Page 5: Introduction
Note: This manual refers to an emitter and its receiver, and their cabling as "a System". Banner EZ-SCREEN Type 2 emitters and receivers provide a redundant, microprocessor-controlled, opposed-mode optoelectronic "curtain of light", or "light screen". EZ-SCREEN Type 2 typically is used for point-of-operation safeguarding, and is suited to safeguard a variety of lower-risk machinery. -
Page 6: Appropriate Applications And Limitations
Ensure that all legal requirements have been met and that all technical installation and maintenance instructions contained in this manual are followed. The user has the sole responsibility to ensure that this Banner device is installed and interfaced to the guarded machine by Qualified Persons , in accordance with this manual and applicable safety regulations. -
Page 7: Examples: Appropriate Applications
Failure to follow these instructions could result in serious injury or death. • Use Banner's EZ-SCREEN Type 2 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. -

Page 26: Initial Power-Up
® EZ-SCREEN Type 2 Light Screen 4.3.2 Initial Power-Up 1. Inspect the area near the light screen for reflective surfaces, including work pieces and the guarded machine. Reflective surfaces may cause light beams to reflect around a person in the light screen, preventing the person from being detected and not stopping the machine motion (see Adjacent Reflective Surfaces on p. - Page 27 ® EZ-SCREEN Type 2 Light Screen 1. Verify the sensor mounting. 2. Verify the optimal alignment, adjusting the sensor rotation with the power on: a. Verify that the emitter and the receiver are pointed squarely at each other. Use a straight edge (for example, a level) to determine the direction the sensor is facing.

Page 31: Machine Primary Control Elements And Edm Input
® EZ-SCREEN Type 2 Light Screen Protective Stop (Safety Stop) Circuits A protective stop (safety stop) allows for an orderly cessation of motion for safeguarding purposes, which results in a stop of motion and removal of power from the MPCEs (assuming this does not create additional hazards). A protective stop circuit typically comprises a minimum of two normally open contacts from forced-guided, mechanically linked relays, which are monitored through External Device Monitoring to detect certain failures in order to prevent the loss of the safety function. - Page 32 ® EZ-SCREEN Type 2 Light Screen Connect the receiver’s reset/test wire (pin 8) to the supply voltage (see Generic Wiring to FSDs (manual reset) on p. 34 Generic Wiring — Interface Module (2-Channel EDM, Manual Reset) on p. 35) via the reset switch. The switch should be a normally closed (N.C.) reset switch, or contacts of the Machine Control Test circuit (typically a normally open contact held or energized closed), or the monitoring contacts of the external device(s) being verified.

Results should be recorded and kept in the appropriate place (for example, near the machine, and/or in a technical file). Banner Engineering highly recommends performing the System checkouts as described. However, a qualified person (or team) should evaluate these generic recommendations considering their specific application and determine the appropriate frequency of checkouts. - Page 45 ® EZ-SCREEN Type 2 Light Screen • It is not possible for a person to stand between the defined area and the dangerous parts of the machine, or • Supplemental safeguarding and hard (fixed) guarding, as described by the appropriate safety standards, are in place and functioning properly in any space (between the defined area and any hazard) which is large enough to allow a person to stand undetected by the EZ-SCREEN Type 2.
