Parameter: Tilt power characteristic
•
Recommended setting value (_:6331:103) Tilt power characteristic = +20°
The Tilt power characteristic parameter is used to incline the pickup characteristic. In the example
(see Figure 7-175), the power characteristic has a tilt of 20°. Set the Tilt power characteristic param-
eter to +20° (for a definition of the sign, see
Parameter: Dropout delay
•
Recommended setting value (_:6331:7) Dropout delay = 20 ms
The Dropout delay parameter maintains the pickup even if the measured value drops momentarily below
the threshold value. A delay is required for very low pickup values to prevent a so-called chattering of the
function. In the example, the setting value is 20 ms.
Parameter: Operate delay
•
Recommended setting value (_:6331:6) Operate delay = 100 ms
The Operate delay must be set for the specific application. In the example, a setting value of 100 ms has
been selected.
