Banner EZ-SCREEN­ Safety Light Curtain Systems - Manual (Page 29)

Configuring the System for Initial Checkout
For the initial checkout, the EZ-SCREEN Type 2 System must be checked without power being available to the guarded machine. Final
interface connections to the guarded machine cannot take place until the light screen system has been checked out. This may require
lockout/tagout procedures (refer to OSHA1910.147, ANSI Z244-1, or the appropriate standard for controlling hazardous energy). These
connections will be made after the initial checkout procedure has been successfully completed.
Verify that:
• Power has been removed from (or is not available to) the guarded machine, its controls or actuators; and
• The machine control circuit or the Interface Module is not connected to the OSSD outputs at this time (permanent connections will be
made later).
Initial Power-Up
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.
Eliminate the reflective surfaces as possible by relocating them, painting, masking or roughening them. Remaining problem reflections
will become apparent during the trip test.
1. Verify that power is removed from the EZ-SCREEN Type 2 System and from the guarded machine and that the OSSD safety
outputs are not connected. Remove all obstructions from the light screen.
2. Leaving power to the guarded machine OFF, make power and earth ground connections on both the emitter and receiver cables
and then power up the EZ-SCREEN Type 2 System (only).
3. Verify that input power is present to both emitter and receiver. At least one indicator on both emitter and receiver should be ON and
the start-up sequence should cycle.
