowermost beam centreline.

  • Page 18: Minimum Installation Distance

    When devices with > 40 mm resolution are used, the height of the top beam has to be ≥ 900 mm (H2) from machine supporting base while the height of the bottom beam has to be ≤ 300 mm (H1). SH4 ADVANCED...

  • Page 19: Practical Examples

    HOW TO CHOOSE THE DEVICE If the safety light curtain must be mounted in a horizontal position (see figure below) the distance between the dangerous area and the most distant optical beam must be equal to the value calculated using the following formula: S = 1600 mm/s (t1 + t2) + 1200 - 0.4 H where: •...

  • Page 20: Typical Applications

    The safety light curtain can be used in most bending operations thanks to its easy installation and compact dimensions. As well as offering excellent reliability, SH4 ensures increased plant productivity as it reduces the dead times necessary for machine accessing, adjustment and maintenance. SH4 ADVANCED...

  • Page 21: Example 3: Paper Cutting Machines

    TYPICAL APPLICATIONS Example 3: Paper cutting machines These machines typically cut paper to a specific size for newspapers or special applica- tions. The operator must be protected against abrasion or cuts by cutter blades. Solution: SH4 30mm safety light curtain is especially suitable for this kind of applica- tion, which require the installation of the device directly on the machine.

  • Page 22: Safety Information

    • The RESET/RESTART button must be located outside the dangerous zone because the operator must check the dangerous zone during Reset/Restart operations. NOTE: Please carefully read the instructions for the correct functioning before powering the light curtain on. SH4 ADVANCED...

  • Page 23: General Information On Device Positioning

    GENERAL INFORMATION ON DEVICE POSITIONING GENERAL INFORMATION ON DEVICE POSITIONING The safety light curtain should be carefully positioned in order to provide the necessary protection. Access to the dangerous area must only be possible by passing through the protecting safety light beams. CAUTION: The figure below shows some examples of possible access to the machine from the top and the bottom sides.

Up to three SH4 unit can be connected in series as a cascade system. Cascading is when two or more light curtains are connected to each other, resulting in one system that functions as a single light curtains.

    CONNECTION CONNECTION In order to connect SH4 units in a cascade system, follow the steps below: 1. Connect the M12-5 poles female connector of the MASTER unit to the M12-5 poles male connector of following slave unit. 2. Same way a LAST SLAVE can be connected to the MID SLAVE. NOTE: When the distance between units doesn't allow a direct connection an optional M12 male to M12 female 5 pole cable may be used up to 10 m cable length.
