4.4.2. Operating PECO turnout drives
The PECO mode corresponds to the afore mentioned pulse ope-
ration with the exception that to increase the peak current the
overcurrent protection of the output pair is switched off and the
pulse time is fixed to a relatively short time span. This short current
surge is used to optimally control the PECO drives.
Incorrect wiring or a short circuit at an output in PECO mode can
destroy the SwitchPilot 3 decoder!
4.4.3. K83 operation (momentary action mode)
In K83 mode, the output remains active until the button on the
command station or control panel is released. This operating
mode is suitable for turnout drives with end position shutdown
or for uncoupling tracks.
Optionally, the output can also be slowly dimmed up and dimmed
down (so-called „zoom” for incandescent lamp simulation).
K83 operation may cause problems with older DCC command sta-
tions, because they do not transmit the required „Off” command
(e.g.: older Lenz command stations).
