CHANGING PARAMETERS FOR ANALOGUE SENSORS

The sensors resolve distances to 0.36mm increments and output the measured distance with the same

resolution. The resolution is independent from the selected detection range and also independent from the

selected window margins.

INNER WINDOW MARGIN / OUTER WINDOW MARGIN

The turning points of the analogue output curve are selected by the inner window margin and the outer

window margin. In between these two distances the analogue output signal runs linearly - rising or falling

ac-cording the selected output slope.

CHARACTERISTICS

By the selection buttons rising / falling the output characteristic can be toggled between rising (0 - 10 V or

4 - 20 mA) or falling (10 - 0 V or 20 - 4 mA) slope of the analogue output curve.

OUTPUT TYPE

Ultrasonic sensors with automatic changing of voltage- current output check the output load resistor and

switch autonomously to current or voltage output mode depending on the result. Checking the output load

take place every time when the device is powered up. If the load resistance is low (< 500 Ohm) the

analogue sensor go for the current output; if the load is high (> 10 kOhm) for voltage out-put.

The automatic changing of voltage- current output can be switched off and the type of the output can be

programmed as a fixed output type (voltage or current).
