a. Interlocked Functions
Interlocked means the two adjacent push buttons can not be activated simultaneously as
they will cancel each other out. Interlocked settings are usually applied to a crane’s
forward and reverse motions. Each dip-switch on the decoder module corresponds to
one (1) motion or two (2) adjacent push buttons (refer to Fig. 14 & 15 below). Only the
first seven (7) dip-switch positions are used (counting from left to right); the 8
th
dip-switch
position (far right) is not used.
