12 Signaling
For signaling and the functional monitoring of the power
supply two LEDs and an active signal output are available.
Using the rotary selector select the required functional
monitoring. The monitoring of the output voltage (DC OK) or
the exceedance of the output power threshold are available
(P
Out
> P
Thr
).
12.1 Rotary selector switch in position DC OK:
In this switch position the output voltage (U
Out
) is monitored.
If the DC OK threshold is exceeded (U
Out
> 0.9 x U
Set
) the
green DC OK LED turns on. Additionally, the signal output
(SIG) "active high" is active. If the output voltage drops
below the DC OK threshold value (U
Out
< 0.9 x U
Set
), the
DC OK LED flashes. The signal output is switched to "active
low".
12.2 Rotary selector switch in position >50 %, >75 %
or boost >100 %:
In each of these switch positions the output power (P
Out
) is
monitored. When the set threshold is exceeded the yellow
LED lights up (P
Out
> P
Thr
) and the signal output (SIG)
switches to "active low".
