English SAS modules 1. Getting started How to use this manual ni k This manual gives step-by-step instructions for safe and correct assembly of the kit and fitting and connecting of the ready-built module, and operation. Before you start, we advise you to read the whole manual, particularly the chapter on safety instructions and the checklist for trouble shooting. You will then know where to take care and how to prevent mistakes which take a lot of effort to correct.
SAS modules English Checking the package contents For assembling the kit you need: an electronic soldering iron (max. 30 Watt) or a regulated soldering iron with a fine tip and a soldering iron stand, a tip-cleaning sponge, a heat-resistant mat, a small side cutter and wire stripper, as necessary a pair of tweezers and long nose pliers, electronic tin solder (0,5 mm. diameter).
English SAS modules 2. Safety instructions Mechanical hazards Cut wires can have sharp ends and can cause serious injuries. Watch out for sharp edges when you pick up the PCB. Electrical hazards ni k Visibly damaged parts can cause unpredictable danger. Do not use damaged parts: recycle and replace them with new ones. el ek ta m Never perform wiring on a powered module. Assembling and mounting the kit should only be done in closed, clean, dry rooms. Beware of humidity.
SAS modules English Fire risk ni Thermal danger k Touching flammable material with a hot soldering iron can cause fire, which can result in injury or death through burns or suffocation. Connect your soldering iron or soldering station only when actually needed. Always keep the soldering iron away from inflammable materials. Use a suitable soldering iron stand. Never leave a hot soldering iron or station unattended.
English SAS modules In schools, training centres, clubs and workshops, assembly must be supervised by qualified personnel. In industrial institutions, health and safety regulations applying to electronic work must be adhered to. Caution: ni ! k 3. Safe and correct soldering ta m el ek Use a small soldering iron with max. 30 Watt or a regulated soldering iron. Only use electronic tin solder with flux. When soldering electronic circuits never use soldering-water or soldering grease.
SAS modules Cut the wires after soldering directly above the soldering joint with a side cutter. After placing the parts, please double check for correct polarity. Check the PCB tracks for solder bridges and short circuits created by accident. This would cause faulty operation or, in the worst case, damage. You can remove excess solder by putting a clean soldering tip on the spot. The solder will become liquid again and flow from the soldering spot to the soldering tip.
English SAS modules 4. Operation overview k 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. ni Controlling the servo tro The servo´s motion sequence is controlled by a micro controller.
SAS modules English Possible settings The motion sequences can be adapted to individual needs. By aid of programming push-buttons you can set: starting and end position of the servo (within the limits given by the maximum servo´s angle of rotation, servo´s rotational speed. k ni Servo control SAS-1 "Linear" tro Linear motion between the two end positions with automatic stop when reaching the end position. Constant velocity.

Operating the push-button 1 once again during the sequence allows you to restart the complete sequence (20 times repeat). In order to break the sequence operate push-button 2.

SAS modules English Light emitting diodes (LEDs) When operated in the forward direction the LEDs light. They are available in several different versions (differing in colour, size, form, luminosity, maximum current, voltage limits). The longer lead of wired LEDs is always the anode (positive pole). ni k Light emitting diodes should always be connected via a series resistor which limits the current and prevents failure.
English SAS modules Electrolytic capacitors Electrolytic capacitors are often used to store energy. In contrast to ceramic capacitors they are polarized. One of the two leads is marked with a minus sign which indicates the mounting orientation. The value is given on the casing. ni k Electrolytic capacitors are available with different voltage sustaining capabilities. Using an electrolytic capacitor with a voltage sustaining capability higher than required is always possible.
SAS modules English Integrated circuits (ICs) Depending on the type, ICs fulfil various tasks. They are polarized and therefore have to be mounted in a certain direction. The most common housing form is the so-called "DIL"-housing, from which 4, 6, 8, 14, 16, 18 or more "legs" (pins) are arranged along the long sides. ni k The mounting orientation is shown by a semicircular or circular marking at the end of the housing, which is also shown on the PCB layout.
English SAS modules Relays Relays are electronic switches, depending on their position the one or other (internal) connection is closed. Their mode of operation can be compared to that of a push-button switch, i.e. the connection is only closed as long as the voltage is applicated. Bistable relays keep their status after switching – comparable to a switch. ni k Relays which combine two switches in one housing are common as well (shortly 2xUM).
