4.3 Initial Checkout Procedure
The initial checkout procedure must be performed by a Qualified Person. It must be performed only after configuring the System and
after connecting the emitter and receiver.
The procedure is performed on two occasions:
•
To ensure proper installation when the System is first installed
•
To ensure proper System function whenever any maintenance or modification is performed on the System or on the machinery
that is guarded by the System.
4.3.1 Configuring the System for Initial Checkout
For the initial checkout, the EZ-SCREEN Type 2 System must be checked without power 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, ISO 14118, or the appropriate standard for controlling hazardous energy). The
OSSD 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 and its controls or actuators
•
The machine control circuit or the Safety/Interface Module is not connected to the OSSD outputs at this time (permanent
connections will be made later)
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
