Terminal loops
Terminal loop sections are built by two tracks sections next to each other (each con-
nected with a 3-pole plug).

PRELIMINARY TEXT:
Switching terminal loops - new strategy
At terminal loops both outputs are connected inversely,
when reaching the lowest overcurrent threshold (three values UELS, UESS, KUS),
the first time its polarity is reversed and other reactions are suppressed,
and the KS-polarity-reversing-time doubled to 2-fold detection
the second time (waiting for second measurement), double polarity-reverse time,
then x4, then x8, then (instead of 16) normal UES or short circuit handling
at restart after UES or KS again process as above
Display
of coherence of both sections and the current polarity
Polarity display by HLU-LEDs:
long (0,4 sec on) - short (0,1 sec off) on P-pole / long (0,4 sec off) - short (0,1 sec on) on N-
pole,
when changing (starting with first switch for 2 sec): full on P-pole / dark on N-pole
(so, immediate synchronous visualization of every change).
With every short circuit that leads to reversing the polarity: Blue LED flashes
Occupancy LEDs of both outputs always synchronized (occupancy and RailCom)
Special measurement and display as indicator for probably too low set central command station:
If there is no repolarisation on the terminal loop section (ONLY at terminal loop sections) current
jump > 1 A and there is NO repolarisation (because MX10 obviously does not supply enough cur-
rent), warning by rapid jumps of the two yellos LEDs (inverted flashing with about 5Hz) for 5 sec
as warning for possibly failed plolarity-reverse attempt)
