13.2.7 Input voltage OK
If the input voltage of the power supply is interrupted for
10ms, the signal state changes.
Example of use
In the event of mains failure, the power supply continues to
supply the load with energy for at least 20ms. Failure of the
input voltage is signaled after just 10ms, which means that
this information is provided to the higher-level controller at
an early stage. System states can therefore be stored
promptly without any loss of data as a result of the
unexpected failure of the supply voltage.
13.2.8 Remote input
The power supply is switched on and off using the digital
remote input of the power supply. When switched off, power
transmission is deactivated on the DC output side of the
power supply. The load connected to the DC output terminal
blocks is no longer supplied with energy. The operating
mode where the DC output side is deactivated is called
SLEEPMODE.
To switch the power supply to SLEEPMODE, select one of
the three external circuit versions. The external circuit is
wired between signal terminal blocks Rem and SGnd
(signalground).
Figure 24 External wiring versions, enable
SLEEPMODE
To switch the power supply back on, change the external
circuit between signal terminal blocks Rem and SGnd.
Power transmission inside the device is activated again. The
energy for supplying the loads is once again available at the
DC output terminal blocks.

MODE
13.3 LED status indicators
Four LED status indicators are integrated in the front of the
power supply, which indicate the current device state.
The green DC-OK LED indicates the current status of the
output voltage (U
Out
). The DC-OK LED is permanently on as
long as the output voltage U
Out
is ≥ 0.9 x U
Set
. If the value of
the output voltage is < 0.9 x U
Set
, the green DC-OK LED
flashes.
Depending on the required output power of the connected
load, the three P
Out
LEDs, which indicate the current output
power, light up. Assuming that the provided output power is
>50% of the nominal output power, the >50% LED lights up
green. If the demanded power continues to increase until it
is above75%, the <75% LED lights up green in addition to
the >50% LED. If the required output power is then greater
than the nominal device power, the power supply operates
in boost mode. In boost mode, the >100% LED additionally
lights up yellow.
The LED status indicator cannot be configured individually.
