Slow short circuit detection is best for layouts using heavy lamp loads and/or
slower boosters.
Standard short circuit detection works for most HO locos on most Digitrax lay-
outs.
Faster short circuit detection can be used with most HO & N scale locos on
most Digitrax layouts. Faster short circuit detection should be used with auto-
reversing sections of your PM42.
Fastest short circuit detection for use with decoders that are particularly sensi-
tive to power interruptions, and should be the setting for autoreversing.
