10.1 Function monitoring
DC OK LED
The DC OK LED is available for visual function monitoring of the power supply unit.
Status 1 Status 2
DC OK LED Lit OFF
Meaning Output voltage > 21.5 V Output voltage < 21.5 VDC, overload
mode or no mains voltage
State description The device is operating, output voltage
and output current are OK
The device is in operation, but there is a
fault on the side of the consumer; the
current consumption is greater than IN
or the output is short-circuited.
The device is out of operation because
there is no mains voltage, the fuse on
the primary side has been triggered, or
the device is faulty.
Remedy Remove the error at the load, use a
more powerful power supply unit, con-
nect a power supply unit of the same
type parallel to the existing device, re-
move the short circuit, apply mains volt-
age, enable the fuse again or replace
the power supply unit.
