Preventive DC OK Function Monitoring
The DC OK LED (see Figure 1, point 4) provides
function monitoring.
Green "DC OK" Flashing
LED
Description Output voltage > 27 V
Meaning Output voltage and current
OK
ON
Output voltage < 27 V
QUINT POWER operating,
but:
– Error at the load
– Current consumption
greater than I BOOST
– Output short circuit
OFF
No voltage at the output
QUINT POWER not
operating, because:
– No mains voltage present
– Primary side fuse is
blown
– Device is faulty
EFD Ground Fault Monitoring
Figure 9
EFD ground fault monitoring
An EFD LED (see Figure 1, point 5) and a floating
switching output are used to evaluate a ground fault
detected in the AS-i system.
When a ground fault is detected, the LED lights up,
the floating EFD output is opened, and in switch
position "EFD internal" (see Figure 1, point 7), the
device switches off. To restart, press the reset button
(see Figure 1, point 6) for > 2 seconds.
In switch position "EFD external", the device
continues to detect ground faults.
Briefly activating the reset button (< 1 second)
simulates a ground fault.
