Voltage control with external reference, positive variable
Normally used to control proportional valves with 12 V and 24 V power.
Available control range will be from 5-95% of external voltage. Control signal will be positive
variable relative the external reference voltage minus.
Zero output = External power/2.
Zero setting and control range output at U_CTRL can be adjusted in dockside setup. See
“Rudder feedback/tunnel thruster feedback calibration” on page 51 .
For Analog output, external voltage, the switch must be set to EXT.
