5 Inputs and Outputs
5.1 Inputs
5.1.1
Set value “Set”
The set value can be applied externally via an analogue voltage or internally
using potentiometer
P3
.
If the set value is applied externally using the “+Set” and “-Set” connections,
DIP switch
S9
must be in the “ON
Ð
” position
.
Two different ranges can be selected to apply an external analogue set value.
The required range is determined by the position of DIP switch
S10
.
