5.4 Normal Operation

5.4.1 System Power-Up

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 Troubleshooting and Lockout Conditions
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 Troubleshooting and Lockout Conditions
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 EZ-SCREEN Type 2 Models With Response Times
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 EZ-SCREEN Type 2 Models With Response Times
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

5.4.3 Manual Reset Procedure

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