Banner AG4 Series Safety Laser Scanner Restart Interlock with Start Interlock (Manual Reset) Automatic Restart Interlock with Start Interlock (Automatic Reset with manual power-up) Automatic Restart Interlock with Automatic Start (Automatic Reset) Automatic Restart Interlock with Start Test (Automatic Reset with test at power-up)In any case, the clearing of the Protected Field (PF), or the reset of a start/restart interlock condition MUST NOTinitiate dangerous machine motion. Machine control circuitry must be designed so that one or more initiation devicesmust be engaged (i.e., a conscious act) to start the machine – in addition to the Scanner turning ON its safety outputs(OSSD1 and OSSD2). See Section 1.12.14.8.1 System Power-UpThe Scanner will power up in one of three ways, depending on the Start/Restart (reset) Interlock configuration (1.12.1)and whether the Start Test is enabled (1.12.2). These options will be limited by the selected application (see Section 3).When power is applied, the Scanner conducts self-tests to detect critical internal faults, determine configuration settings,and prepare for operation, which can take up to 30 seconds (typical). Start Interlock (Manual Power-up): If no faults are detected during the self-test, the Scanner enters Runmode and evaluates the Protective and Warning Fields. If no obstructions are detected, the YellowStart/Restart (Reset) indicator (LED #5 in Figure 1-3) to indicate the Scanner is waiting for a manual reset toturn ON the OSSD outputs. Automatic Start (Automatic Reset): If no faults are detected during the self-test, the Scanner enters Runmode and evaluates the Protective and Warning Fields. If no obstructions are detected, the OSSDs turn ONafter the restart delay time (160 ms to 10160 ms in 40 ms increments) and the two Green indicators (LEDs #1and #3 in Figure 1-3) turn ON. No manual reset operation is required. Start Test (Test at Power-up): If no faults are detected during the self-test, the Scanner waits for theProtective Field to be interrupted by an object equal to or greater than the configured resolution (e.g., a testpiece). Then, after the field is clear the OSSD outputs turn ON. The Protective Field must be clear before thetest is performed, or all obstructions must be removed and then the test can be performed. No manual resetoperation is required.4.8.2 During Run ModeThe Scanner can be configured for two output configurations: Restart Interlock (Manual Reset): When the Protective Field becomes interrupted by an object larger thanthe configured resolution the OSSD outputs turn OFF within the configured response time (see 4.6). If theProtective Field then becomes clear, the LED #1 indicator will be GREEN and the YELLOW Start/Restart(Reset) indicator (LED #5 on Figure 1-3) will indicate the Scanner is waiting for a manual reset to turn ON theOSSD outputs. The OSSD outputs come back ON only when the Protective Field is clear and after a manualreset. This is also known as Latch Output mode. Automatic Restart Interlock (Automatic Reset): When the Protective Field becomes interrupted by anobject larger than the configured resolution the OSSD outputs turn OFF within the configured response time(see 4.6). If the Protective Field then becomes clear, OSSD outputs come back ON. No resets of any kind areneeded. This is also known as Trip Output mode.Internal Faults (Lockouts)If a critical fault(s) is detected, the Scanner enters a lockout condition, the OSSD outputs remain OFF and diagnosticinformation is displayed on the LED display (LED #5 flashes at a 4Hz rate) and is available via the AG4Soft program. Toaccess diagnostic information highlight the ―System Data‖ Operating tab and click on menu bar path System Data >Display the Scanner’s diagnostics list. See Section 5 for resolution of error/fault conditions.4.9 Determining Response TimeThe Scanner's response time is the time needed to switch OFF its OSSD outputs, after an object is detected. Tworesponse time options are provided in the AG4Soft program and must be noted to determine the Safety Distance(Minimum Distance). Either of the two response times can be configured for a time between 80 ms - 640 ms, in 40 msincrements.Buy: www.ValinOnline.com | Phone 844-385-3099 | Email: CustomerService@valin.com |
