the signal strength of the light being received is not sufficient. Possible causes: Sensor
is contaminated, sensor is out of alignment. In the good state: LOW (U
sively contaminated: HIGH (>+U
Health output: The sensor (HTF18L) features a health status notification output ("Q2"
in connection diagram [B], if the health option is selected), which issues a notification if
the signal strength of the light being received is sufficient. Possible causes, if the signal
strength is not sufficient: Sensors are contaminated, sensors are out of alignment, or
cable is damaged. In the good state: HIGH (>+U
the event of cable interruption: LOW (U
Time types: HTF18L with optional On-delay or Off-Delay adjustment: t0 = no time delay,
t1 = time delay when object is detected, t2 = time delay when no object is detected.
The time setting can be selected using the potentiometer according to A.
