The light sequences of the blue LED
shown here in overcurrent situations
(i.e. alternately flickering or lit solid)
can only happen if the shutdown times
are relatively large (from @ 500 ms),
otherwise a solidly lit LED with very
brief interruptions is more likely.

Blue LED
According to the configuration settings (shutdown times, reset times), overcurrents or short circuits are indicated by the blue LED in
particular phases of track power off (= blue LED ON) and reset attempts (= blue LED flickers).
Overcurrent threshold UESLAMP
-
“long” overcurrent threshold is
exceeded.
Blue LED flickers at 10 Hz.
Power is restored after UESLEZT
expires (long reset time, i.e. 2
sec.)
Blue LED flickers again.
According to UESLEAZ (quantity i.e. 5),
several resets are attempted.
Blue LED flickers/lights up alternately.
Blue LED
Power turns off after UESLAZT
expires (“long” overcurrent time,
i.e. 2 sec.)
Solid blue LED.
Power turns off after UESLAZT
expires (“long” overcurrent time,
i.e. 2 sec.)
Solid blue LED.
Overcurrent conditions (current via UESLAMP, i.e. 1.5
A) are no longer exceeded. That ends the overcurrent
sequence, back to normal.
Blue LED is dark again.
Temporary overcurrent situation which
ends "in time", whereby a shutdown is
not initiated
IF it leads to a shutdown:
Blue LED is ON continuously,
Yellow LED indicates the reason for the
shutdown by means of the flashing rhythm.
Power is restored after UESLEZT
expires (long reset time, i.e. 2
sec.)
Blue LED flickers again.
According to UESLEAZ (quantity i.e. 5),
several resets are attempted.
Blue LED flickers/lights up alternately.
Power is permanently turned off after the last at-
tempted reset (i.e. 5).
Blue LED is ON, yellow LED flashes at 1 Hz
(Sign of a “slow overcurrent”).
Overcurrent threshold UESSAMP
-
“fast” overcurrent threshold (i.e. 2.5A) is
exceeded.
Blue LED flickers at 10 Hz.
Yellow LED
Power turns off after UESSAZT
expires (“fast” overcurrent time, i.e.
1 sec.)
Solid blue LED.
Power is restored after UESLEZT
expires (“fast” reset time, i.e. 1.5
sec.)
Blue LED flickers again.
According to UESLEAZ (Quantity i.e. 8),
several resets are atempted.
Blue LED flickers/lights up alternately.
Power is permanently turned off after the last at-
tempted reset (i.e.after 8).
Blue LED is ON, yellow LED flashes at 2 Hz
(Sign of a “fast overcurrent”).

Short circuit threshold KUSAMP
(i.e. 4A)
is
exceeded, leads to immediate shutdown.
5 reset attempts after every 100 msec.
Blue LED flashes at 10 Hz.(~ 100 msec).
20 more (fixed number) resets are attempted in in-
tervals according to KUSEZT
(short circuit reset time, i.e. 200 msec.)
Blue LED flashes at 5 Hz.(~ 200 msec).
Power is permanently turned off after the last at-
tempted reset (after 25
– fixed number).
Blue LED is ON, yellow LED flashes at 5 Hz
(Sign of a “short circuit”).
Short circuit threshold KUSAMP
(i.e. 4A)
is
exceeded, leads to immediate shutdown.
5 reset attempts after every 100 msec.
Blue LED flashes at 10 Hz.(~ 100 msec).
20 more (fixed number) resets are attempted in inter-
vals according to KUSEZT
(short circuit reset time, i.e. 200 msec.)
Blue LED flashes at 5 Hz.(~ 200 msec).
Short circuit conditions (current above KUSAMP,
i.e. 4 A) are no longer present. This ends the short
circuit sequence, power back to normal.
Blue LED is dark.

NOTE: The timelines shown here are
examples
and correspond to finished
configurations for
a typical HO layout.
The shutdown behavior can be changed
by editing the parameter sheet entries
(UESLAZT, UESLEZT, UESSAZT etc.)
