BM 70 M 39
Function (Fct.) Enter range Default value Description
3.6.3 THRESHOLD Value
-200.00 ... +200.00 [m]
0.00 ... 99999.99 [m3]
0 ... 100 [Refl.]
5.00 m
5.00 m3
50 Input of the threshold
value for the
switching output.
(Input is dependent
on the function of the
switching output. The
values for level and
distance include the
tank bottom and
reference offset,
resp.)
3.6.4 HYSTERESIS Value
0.00 [m] ... Tank height
0.00 ... 99999.99 [m3]
0 ... 100 [Refl.]
0.10 m
0.10 m3
10 Input of the
hysteresis for the
switching output.
(Input is dependent
on the function of the
switching output.)
*:Default values following a parameter reset (use of a new EEPROM not yet described).
The factory setting for the parameters marked with * is dependent upon the device version and
customer specifications (if the tank height is known at the time the order is placed).
