− Individual process signals to be evaluated via external measuring<br />
devices or recording instruments can be connected to the test<br />
sockets.<br />
Standard configuration<br />
• I: X signal flow-rate sensor (0 ... 1 kHz)<br />
• II: Y signal manipulated variable (0 ... 10 V)<br />
• III: ext. SP to connect an external setpoint device<br />
(e.g. 0 ... 10 V; switch controller<br />
to '<strong>Control</strong>ler structure/extern SP'<br />
[refer to operating instructions<br />
