EZ-SCREEN Grid System Introduction Instruction Manual 1. Introduction — Overview 1.1 System Description The Banner EZ-SCREEN™ Grid System is an optically synchronized, microprocessor-controlled, opposed-mode optoelectronic “light grid.” This economical two-part system consists of an emitter and receiver. The system requires no external controller or sync wire between the emitter and receiver; the microprocessors are located within the receiver.
EZ-SCREEN Grid System Introduction Instruction Manual Five sensor configurations are available, with two, three or four beams; emitters have short-range and long-range versions. (Receivers are the same for both long-range and short-range operation.) Beam spacing ranges from 300 mm to 584 mm (12" to 23"), depending on the model. The configuration (the overall length and beam spacing) required for an application is determined by the application and the safety standards being followed. Models SG..
EZ-SCREEN Grid System Introduction Instruction Manual 1.2 Applications and Limitations The Banner EZ-SCREEN Grid System is designed for use in access-guarding and perimeter-guarding applications. It is designed to be mounted vertically, in order to detect a body or torso (rather than a hand or an arm) as a person enters a hazardous area. It is not intended nor designed for hand or finger detection in point-of-operation guarding or for area-guarding applications.
EZ-SCREEN Grid System Introduction Instruction Manual ! WARNING . . . Use of Trip Output Hard Guarding Hard Guarding Application of power to the EZ-SCREEN Grid System MUST NOT initiate dangerous machine motion. Machine control circuitry must be designed so that one or more initiation devices must be engaged (i.e. a conscious act) to start the machine in addition to the EZSCREEN Grid System going into RUN mode.
EZ-SCREEN Grid System Introduction Instruction Manual 1.3 Control Reliability In addition to physical location requirements, safety standards require a safety system such as the EZ-SCREEN Grid to fulfill some internal requirements. For example, for an optical safety system to be used in a Safety Category 4 application (per ISO 13849-1/EN954-1), it must be third-party certified to the type 4 requirements of IEC 61496-1 and -2.
EZ-SCREEN Grid System Introduction Instruction Manual If trip output is selected, the OSSD outputs will turn ON after power is applied, and the receiver passes its internal self-test/synchronization and recognizes that all beams are clear. The trip output will also automatically reset after all interruptions of one or more beams are cleared. If latch output is selected, the EZ-SCREEN requires a manual reset for the OSSD outputs to turn ON, after power is applied and all beams are clear (see Section 4.2.

EZ-SCREEN Grid Installation and Alignment Instruction Manual 3. Installation and Alignment ! Read Section 3 in its entirety before installing the Banner EZ-SCREEN Grid System. The Banner EZ-SCREEN Grid System’s ability to perform its safety guarding function depends upon the appropriateness of the application and upon its proper mechanical and electrical installation and interfacing to the guarded machine.
EZ-SCREEN Grid Installation and Alignment Instruction Manual 3.2 Security Protocol Certain procedures for installing, maintaining and operating the EZ-SCREEN Grid system must be performed by either Designated Persons or Qualified Persons. A Designated Person is identified and designated in writing, by the employer, as being appropriately trained and qualified to perform the specified checkout procedures on the EZ-SCREEN Grid system. A machine operator so designated may be a Designated Person.
EZ-SCREEN Grid Installation and Alignment Instruction Manual 3.3 Mechanical Installation Considerations Two factors have the greatest influence on the mechanical installation of the EZ-SCREEN System: • The required separation (safety) distance, and • The presence of hard guarding. 3.3.1 Minimum Separation Distance (Ds) Minimum Separation (Safety) Distance (Ds) is the minimum distance required between the light grid and the closest reachable hazard point.
EZ-SCREEN Grid Installation and Alignment Instruction Manual Notice Regarding MPCEs Each of the two Machine Primary Control Elements (MPCE 1 and MPCE2) must be capable of immediately stopping the dangerous machine motion, irrespective of the state of the other. These two channels of machine control need not be identical, but the stop time performance of the machine (Ts, used to calculate the separation distance) must take into account the slower of the two channels.
EZ-SCREEN Grid Installation and Alignment U.S. Applications: Using the formula, Ds = K x (Ts + Tr) + Dpf separation distance for a model SG..3-533 EZ-SCREEN Grid System (42" protected height with 3 beams, 21" apart) is calculated (per ANSI/RIA R15.06): K = 63"/second Ts = 0.32 (0.250 second is specified by the machine manufacturer; plus 20% safety factor; plus 20 ms for interface module IM-T-9A response) Instruction Manual ! CAUTION . . .
EZ-SCREEN Grid Installation and Alignment Instruction Manual ! WARNING . . . The Machine Hazard Must Be Accessible Only Through the Light Grid Mechanical barriers (“hard guarding”) or supplemental safeguarding, as described by the ANSI B11 series of safety requirements or other appropriate standards, must be installed wherever needed to prevent any person from: 3.3.
EZ-SCREEN Grid Installation and Alignment Instruction Manual 3.3.3 Emitter/Receiver Orientation The emitter and receiver must be mounted vertically, and parallel to each other, with their displays either both at the top or both at the bottom. Otherwise dangerous voids in the light grid could allow objects or personnel to pass undetected through the grid (see Figure 3-5).
