Output voltage Description
ON U = 24 V closed U
output
>0.9U
input
Device is in operation,
z the output voltage U
output
is
higher than 90 % of the set
voltage U
input
z the output current is in the
permissible range
BLINKING U=0V open U
output
<0.9U
input
Device is in operation but
z error at the load
z current consumption is higher
than I
BOOST
z output is short-circuited
OFF U=0V open U
output
=0 Device is out of service because
z no mains voltage is applied
z the circuit-breaker is activated
z the device is defect
