Self-diagnosis output
NPN open-collector transistor
・Maximum sink current: 50 mA
・Applied voltage: 30 V DC or less (between self-diagnosis output and 0 V)
・Residual voltage: 1.0 V or less (at 50 mA sink current)
        0.4 V or less (at 16 mA sink current)
Self-diagnosis output:Output operationON under unstable sensing condition (restored automatically after 40 ms approx.), or if the sensing output is short-circuited (restored when short-circuit is rectified).
(For the remote sensitivity adjustment type, it turns ON for 40 ms approx. Also after the remote sensitivity input is received.)
Self-diagnosis output:Short-circuit protection-
Response time0.6 ms or less (0.8 ms or less when the interference prevention function is used)
Operation indicatorRed LED (lights up when the sensing output is ON)
Stability indicatorGreen LED
("RUN" mode: Lights up under stable light received condition or stable dark condition
"SET" mode: At the time of sensitivity setting, blinks twice when the difference between ON and OFF levels is greater than the hysteresis, but blinks 15 times when it is equal to or less than the hysteresis. Also blinks twice after the interference prevention is set
"SET" mode → When "SIF" or "RUN" mode is selected: Blinks from 0 to 5 times according to the sensitivity margin)
Test input (emission halt) functionIncorporated
External synchronization functionIncorporated (Either gate or edge trigger is selectable)
Remote sensitivity setting function-
Remote sensitivity selection function-
Sensitivity shift & limit sensitivity setting functionsShifts the set sensitivity level
Automatic interference prevention functionIncorporated
