R ( G, B ) Break on and R ( G, B ) Paper: These are stored signal values during Break and Paper.
Auto limit calculation is using these values to perform detection limit and other values. These are
only for indication in this menu to help select correct alarm limits.
Measurement config(uration):This section determines detection speed (Detect filter), measurement
intervall (cycle), light emission intensity and detector sensitivity.
Fig. 4.7. Measurement settings.
Detect filter: Set number of measurement cycles for break determination, default 3. Number 3 means
that 3 consecutive measurements are all below detection limits before break relay is activated.
Meas. cycle: Set the measurement cycle time, default 20 ms. Can be between 10 and 60 ms.
Tx Power: Select light source intensity, High/Normal. High can be chosen when the measurement
distance is high, for example over 20 cm.
Rx Gain: Detector gain – normally 1 (selectable 4.0, 3.5, 3.0, 2.5, 2.0, 1.5, 1.0, 0.5). Effects directly
on signal level. Can be adjusted lower if ambient light is too high (over 60 %).
