Page 3: Getting Started
Intended use The loop module KSM-2 is designed to be operated according to the instructions in this manual in model building, especially with model railways. Any other use is inappropriate and invalidates any guarantees. - Page 4 English KSM-2 Checking the package contents Please make sure that your package contains: one kit, containing the components listed in the parts list ( page 18) and one PCB or one ready-built module with a jumper put onto JP1 or ...

Page 5: Safety Instructions
KSM-2 English 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. Visibly damaged parts can cause unpredictable danger. Do not use damaged parts: recycle and replace them with new ones. - Page 6 English KSM-2 Fire risk 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.

Page 7: Safe And Correct Soldering
KSM-2 English 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. 3. Safe and correct soldering Caution: Incorrect soldering can cause dangers through fires and heat. Avoid these dangers by reading and following the directions given in the chapter Safety instructions. - Page 8 English KSM-2 To make a good soldering joint you must use a clean and unoxidised soldering tip. Clean the soldering tip with a damp piece of cloth, a damp sponge or a piece of silicon cloth. Cut the wires after soldering directly above the soldering joint with a side cutter.

Page 9: Operation Overview
KSM-2 English 4. Operation overview Loop problems At the loop points in two-rail-systems, different polarities meet with each other. As soon as a vehicle bridges the differently polarized sections when driving in or out the terminal loop a short circuit occurs. - Page 10 English KSM-2 Mode of operation of the KSM-2 The loop module KSM-2 changes the polarity within the loop before a short cicuit occurs – independently of the locomotive´s direction of travel or the data format used to control the locomotive.
- Page 11 Fig. 2: Procedure Track busy indicator conducted to the outside The track busy indicator integrated into the KSM-2 which supervises the section within the loop, is conducted to the outside of the module and can be integrated into the rest of the layout´s control system. As it is galvanically separated from the rest of the circuit, digital feed back modules (e.b.
- Page 12 This would invalidate the loop module´s function. The KSM-2 has a special connection for a RailCom detector which allows to link the terminal loop to a layout supervised by RailCom.

Page 14: Assembling The Kit
English KSM-2 6. Assembling the kit You can skip this part if you have purchased a ready-built module or device. Preparation Put the sorted components in front of you on your workbench. The separate electronic components have the following special features... - Page 15 KSM-2 English Electrolytic capacitors Electrolytic capacitors are often used to store energy. In contrast to ceramic capacitors they are polarized. The value is given on the package. Electrolytic capacitors are available with different voltage sustaining capabilities. Using an electrolytic capacitor with a voltage sustaining capability higher than required is always possible.
- Page 16 English KSM-2 Transistors Transistors are current amplifiers which convert low signals into stronger ones. There are several types in different package forms available. The type designation is printed on the component. Transistors for a low power rating (e.g. BC types) have a package in form of a half zylinder (SOT-package).
- Page 17 KSM-2 English Opto couplers Opto couplers are ICs, which work similar to laser beam switches. They combine in one housing a light emitting diode and a photo transistor. Their task is the transmission of information without galvanic connection. They are in a DIL-housing with at least 4 pins.

- Page 21 KSM-2 English Transistors Observe the polarity! The cross section of transistors for a low power rating in SOT-packages is shown in the PCB layout. With transistors for a high power rating in TO packages (e.g. BT types) the unlabelled back side is marked in the PCB layout by a thick line.
- Page 22 English KSM-2 Performing a visual check Perform a visual check after the assembly of the module and remove faults if necessary: Remove all loose parts, wire ends or drops of solder from the PCB. Remove all sharp wire ends.

Page 23: Connecting The Ksm-2
KSM-2 English 7. Connecting the KSM-2 Dividing the loop into sections Divide the loop into three sections according to fig. 4: two transition zones near the points and the inner section of the loop. Isolate both rails in each case. The transition zones should be about half as long as the longest locomotive, the inner section as long as the longest train. - Page 24 (optional connection) Voltage supply (tranformer) 3 | 4 The polarity is of no importance. Caution: Do not connect the KSM-2 to the power supply of the digital system. The occuring fault current can damage the module irreparably! 5 | 6 Transition zone 1 →...