EZ-SCREEN Grid Installation and Alignment Instruction Manual ! WARNING . . . Avoid Installation Near Reflective Surfaces Avoid mounting the light grid near any reflective surfaces. A reflective surface located nearby may reflect light around an object or person within the light grid, preventing its detection by the light grid. This possibility is detected during the trip test. Failure to prevent reflection problems will result in incomplete guarding; serious bodily injury or death could result. 3.3.
EZ-SCREEN Grid Installation and Alignment Instruction Manual 3.3.5 Use of Corner Mirrors EZ-SCREEN Grid Systems may be used with one or more vertical corner mirrors in perimeter-guarding applications (see Section 2.2 for availability). The use of corner mirrors reduces the maximum specified emitter/receiver separation by approximately 8 percent per mirror (see Section 3.4). Mirrors are not allowed for applications that would allow personnel undetected access into the safeguarded area.
EZ-SCREEN Grid Installation and Alignment Instruction Manual 3.3.6 Avoiding Electrical and Optical Noise The EZ-SCREEN System is designed and manufactured to be highly resistant to electrical and optical noise and to operate reliably in industrial settings. However, extreme electrical and/or optical noise may cause a random trip or latch condition. In very extreme cases, a lockout is possible. Care should be taken to avoid sources of interference when planning the mounting location.
EZ-SCREEN Grid Installation and Alignment Instruction Manual 3.4 Mechanical Mounting Procedure Short-range emitters and receivers may be mounted up to 20 m (65') apart. Long-range emitters and receivers may be mounted between 15 m (49') and 70 m (230') apart. If Banner SSM corner mirrors are used, the total range decreases by approximately 8 percent per mirror, as follows: Corner Mirrors Short-Range Systems Long-Range Systems 1 18.3 m (60') total 64 m (210') total 2 16.8 m (55') total 59.
EZ-SCREEN Grid Installation and Alignment Instruction Manual Mounting the Sensors All system components (emitter, receiver, and corner mirrors, if used), must be parallel to each other and perpendicular to the floor. If the floor is level, the components may be checked for plumb, using a level, for example. If the floor is sloped, alignment is more complex, because the floor-to-bottom-beam measurement must remain constant, or not exceed the maximum height above the floor.
EZ-SCREEN Grid Installation and Alignment Instruction Manual Installations With Corner Mirrors If corner mirrors are used in the application, measure and position them as for the sensors. Refer to the data sheet packed with the mirrors for specific installation instructions. ! WARNING . . .
EZ-SCREEN Grid Installation and Alignment Instruction Manual 4) Route the wires or cabling through the bracket (if necessary) and the wiring chamber end cap. Remove outer cable insulation as necessary (approximately 1" to 2") and strip the individual wire insulation approximately 7 mm (0.25"); make connections to terminals as indicated in Figure 3-11. Torque the terminal screws to 0.22 to 0.25 N m (1.9 to 2.2 in. lbs.) recommended torque.
EZ-SCREEN Grid Installation and Alignment Instruction Manual 3.6 Light Grid Initial Checkout and Optical Alignment Procedure Verifying System Operation The initial checkout procedure must be performed by a Qualified Person (see WARNING, page 17). It must be performed only after configuring the System and after connecting the emitter and receiver per Section 3.5.
EZ-SCREEN Grid Installation and Alignment Instruction Manual Optical Alignment Procedure After the emitter and receiver are mechanically aligned (perpendicular to the floor along the path of the beams, and plumb in all possible directions), optically align them, first using the LAT-1, if desired, and finally using the receiver Beam Status indicators. Beam 1 location mark is visible in center of hole Figure 3-12.
EZ-SCREEN Grid Installation and Alignment Instruction Manual 1) Attach the battery-powered LAT-1 to the housing of the emitter over the location of beam 1 (closest to the display), using the EZ-SCREEN bracket clip included with the tool. A dot on the sensor housing next to the lens window indicates the beam’s location. Align the hole on the LAT-1 over the beam 1 marking (see Figure 3-12).
EZ-SCREEN Grid Installation and Alignment Instruction Manual ! WARNING . . . Interfacing of both OSSDs Both of the OSSD (Output Signal Switching Device) outputs must be connected to the machine control so that the machine’s safety-related control system interrupts the circuit to the machine primary control element(s), resulting in a nonhazardous condition.
EZ-SCREEN Grid Installation and Alignment Instruction Manual The interfacing of the Safety Stop Circuits must be accomplished so that the safety function can not be suspended, overridden, or defeated, unless accomplished in a manner at the same or greater degree of safety as the machine’s safety related control system that includes the EZ-SCREEN.
EZ-SCREEN Grid Installation and Alignment Instruction Manual NOTE: MPCE Monitoring and Control Reliability In the U.S., Control Reliability requires that a single failure does not prevent a normal stop from occurring, or issues an immediate stop command, and the next cycle is prevented from occurring until the fault is corrected.
EZ-SCREEN Grid Installation and Alignment Instruction Manual 3.7.4 Remote Test Input A pair of terminals is provided on the emitter terminal block (labeled TEST1 and TEST2) for the connection of an external remote test switch (typically a normally open contact held closed). This remote test input may be useful for EZ-SCREEN Grid System setup and checkout procedures. Opening this switch “turns OFF” the emitter, simulating an interruption of the light beams; all OSSD outputs will turn OFF.
