Configuring the ECL 2000
Sensors delivering a
0–10 V signal
28
A 0–10 V sensor is selected by setting Type to 0–10 V. This type of sensor can be
used for measuring:
•
Sun intensity
•
Wind velocity
•
Water flow
•
Energy
•
"Other".
When Type is set to 0–10V, 2 more parameters can be set: Amplific. and Offset.
The function of these is explained in the following.
Amplification, Offset
The sensor applies a voltage in the range 0–10 V to the controller's sensor input.
This voltage must be converted into the correct value. The parameters Amplific.
(amplification) and Offset are used to perform this calculation, as illustrated in
Figure 19.
