5.4 Normal Operation

5.4.1 System Power-Up

Apply power and verify that the Status Blocked LED is OFF, and Status Clear LED is ON Green.
Trip Output Systems: When power is applied, each sensor will conduct self-tests to detect critical internal faults and
prepare for operation. If either sensor detects a critical fault, scanning ceases, the receiver outputs remain Off and
diagnostic information is displayed via the LEDs; see
are detected, the receiver will look for an optical sync pattern from the emitter. If the receiver is aligned and receiving 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.
Latch Output Systems: When power is applied, each sensor will conduct self-tests to detect critical internal faults and
prepare for operation. If either sensor detects a critical fault, scanning ceases, the receiver outputs remain Off and
diagnostic information is displayed via the LEDs; see
are detected, the receiver will look for an optical sync pattern from the emitter. If the receiver is aligned and receiving the
proper sync pattern, it begins scanning to determine the blocked or clear status of each beam. When all beams are
aligned, the Yellow Alignment indicators will flash to indicate the System is waiting for a manual reset. After a valid manual
reset, the System enters Run mode and begins scanning.

5.4.2 Run Mode

Trip Output Systems: If any beams become blocked while the System is running, the receiver outputs turn Off within the
stated System response time (see
become clear, the receiver outputs come back ON. No resets of any kind are needed. All required machine control resets
are provided by the machine control circuit.
Latch Output Systems: If any beams become blocked while the System is running, the receiver outputs turn Off within the
stated System response time (see
become clear, the receiver Clear Status indicator be ON Green and the Alignment indicators will flash, indicating the
System is waiting for a manual latch 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
diagnostic information is displayed via the LEDs. See
of error/fault conditions.

5.4.3 Manual Reset Procedure

Open the reset switch for at least 1/4 second, then close it.

5.5 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
should be posted on or near the machine.
Whenever changes are made to the System (either a new configuration of the EZ-SCREEN Type 2 System or changes
to the machine), the Commissioning Checkout should be performed (see
NOTE: Verify Proper Operation
The EZ-SCREEN Type 2 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
in an increased risk of harm.
Before the System is put back into service, verify that the EZ-SCREEN Type 2 System and the guarded
machine perform exactly as outlined in the checkout procedures and any problem(s) are found and
corrected.
