DC OK LED lit OFF
Meaning Output voltage > 21.5 V Output voltage < 21.5 VDC, overload mode or no mains volt-
age
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.
Corrective  Remove the error at the load, use a more powerful power
supply unit, connect a power supply unit of the same type
parallel to the existing device, remove the short circuit, apply
mains voltage, enable the fuse again or replace the power
supply unit.
