8.6. DC recognition
8.6.1. Description
In emergency light systems with central battery supply the DC recognition function uses the input voltage to detect that emergency
mode is in place. The LED Driver then automatically switches to DC mode and dims the light to the defined DC level. Without DC
recognition different and more complex solutions need to be applied in order to detect emergency mode.
8.6.2. Commissioning
The function is integrated in the device as standard. No additional commissioning is necessary for activation.
...
LED Driver of the LCA PRE series are factory preset to a DC level of 15 %. This value can be customised. Further information
can be found in the masterCONFIGURATOR manual (see
).
_
LED Driver of the LC EXC series have different DC levels. Further information can be found in the data sheet of the
corresponding LED Driver (see
).

NOTICE
The LED Driver is designed to operate on DC voltage and pulsing DC voltage.
In DC recognition connected sensors are ignored.
