Connection of the points: > 0.25 mm Connection of motor-run points The KSM-3 has a connection to which points with double coil drive can be directly connected. To be able to connect motor-run points, you also need an adapter: ...
KSM-3 1.3. Intended use The loop module is intended for use in model railway layouts as specified in the instructions. Any other use is not in accordance with the intended use and will result in the loss of the warranty claim.
KSM-3 changes the polarity within the terminal loop. The response time is extremely short, as the KSM-3 already detects the voltage drop at the switchover to a short-circuit. In consequence, the KSM-3 is able to react within milliseconds before the voltage breaks down due to the short circuit.
KSM-3 2.3. Procedure Phase 1: According to the current position of points the locomotive runs clockwise or counter- clockwise through the terminal loop. When the train is intended to run in a specific direction through the loop, the points can be set accordingly from the outside.
With turntables different polarities possibly meet at the transitions between bridge and the other parts of the layout after turning the bridge. The KSM-3 can solve this problem. For that purpose you have to connect the bridge like the loop´s inside.
KSM-3 3. Assembling the kit You can skip this section if you have purchased a ready-built module or device. 3.1. 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.
KSM-3 tams elektronik 3.2. Soldering properly Use a soldering iron with temperature control, which you set to approx. 300 °C. Only use electronic solder with a flux. Never use soldering water or soldering grease when soldering electronic circuits. These contain an acid that destroys components and conductor paths.
KSM-3 3.3. Preparation Put the sorted components in front of you on your workbench. The separate electronic components have the following special features you should take into account in assembling: Resistors Resistors reduce current. The value of resistors for smaller power ratings is indicated through colour rings.

KSM-3 tams elektronik 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). Light emitting diodes should always be connected via a series resistor which limits the current and prevents failure.
KSM-3 Relays Relays are electronic switches, depending on their position the one or other (internal) connection is closed. The mode of operation of monostable relays can be compared to that of a push-button switch, i.e. the connection is only closed as long as the voltage is applicated.

KSM-3 3.5. Assembly Proceed according to the order given in the list below. First solder the components on the solder side of the PCB and then cut the excess wires with the side cutter. Follow the instructions on soldering in section 3.2.
KSM-3 tams elektronik ICs in DIL-housing Insert the ICs into the soldered socket. Do not touch the ICs without first discharging yourself by touching a radiator or other grounded metal parts. Do not bend the "legs" when inserting them into the sockets.
There are two terminal strips for the connection of the rails and a plug-in unit (consisting of a box header and an appropriate plug-in part) for the connection of the points soldered to the module which are used to insert and screw on the connecting wires. Connections KSM-3 | 17...
