Note: If both the emitter and its corresponding receiver do not have the same scan code setting, the receiver indicates
that Beam 1 is blocked (the Diagnostic display indicating "C" "H" "1" as shown above). This can occur if the Scan
Code input is not wired the same for both sensors or if the EDM circuit has not been re-wired for one-channel
monitoring in retrofit installations of two-channel EDM applications, see warning in
on page 42.

7.3 Normal Operation

7.3.1 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 LS Basic 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 LS Basic 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.
7.3.2 Run Mode
If any beams become blocked while the EZ-SCREEN LS Basic is running, the receiver outputs turn Off within the stated EZ-
SCREEN LS Basic response time (see
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.

7.4 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
on or near the machine.
Whenever changes are made to the System (either a new configuration of the EZ-SCREEN LS Basic System or changes to
the machine), perform the Commissioning Checkout.
8 If beam 1 is blocked, Alignment indicators will be Off, because beam 1 provides the synchronization signal for all the beams.
