This can be broken down into two parts: Ts and Tr where T = Ts + Tr the maximum response time, in seconds, of the EZ-SCREEN emitter/receiver pair (depending on model) the additional distance, in mm, based on intrusion of a hand or object towards the danger zone prior to actuation of a safety device.

  • Page 22: Reducing Or Eliminating Pass-Through Hazards

    This method of safeguarding relies upon the location of the reset switch as well as safe work practices and procedures to prevent an unexpected start or restart of the guarded machine. The EZ-SCREEN 14/30mm Safety Light Screen provides a configurable Manual Start/Restart (Latch Output) function for these applications.

  • Page 23: Reset Switch Location

    ® EZ-SCREEN 14/30 mm Safety Light Screen WARNING: • Perimeter guarding applications • Failure to observe this warning could result in serious injury or death. • Use lockout/tagout procedures per ANSI Z244.1, or use additional safeguarding as described by ANSI B11.19 safety requirements or other applicable standards if a passthrough hazard cannot be eliminated or reduced to an acceptable level of risk.

  • Page 24: Supplemental Safeguarding

    Figure 4. An example of supplemental safeguarding Figure 4 on page 24 shows an example of supplemental safeguarding inside a robotic work cell. The EZ-SCREEN, in conjunction with the hard (fixed) guarding, is the primary safeguard. Supplemental safeguarding (such as a horizontal- mounted safety light screen as an area guard) is required in areas that cannot be viewed from the reset switch (for example, behind the robot and the conveyor).

    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 EZ-SCREEN System. It is good wiring practice, and sometimes may be required by code, to isolate emitter and receiver cables from high-voltage wires, avoid routing cables close to “noisy” wiring, and provide a good connection to earth ground.

  • Page 31: Initial Electrical Connections

    5.7.1 Emitter Wiring Options An EZ-SCREEN emitter with an 8-pin connector can be connected either to its own power supply or to the receiver cable, color-for-color. The color-for-color connection allows the emitter and receiver positions to be interchanged without rewiring.

    5.8.4 Optical Alignment Procedure with Mirrors EZ-SCREEN 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;...

  • Page 35: Reduced Resolution/Floating Blanking

    One or multiple areas within an EZ-SCREEN sensor pair may be blanked out. The minimum number of beams between two blanked areas is one. Any beam other than the sync beam may be blanked. All beams of a fixed blanked area must stay blocked at all times (after the fixed blanking configuration mode has been exited), for the OSSDs to stay ON.

  • Page 36: Trip Test

    5.8.7 Trip Test After optimizing the optical alignment, perform the trip test to verify the detection capability of the EZ-SCREEN System. This test will also verify correct sensor orientation and identify optical short circuits. Once the installation has passed the trip test, the safety outputs may be connected and the commissioning checkout may be performed (initial installations only).

    Depending on the application, the use of FSDs can facilitate controlling voltage and current that differs from the OSSD outputs of the EZ-SCREEN. FSDs can also be used to control an additional number of hazards by creating multiple safety stop circuits.

  • Page 40: Machine Primary Control Elements And Edm Input

    To ensure an accumulation of failures does not compromise the redundant control scheme (cause a failure to danger), a method to verify the normal functioning of MPCEs or other control devices is required. EZ-SCREEN provides a convenient method for this verification: external device monitoring (EDM).

  • Page 41: Auxiliary (Aux.) Output

    Max. For EZ-SCREEN receivers with a date code prior to 0834, the monitoring contacts must open within 200 milliseconds of the OSSD outputs turning ON (a clear condition) and must close within 200 milliseconds of the OSSD outputs turning OFF (a blocked condition) or a lockout will occur.

    74), a faulty switch will be detected if it fails to switch as the guard opens. In this case, the EZ-SCREEN de-energizes its OSSD output and disables its reset function until the input requirements are met (i.e., the faulty switch is replaced). However, when a series of interlocking safety switches is monitored by the EZ-SCREEN, the failure of one switch in the system may be masked or not detected at all .
  • Page 76 EZ-SCREEN considers the failure to be corrected. With the input requirements apparently satisfied, the EZ-SCREEN allows a reset. This system is no longer redundant and, if the second switch fails, may result in an unsafe condition (i.e., the accumulation of faults results in the loss of the safety function).
