Connection of switching-inputs
If only 1 motor for driving speed detection is connected to X1/3 and X1/4, the two
terminals X1/5 and X1/6 can be used as switching inputs, via which various functions
(see page 36) can be triggered.
All switching-inputs of the sound module are negative switching. To trigger a
function, you have to connect the negative pole of the power supply to the
corresponding input. Generally switching units (such as our OKA-4, RC-SM-4 or
other standard multi-switch-modules) are used for this purpose. These modules are
normally negative switching, that’s why only the output of the switching module must
be connected to the input of the sound module.
