Function monitoring
The LED, the active "DC OK" switching output and a potential−free contact provide the
function monitoring.

U input
Device is in operation,
l the output voltage V output
is higher than 90 % of the
set voltage V
input
l the output current is in the
permissible range
BLINKING U = 0 V open V output < 0.9
V input
Device is in operation but
l error at the load
l current consumption is
higher than I
BOOST
l output is short−circuited
OFF U = 0 V open V output = 0 Device is out of service because
l no mains voltage is applied
l the circuit−breaker is
activated
l the device is defect
)
Note!
The device is defective and needs to be replaced if the mains voltage is applied,
a short circuit can be excluded and an output voltage of V
output
= 0 V is
measured.
