EZ-SCREEN LP Instruction Manual Overview Overview 1. Overview 1.1 Introduction Banner EZ-SCREEN LP emitters and receivers provide a redundant, microprocessor-controlled, opposed-mode optoelectronic “curtain of light,” or “safety light screen.” EZ-SCREEN LP typically is used for point-of-operation safeguarding, and is suited to safeguard a variety of machinery. Emitters have a row of synchronized modulated infrared (invisible) light-emitting diodes (LEDs) in a compact metal housing.
Overview 1.2 Applications and Limitations The Banner EZ-SCREEN LP is intended for point-of-operation machine guarding applications and other safeguarding applications. It is the user’s responsibility to verify whether the safeguarding is appropriate for the application and is installed, as instructed by this manual, by a Qualified Person. Before installing the EZ-SCREEN LP, read this manual in its entirety, paying particular attention to this section and all of Section 3.
EZ-SCREEN LP Instruction Manual 1.4 Operating Features The Banner EZ-SCREEN LP models described by this manual feature several standard selectable functions: • Reduced Resolution (Floating Blanking), • Trip or Latch Output, • External Device Monitoring (EDM), • Auxiliary Output — OSSD Follow or Fault, • Scan Code setting, • Fixed Blanking (including Remote Teach), • Emitter Test and Fault functions, • Inverted Display, and • Cascading (available on SLPC.. models).
EZ-SCREEN LP Instruction Manual Overview 1.4.6 Reduced Resolution (Floating Blanking) Reduced Resolution increases the minimum diameter of an object that the light screen can reliably detect anywhere within its defined area. Reduced Resolution is generally used to allow one or more objects (usually workpiece materials) to move anywhere through the defined area, without tripping the OSSD safety outputs.
EZ-SCREEN LP Instruction Manual 1.4.8 Manual Resets and Lockout Conditions Reset Routine The EZ-SCREEN LP requires a manual reset to clear a PowerUp Lockout or Latch condition, and after correcting the cause of a Lockout condition. This function is designed to provide a “monitored manual reset” (i.e., open-closed-open action), such that a shorted or tied-down button cannot cause a reset. When a key-operated switch is used, this is typically called a key reset.

EZ-SCREEN LP Instruction Manual Installation and Overview Alignment 3. Installation and Alignment Before installing the EZ-SCREEN LP, read Section 1.2 and Section 3 of this manual in their entirety. The 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 LP Instruction Manual Installation Overview and Alignment WARNING . . . Determine Correct Stop Time Stop time (Ts) must include the response time of all devices or controls that react to stop the machine. If all devices are not included, the calculated safety/minimum distance (Ds or S) will be too short. This can lead to serious bodily injury or death. Be sure to include the stop time of all relevant devices and controls in your calculations.
EZ-SCREEN LP Instruction Manual 3.1.2 Pass-Through Hazards A “pass-through hazard” is associated with applications where personnel may pass through a safeguard (which issues a stop command to remove the hazard), and then continues into the guarded area, such as in perimeter guarding. Subsequently, their presence is no longer detected, and the related danger becomes the unexpected start or restart of the machine while personnel are within the guarded area.
EZ-SCREEN LP Instruction Manual Installation Overview and Alignment The mechanical barriers used for this purpose are typically called “hard guarding”; there must be no gaps between the hard guarding and the defined area. Any openings in the hard guarding must comply with the safe opening requirements of ANSI B11 or other appropriate standard. WARNING . . .
EZ-SCREEN LP Instruction Manual Installation and Overview Alignment 3.1.6 Adjacent Reflective Surfaces A reflective surface adjacent to the defined area may deflect one or more beams around an object in the defined area. In the worst case, an “optical short circuit” may occur, allowing an object to pass undetected through the defined area (see Figure 3-6). This reflective surface may result from shiny surfaces or glossy paint on the machine, the workpiece, the work surface, the floor or the walls.

EZ-SCREEN LP Instruction Manual Installation Overview and Alignment 3.3 Initial Electrical Connections Lockout/tagout procedures may be required (refer to OSHA 29CFR1910.147, ANSI Z244-1, or the appropriate standard for controlling hazardous energy). Following relevant electrical standards and wiring codes, such as the NEC, NFPA79 or IEC60204-1, always connect earth ground (green/yellow wire, see Figures 3-23 through 3-26). Do not operate the EZ-SCREEN LP System without an earth ground connection.
EZ-SCREEN LP Instruction Manual 3.4 Light Screen Initial Checkout The initial checkout procedure must be performed by a Qualified Person (see Section 4.1).

EZ-SCREEN LP Instruction Manual Installation Overview and Alignment 3.5.1 OSSD Output Connections Both the output signal switching device (OSSD) outputs must be connected to the machine control so that the machine’s safety-related control system interrupts the circuit or power to the machine primary control element(s) (MPCE), resulting in a non-hazardous condition. Final switching devices (FSDs) typically accomplish this when the OSSDs go to an OFF state. See Figure 3-24.
EZ-SCREEN LP Instruction Manual Installation and Overview Alignment 3.5.3 Machine Primary Control Elements and EDM Inputs A machine primary control element (MPCE) is an “electrically powered element that directly controls the normal operation of a machine in such a way that it is the last element (in time) to function when machine operation is to be initiated or arrested” (per IEC61496-1). Examples include motor contactors, clutch/ brakes, valves, and solenoids.

EZ-SCREEN LP Instruction Manual Scan code is used to allow operation of multiple pairs of emitters and receivers in close proximity (see Sections 3.1.8 and 1.4.4). Scan code may be set to 1 or 2, via DIP switch (see Table 4-1). The scan code setting for each emitter must agree with its corresponding receiver. Scan code settings may be changed while in Run mode without causing a Lockout. Trip or latch output operation is selected on two DIP switches in the receiver configuration port; see Figure 4-1.

Troubleshooting and Maintenance Overview EZ-SCREEN LP Instruction Manual 5. Troubleshooting and Maintenance 5.1 Troubleshooting Lockout Conditions Evaluate status indicators per Section 4.4. See Section 5.2 for Test mode indication. A Lockout condition causes all of the EZ-SCREEN LP’s OSSD outputs to turn or remain OFF, sending a stop signal to the guarded machine. Each sensor provides diagnostic error codes to assist in the identification of the cause(s) of lockouts (see Sections 5.1.1 and 5.1.

EZ-SCREEN LP Instruction Manual Cascadeable EZ-SCREEN Overview E-Stop Switch Requirements (Positive-Opening) As shown in Figure 7-8, the E-stop switch must provide two contact pairs, which are closed when the switch is in the “armed” position. Once activated, the E-stop switch must open its contacts and return to the closed-contact position only after deliberate action (such as twisting, pulling, or unlocking). The switch should be a “positive-opening type,” as described by IEC947-5-1.

EZ-SCREEN LP Instruction Manual FMEA (Failure Mode and Effects Analysis): A testing procedure by which potential failure modes in a system are analyzed to determine their results or effects on the system. Component failure modes that produce either no effect or a Lockout condition are permitted; failures which cause an unsafe condition (a failure to danger) are not. Banner safety products are extensively FMEA tested. Guarded Machine: The machine whose point of operation is guarded by the safety system.
Glossary Overview PSDI (Presence-Sensing Device Initiation): An application in which a presence-sensing device is used to actually start the cycle of a machine. In a typical situation, an operator manually positions a part in the machine for the operation. When the operator moves out of the danger area, the presencesensing device starts the machine (no start switch is used). The machine cycle runs to completion, and the operator can then insert a new part and start another cycle.
