5.3 Normal Operation

5.3.1 System Power-Up

When power is applied, each sensor conducts self-tests to detect critical internal faults, determine configuration settings,
and prepare the EZ-SCREEN LP for operation. If either sensor detects a critical fault, scanning ceases, the receiver outputs
remain Off and diagnostic information displays on the sensor's Diagnostic Display. If no faults are detected, the EZ-
SCREEN LP 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 enters Run mode and begins scanning to determine the
blocked or clear status of each beam. 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. No resets are needed. All required machine control resets are provided by the machine
control circuit.
Internal Faults (Lockouts): If either sensor detects a critical fault, scanning ceases, the receiver outputs turn Off and
diagnostic information displays on the sensor's Diagnostic Display. See
error/fault conditions.

5.4 Periodic Checkout Requirements

To ensure continued reliable operation, the System must be checked out periodically.
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
posted on or near the machine.
Whenever changes are made to the System (either a new configuration of the EZ-SCREEN LP System or changes to
the machine), perform the Commissioning Checkout.
NOTE: Verify Proper Operation
The EZ-SCREEN LP 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
increased risk of harm.
Before the System is put back into service, verify that the EZ-SCREEN LP System and the guarded
machine perform exactly as outlined in the checkout procedures and any problem(s) are found and
corrected.
8 f beam 1 is blocked, Zone indicators 2–8 will be Off, because beam 1 provides the synchronization signal for all the beams.
