    The length of the sensor pair (housing) is dependent on the model, with lengths available from 280 mm to 2380 mm (11 in to 93.7 in). The end to end sensing design of the Protector Series Light Curtain, also known as "no blind zone" and "no dead zone," allows mounting with minimal or no gaps in detection when using EZLSA-MBK-12 center-mount or EZLSA-MBK-16 side-mount brackets.

  • Page 6: Appropriate Applications And Limitations

    • Failure to follow these instructions could result in serious injury or death. • Use Rockford System Protector Series Light Curtain only on machinery that can be stopped immediately after a stop signal is issued at any point in the machine's stroke or cycle, such as part-revolution clutched machines. Under no circumstances may the Protector Series Light Curtain be used on full-revolution clutched machinery or in unsuitable applications.

    (see OSHA 29CFR1910.217, NFPA 79, ANSI B11.19, ISO 12100, IEC 60204-1, IEC 61496-1, or other appropriate standard) If a Protector Series Light Curtain is installed for use as a perimeter guard (where a pass-through hazard may exist, see Reducing or Eliminating Pass-Through Hazards on page 26), the dangerous machine motion can be initiated by normal means only after the safeguarded area is clear of individuals and the Protector Series Light Curtain has been manually reset.

Available on both the receiver and emitter, the output provides a fault signal (lockout = On).
  • Page 18 On cascade models, fixed blanking is available to, in effect, "disable" beams that would otherwise be continually blocked by a stationary object. One or multiple areas within a Protector Series Light Curtain sensor pair may be "blanked out," with a minimum of one beam between two blanked areas.

    Safety Distance (Ds), also called Minimum Distance (S), is the minimum distance required between the defined area and the closest reachable hazard point. The distance is calculated so that when an object or a person is detected (by blocking a sensing beam), the Protector Series Light Curtain sends a stop signal to the machine, causing it to stop by the time the object or person can reach any machine hazard point.

  • Page 26 WARNING: • Use of the Rockford Systems device for Access or Perimeter Guarding — If a Rockford Systems device is installed in an application that results in a pass-through hazard (for example, perimeter guarding), either the Rockford Systems device or the Machine Primary Control Elements (MPCEs) of the guarded machine must cause a Latched response following an interruption of the defined area.
  • Page 27 (mechanical barriers, such as screens or bars), as described by ANSI B11.19 safety requirements or other appropriate standards, must be installed. Access will then be possible only through the defined area of the Protector Series Light Curtain System or through other safeguarding that prevents access to the hazard (see Figure 14 below).
  • Page 28 RESET SWITCH LOCATION The Protector Series Light Curtain has a trip output (auto power-up and automatic reset) that turns the OSSD outputs ON when the defined area is unobstructed (clear). Per application requirements, a latch response requiring a manual reset to a power-up condition or after an interruption has cleared the defined area might be required.

    Emitter and receiver wiring is low voltage; routing the sensor wires alongside power wires, motor/servo wires, or other high voltage wiring may inject noise into the Protector Series Light Curtain System.

    Note: Emitter and receiver power (current) requirements are accounted for. The above values represent additional current draw that must be accounted for because of the load current. Note: Maximum cordset lengths are intended to ensure that adequate power is available to the Protector Series Light Curtain when the supply is operating at +20 V dc.

    2. Eliminate the reflective surfaces as much as possible by relocating, painting, masking, or roughening them. Remaining problem reflections will become apparent during the trip test. 3.

  • Page 42 OPTICAL ALIGNMENT PROCEDURE WITH MIRRORS Protector Series Light Curtain sensors may be used with one or more corner mirrors for guarding more than one side of an area. The MSM-... and SSM-... rear-surface glass mirrors are rated at 85% efficiency. Thus, excess gain and sensing range are reduced when using mirrors; see Use of Corner Mirrors on page 31.

  • Page 70: Response Time For Cascaded Light Screens

    RESPONSE TIME FOR CASCADED LIGHT SCREENS Response time is an important factor in determining a light screen’s safety distance (minimum distance). For cascaded Protector Series Light Curtain systems, that response time is dependent on the number of light screens, the number of beams in the light screens, and their positions in the cascade.

    Protector Series Light Curtain Position #3 The 23 mm resolution, 560 mm Protector Series Light Curtain emitter/receiver pairs = 11.6 + 4 = 15.6 ms each begin with a response time of 11.6 ms. The pair in position #1 (connected directly to the machine control), maintains its 11.6 ms response time.
  • Page 72 • Multiple Emergency Stop Switches • When two or more E-stop switches are connected to the same Protector Series Light Curtain receiver, the contacts of the E-stop switches must be connected together in series.
