The precautions and statements used throughout this document are indicated by alert symbols and must be followed for the safe use of the EZ-SCREEN LP Limited Function Safety Light Screen. Failure to follow all precautions and alerts may result in unsafe use or operation. The following signal words and alert symbols are defined as follows:...
EZ-SCREEN LP is extensively FMEA (Failure Mode and Effects Analysis) tested to establish an extremely high degree of confidence that, when appropriately installed, no system component will (even if it should fail) cause a failure to danger.
2.2.1 Components An EZ-SCREEN LP “System” refers to a compatible emitter and receiver (equal length and resolution; available separately or in pairs), and cordset(s) for each. It also refers to the emitters and receivers in a cascade, and their cabling. Mounting hardware is included with each emitter and receiver;...
CAUTION: Install System Only on Appropriate Applications Banner EZ-SCREEN LP is for use 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.
2.4 Control Reliability: Redundancy and Self-Checking Redundancy requires that EZ-SCREEN LP circuit components be backed up to the extent that, if the failure of a single component will prevent effective machine stopping action when needed, that component must have a redundant counterpart which will perform the same function.

® EZ-SCREEN LP Limited Function Safety Light Screen Emitter: Description Status Indicator (Red/Green)—Shows whether power is applied or the device is in a lockout condition. 7-segment Diagnostic Display—indicates specific error or configuration conditions. Figure 4. Emitter Receiver: 1-Digit Diagnostic Display—indicates specific error, configuration conditions, or total number of blocked beams.
The distance is calculated so that when an object or a person is detected (by blocking a sensing beam), the EZ-SCREEN LP sends a stop signal to the machine, causing it to stop by the time the object or person can reach any machine hazard point.

(or the hazard removed). 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 LP 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.
S = (K × T ) + C Ds = K × ( Ts + Tr ) + Dpf Mount the EZ-SCREEN LP emitter and receiver so that no part of the defined area will be closer than 528 mm to the closest reachable hazard point on the guarded machine.
Figure 7. An example of supplemental safeguarding Figure 7 on page 13 shows an example of supplemental safeguarding inside a robotic work cell. The EZ-SCREEN LP, 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).
Page 14
Use of Corner Mirrors EZ-SCREEN LP may be used with one or more corner mirrors. Mirrors are not allowed for applications that would allow undetected personnel access into the safeguarded area. The use of glass-surface corner mirrors reduces the maximum specified emitter/receiver separation by approximately 8 percent per mirror, as follows: www.bannerengineering.com - Tel: 763.544.3164...
Page 15
WARNING: Proper Orientation of System Emitters and Receivers EZ-SCREEN LP emitters and receivers must be installed with their corresponding cabled ends pointing in the same direction (for example, both cabled ends facing up). Failure to orient them properly will impair the performance of the EZ-SCREEN LP System and will result in incomplete guarding, and could result in serious bodily injury or death.

Figure 11. Examples of Incorrect Emitter/Receiver Orientation Installation of Multiple Systems Whenever two or more EZ-SCREEN LP emitter and receiver pairs are adjacent to one another, optical crosstalk may take place between the systems. To minimize optical crosstalk, alternate the positions of the emitters and receivers.

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 LP 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”...
All connections are made through the RD or pigtail QD connections. Emitter Cordset EZ-SCREEN LP emitters have an 8-pin cordset, but not all conductors are used. The other wires are in place to allow a parallel connection (color-for-color) to the receiver cable, providing sensor interchangeability (or “swapability”);...
Reference Wiring Diagrams on page 35). 6. Power up the EZ-SCREEN LP System only. 7. Verify that the input power is present to both the emitter and the receiver. At least one indicator on both the emitter and the receiver should be On and the start-up sequence should cycle.
4.3.4 Optical Alignment Procedure with Mirrors EZ-SCREEN LP 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;...
After optimizing the optical alignment and configuring fixed blanking and/or reduced resolution (if applicable), perform the trip test to verify the detection capability of the EZ-SCREEN LP System. This test also verifies correct sensor orientation, identifies optical short circuits, and verifies the expected resolution for applications using reduced resolution. After the installation has passed the trip test, the safety outputs may be connected and the commissioning checkout may be performed (initial installations only).
WARNING: If Trip Test Indicates a Problem If the EZ-SCREEN LP System does not respond properly to the trip test, do not attempt to use the System. If this occurs, the System cannot be relied on to stop dangerous machine motion when a person or object enters the defined area.
Depending on the application, the use of FSDs can facilitate controlling voltage and current that differs from the OSSD outputs of the EZ-SCREEN LP. FSDs can also be used to control an additional number of hazards by creating multiple safety stop circuits.
EZ-SCREEN LP is ready for testing in combination with the guarded machine. The operation of the EZ-SCREEN LP with the guarded machine must be verified before the combined System and machine may be put into service. To do this, a Qualified Person must perform the Commissioning Checkout Procedure.
To prepare the System for this checkout: 1. Examine the guarded machine to verify that it is of a type and design compatible with the EZ-SCREEN LP System. See Examples: Inappropriate Applications on page 8 for a list of misapplications.
16. Remove electrical power to the EZ-SCREEN LP. Both OSSD outputs should immediately turn Off, and the machine must not be capable of starting until power is re-applied to the EZ-SCREEN LP.

No manual reset operation is required. 5.3.2 Run Mode If any beams become blocked while the EZ-SCREEN LP is running, the receiver outputs turn Off within the stated EZ- SCREEN LP response time (see GUID-92E22EE9-735B-4C44-8FFC-2C2184930F37). If all the beams then become clear, the receiver outputs come back On.
6.1 Lockout Conditions A Lockout condition causes all of the EZ-SCREEN LP 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 Receiver Error Codes and Emitter Error Codes) or the Diagnostic Error Code label supplied in the documentation pack).

6.3 Electrical and Optical Noise The EZ-SCREEN LP is designed and manufactured to be highly resistant to electrical and optical noise and to operate reliably in industrial settings. However, serious electrical and/or optical noise may cause a random Trip condition. In extreme electrical noise cases, a Lockout is possible.
2. Cover the lens of the BT-1 with electrical tape to block optical light from entering the receiver lens. 3. Press the RCV button on the BT-1 and position the Beam Tracker on the wires going to the EZ-SCREEN LP or any other nearby wires.
