2.8 AUX DC OUTPUT section
The output AUX DC OUTPUT can be used to supply test objects with DC
voltage. The output voltage can be configured to 12 ... 264 V in the CMC 430
Web Interface or the controlling software or device (accessing the Web
Interface → Getting Started manual of the controlling software).
The output AUX DC OUTPUT is galvanically separated from all other
connections of the CMC 430.
The output is protected against short-circuit and overload conditions. The
voltage amplifier is additionally protected against overtemperature.
An LED in the upper left corner and the internal beeper indicate the occurrence
of overload conditions and that voltage is applied at the output (→ Beeper on
page 16). Overload conditions are also indicated in the controlling software or
device.
LED state Description
Red Output is active
Red blinking Overload or short circuit
20 s time period without voltage output after start-up
→ "Aux DC voltage output after start-up" below.
OFF Output is inactive
Aux DC voltage output after start-up
In the controlling software or device, the output AUX DC OUTPUT can be
programmed to automatically output a configured voltage after switching the
CMC 430 on. If so:
• No voltage is output for the first 20 s after the start-up of the CMC 430.
• The LED blinks red and the CMC 430 issues an intermittent beep (0.1 s on/
0.5 s off) during this period of time.
• Upon expiry of this 20 s period, the configured voltage is available at output
AUX DC OUTPUT. The LED lights continuously and the beeper falls silent.
NOTICE
Damaging of connected equipment possible.
The AUX DC OUTPUT can be programmed to output voltage without user
intervention directly after start-up.
► Check the voltage configured for this output before connecting a device.
NOTICE
Equipment damage possible.
Infeed of voltages from external sources may damage the output.
