2.11 Beeper
A beeper indicates the output of voltages and/or currents. The behavior of the beeper can be
configured in the CMC 430 Web Interface (accessing the Web Interface → Getting Started manual of
the controlling software).
Beeper mode Description
Beeper enabled The beeper is enabled by default. Two modes can be selected:
• One short beep (0.1 s) at the beginning of the voltage/current output
on the outputs VOLTAGE OUTPUT 1 ... 6,
CURRENT OUTPUT 1 ... 3 or AUX DC OUTPUT
• Intermittent beep (0.1 s on/2 s off) during the output of voltages/
currents on the outputs VOLTAGE OUTPUT 1 ... 6 and/or
CURRENT OUTPUT 1 ... 3; short beep at the beginning of the
voltage output on output AUX DC OUTPUT
Overload indication:
Intermittent beep (0.1 s on/0.5 s off) in case of an overload on one of
the outputs VOLTAGE OUTPUT 1 ... 6, CURRENT OUTPUT 1 ... 3 or
AUX DC OUTPUT
Beeper disabled The beeper can be disabled temporarily.
The output AUX DC OUTPUT can be programmed to automatically output a configured
voltage after the start-up of the CMC 430. If so, the CMC 430 issues an intermittent beep
(0.1 s on/0.5 s off) for a period of 20 s after start-up to indicate that voltage will be applied at
this output upon expiry of this period. This warning beep cannot be configured or disabled!
→ AUX DC OUTPUT section on page 14
If you reduce the voltage setting for the AUX DC OUTPUT from a high value of, for example
220 V, to a low value of, for example 24 V, and you have enabled the beeper in the CMC 430
Web Interface, you will hear an intermittent beep while the voltage reduces from the high to
the low value.
