A warning can be output via the Q1 and Q2 digital outputs if the signal level drops
below a certain value. This value can either be specified as a number value or deter‐
mined by the
Teach-in
function. When the
Teach-in
function is used, the threshold value
for outputting the warning is calculated by reducing the measured signal level value by
about 12%. Then the warning will not be output until the signal level is about 12% lower
than it was at the time it was taught in.
The level warning threshold or signal level switching point can be set manually using a
signal level within the value range of 0 to 5,000. The signal level is a sensor-specific,
unitless value. We recommend configuring the setting using application-specific test
measurements.
In automated mode, the device automatically regulates the reception level to around
1,000. In the case of very critical object surfaces, an abrupt loss of signal can therefore
occur as soon as a readjustment is no longer possible. In settings other than
Auto
, there
is no automatic adjustment, which makes it easier to define thresholds for the signal
level warning.
