Diesel Version 5:Short Circuit Protection
Starting with version 5 WOWSound decoders have a limited ability to protect themselves against short circuits in the motor and light circuitry. When the decoder senses a short circuit it will announce the short and even tell you what is shorting. The shorted component will be turned off for 5 seconds and then be turned back on, if there is still a short the decoder will announce the short again and shut off power for another 5 seconds. During that time the rest of the decoder will still be active.
CV112 Short Circuit Trip Level controls the trip settings for the short circuit protection. See below for how to use CV112.

NMRA CV 112 - Beta testing short circuit trip point motor offset
This CV is temporarily used for beta testing. Only mess with this CV if you find the decoder talking to you and saying there is a motor or light short circuit when there isn't actually one. TCS allowed the trip point to be programmable by beta testers because we are assuming not all locomotives act alike and will need customizing. Once we get feedback from the Beta testers we will modify the default values, thanks for helping us figure out the best values!
CV112 controls how much current is added onto the base trip point in Short Circuit Trip Point Base CV when the motor is running.
Each value adds .35 Amps to the trip point, the value can go up to 15. giving a total range of 0 Amps to 5.25 Amps.
Example:
.7 amps when the motor is on in addition to the base trip point
Additional amperage allowance when motor is on .7A / .35A per value = value of 2 in CV112
Additionally the harder the motor is working the higher the trip point will get set by decoder code internally, but you don't need to worry about that as its not user programmable. If you find false motor shorts and certain speeds but not others please let TCS know what speeds it falsely trips at
