English SAS modules
4. Operation overview
The SAS controls a modelling servo. It has been designed to be
controlled and adapted to individual requirements with push-buttons.
This allows you to use the complete functional range in analogue
layouts. It is possible to control the SAS via digital points (solenoid)
decoders as well and so to integrate it in digitally controlled layouts.
Controlling the servo
The servo´s motion sequence is controlled by a micro controller. The
several versions of the SAS generate typical motion sequences for
different objects. With each of the versions SAS-4 and SAS-5 there are
two optional variations.
The motions are released with push-buttons connected to the inputs of
the module.
Controlling via a points decoder
In order to integrate the servo control into a digitally controlled layout,
the SAS can be connected to a points (solenoid) decoder. Note: Points
decoders designed for controlling switches with motor drives are not
suitable to control the SAS.
Each input of the SAS is assigned to one points address and one switch
stand. Generally a relay has to be switched into the connection
between input of the SAS and points decoder output as a decoupling
between analogue and digital system.
When controlling the SAS via a digital decoder, push-buttons can be
connected in parallel, which allows you to release the servo motion
both analogue and digitally.
