SCREEN SLS automatically enters Alignment mode, and the receiver looks for an optical sync pattern from the emitter. If the
receiver is aligned and receives the proper sync pattern, it begins scanning to determine the blocked or clear status of each
beam. When all beams are aligned, the Yellow Reset indicator double-flashes to indicate the EZ-SCREEN SLS is waiting for
a manual reset. After a valid manual reset, the EZ-SCREEN SLS enters Run mode and continues scanning.
Trip Output Configuration —If any beams become blocked while the EZ-SCREEN SLS is running with Trip Output selected,
the receiver outputs turn OFF within the stated EZ-SCREEN SLS response time (see "Components" on page 17 ). If all the
beams then become clear, the receiver outputs come back ON. No resets of any kind are needed. All required machine con-
trol resets are provided by the machine control circuit.
Latch Output Configuration —If any beams become blocked while the EZ-SCREEN SLS is running with Latch Output select-
ed, the receiver outputs turn OFF within the stated EZ-SCREEN SLS response time (see "Components" on page 17 ). If all
the beams then become clear, the receiver Zone indicators will all be Green and the Reset indicator will single-flash, indicat-
ing the
EZ-SCREEN SLS is waiting for a manual latch reset. In Latch Output operation, the outputs come back ON only when
all beams are clear and after a manual reset. The EZ-SCREEN SLS will wait for a manual reset; when a valid reset signal is
received and all beams remain clear, the receiver outputs turn ON.
Internal Faults (Lockouts) —If either sensor detects a critical fault, scanning ceases, the receiver outputs turn OFF and diag-
nostic information is displayed through the sensor’s front window. See "Troubleshooting" on page 85 for resolution of error/
fault conditions.
To ensure continued reliable operation, the System must be checked out periodically. Banner Engineering highly recom-
mends performing the System checkouts as described below. However, a Qualified Person should evaluate these recom-
mendations, based on the specific application and the results of a machine risk assessment, to determine the appropriate
content and frequency of checkouts.
At every shift change, power-up, and machine setup change, the Daily Checkout should be performed; this checkout may be
performed by a Designated or Qualified Person.
Semi-annually, the System and its interface to the guarded machine should be thoroughly checked out; this checkout must be
performed by a Qualified Person (see " Checkout Procedures " on page 65 ). A copy of these test results should be posted on
or near the machine.
Whenever changes are made to the System (either a new configuration of the EZ-SCREEN SLS System or changes to the
machine), perform the Commissioning Checkout (see " Commissioning Checkout " on page 66 ).
Verify Proper Operation The EZ-SCREEN SLS can operate as it is designed only if it and the guarded machine are operating
properly, both separately and together. It is the user’s responsibility to verify this, on a regular basis, as instructed in " Check-
out Procedures" on page 65 . Failure to correct such problems can result in an increased risk of harm. Before the System is
put back into service, verify that the EZ-SCREEN SLS System and the guarded machine perform exactly as outlined in the
checkout procedures and any problem(s) are found and corrected.
