If the following maximum load resistance R
L, max
is exceeded, the load resistance R
L
must be
reduced accordingly by parallel connection of R:
f

f
≤
1 kHz: R
L, max
= 10 k
Ω
f

•
The minimum load resistance R
L, min
is calculated as follows:
R
L, min
= (U

Can also be set as a status output; for the electrical connection, see status output connection
diagram.
