4.2.4.2 Non-Interlocked Functions
Contrary to interlocked settings, non-interlocked settings allow the two adjacent push
buttons be used simultaneously. Non-interlocked settings are usually applied to a crane’s
auxiliary functions, such as lights, a horn, 3
rd
speed and auxiliary stop. Each dip-switch
on the decoder module corresponds to one (1) motion or two (2) adjacent push buttons
(left & right push buttons).
