Description
The voltage converter is performing a self-test.
-
The display will switch off after a brief period.
Input voltage drops below 10.5 V �0.3 V.
The voltage converter stop inverting power and the external
device will be switched off. If the voltage rises to over 12 V �0.5 V,
x
the voltage converter will resume normal operation.
If the input voltage drops below 9.5 �0.3 V, the voltage converter
will switch off. Press the
button [19] for approx. 3 sec. to restart the voltage converter.
Input voltage rises over 16 V �0.3 V.
The voltage converter stops inverting power and the external
x
device will be switched off. If the voltage drops below 14 V �0.5 V,
the voltage converter will resume normal operation.
Connected load is above the maximum output power (see „Tech-
nical Data").
x
The voltage converter stops inverting power and the external
device will be switched off.
The housing temperature is above 60 ° C.,
x
If the temperature drops below 45 ° C, the voltage converter
resumes normal operation.
x
The connected device caused a short-circuit.
