5.4 Normal Operation5.4.1 System Power-UpApply 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 andprepare for operation. If either sensor detects a critical fault, scanning ceases, the receiver outputs remain Off anddiagnostic information is displayed via the LEDs; see Troubleshooting and Lockout Conditions on page 40). If no faultsare detected, the receiver will look for an optical sync pattern from the emitter. If the receiver is aligned and receiving theproper sync pattern, it enters Run mode and begins scanning to determine the blocked or clear status of each beam. Nomanual reset operation is required.Latch Output Systems: When power is applied, each sensor will conduct self-tests to detect critical internal faults andprepare for operation. If either sensor detects a critical fault, scanning ceases, the receiver outputs remain Off anddiagnostic information is displayed via the LEDs; see Troubleshooting and Lockout Conditions on page 40). If no faultsare detected, the receiver will look for an optical sync pattern from the emitter. If the receiver is aligned and receiving theproper sync pattern, it begins scanning to determine the blocked or clear status of each beam. When all beams arealigned, the Yellow Alignment indicators will flash to indicate the System is waiting for a manual reset. After a valid manualreset, the System enters Run mode and begins scanning.5.4.2 Run ModeTrip Output Systems: If any beams become blocked while the System is running, the receiver outputs turn Off within thestated System response time (see EZ-SCREEN Type 2 Models With Response Times on page 12). When all the beamsbecome clear, the receiver outputs come back ON. No resets of any kind are needed. All required machine control resetsare 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 thestated System response time (see EZ-SCREEN Type 2 Models With Response Times on page 12). When all the beamsbecome clear, the receiver Clear Status indicator be ON Green and the Alignment indicators will flash, indicating theSystem is waiting for a manual latch reset. When a valid reset signal is received and all beams remain clear, the receiveroutputs turn ON.Internal Faults (Lockouts): If either sensor detects a critical fault, scanning ceases, the receiver outputs turn Off anddiagnostic information is displayed via the LEDs. See Troubleshooting and Lockout Conditions on page 40 for resolutionof error/fault conditions.5.4.3 Manual Reset ProcedureOpen the reset switch for at least 1/4 second, then close it.5.5 Periodic Checkout RequirementsTo 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 checkoutmay 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 checkoutmust be performed by a Qualified Person (see Checkout Procedure Schedule on page 44). A copy of these test resultsshould 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 changesto the machine), the Commissioning Checkout should be performed (see Commissioning Checkout on page 33).NOTE: Verify Proper OperationThe EZ-SCREEN Type 2 can operate as it is designed only if it and the guarded machine are operatingproperly, both separately and together. It is the user’s responsibility to verify this, on a regular basis,as instructed in Checkout Procedure Schedule on page 44 . Failure to correct such problems can resultin an increased risk of harm.Before the System is put back into service, verify that the EZ-SCREEN Type 2 System and the guardedmachine perform exactly as outlined in the checkout procedures and any problem(s) are found andcorrected.EZ-SCREEN® Type 2 Light ScreenPhone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com
