Setup procedure for Set voltage
The UCS 500 is able to control an external voltage source with a 0-10V analogue dc signal.
The 10V level corresponds to the max. output voltage of the connected voltage source. For the correct setting it
is necessary to know the max. output voltage of the source. For setting for ac or dc source the same procedure is
necessary.
Setup for adjust the external voltage variac to the UCS 500Nx
The voltage setting is a regulating procedure where one
winding of the motor-variac is approx. 1.9V. Additionally
the control needs some mechanical tolerance for stop
the step motor. Therefore the selected voltage is
normally in a tolerance of
3V
The motor-variac control has an internal deadband
where the voltage will not be adjusted.
The following procedure will guide the user through the Set Voltage procedure.
The setting for Umax and Un are listed in the boxes below. After each setting the user has to
press the ESC
button
for make the setting.

If the output voltage is not inside the tolerance or you like to make a better adjustment:
- Change the Umax voltage and restart the check procedure from step C to G.
