Page 3: Getting Started
Any other use is inappropriate and invalidates any guarantees. The Multi-Timer should not be assembled or mounted by children under the age of 14. Reading, understanding and following the instructions in this manual are mandatory for the user. - Page 4 English Multi-Timer Caution: The Multi-Timer contains integrated circuits. These are very sensitive to static electricity. Do not touch components without first discharging yourself. Touching a radiator or other grounded metal part will discharge you. Checking the package contents Please make sure that your package contains: ...

Page 5: Safety Instructions
Multi-Timer English For the connection to the switching inputs you need: for use as a time switch or a pulse delay (operation mode 1 or 2): four push buttons, e.g. item no. 84-5212x, x=1..5 (or circuits to release a switching pulse);... - Page 6 English Multi-Timer Never perform wiring on a powered module. Assembling and mounting the kit should only be done in closed, clean, dry rooms. Beware of humidity. Only use low power for this module as described in this manual and only use certified transformers.
- Page 7 Multi-Timer English Dangerous environments A working area that is too small or cramped is unsuitable and can cause accidents, fires and injury. Prevent this by working in a clean, dry room with enough freedom of movement. Other dangers Children can cause any of the accidents mentioned above because they are inattentive and not responsible enough.

Page 8: Safe And Correct Soldering
English Multi-Timer 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. Use a small soldering iron with max. 30 Watt or a regulated soldering iron. - Page 9 Multi-Timer English 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.

Page 10: Operation Overview
Setting the mode of operation The mode of operation has to be set by means of jumpers. The operation modes 1 and 2 are set to the 4 outputs of the Multi-Timer individually. Thus using one Multi-Timer as a combined time switch and pulse delay is possible. -
Page 11: Operation Mode 1 "Time Switch
In order to release a switching pulse push-buttons or comparable external circuits can be used. In this operation mode the Multi-Timer can be set either to allow it to be retriggered or not. -

(and the train brought to a stopp), as soon as the train has passed a reed contact. In case the train would stop immediately after passing the reed contact, it would be impossible to switch on the rail section again. With the Multi-Timer it is possible to Page 12... -
Page 13: Operation Mode 3 "Random Switch
4.3. Operation mode 3 "Random Switch" Use in analogue or digital layouts The 4 outputs of the Multi-Timer are switched separately for a time at random. The time interval after which the random generator decides whether to release a switching operation or not, can be set for each output individually via a trimpot, the maximum interval is 4,5 minutes. -
Page 14: Operation Mode 4 "Start-Brake-Stopover Switch
English Multi-Timer 4.4. Operation mode 4 "Start-Brake-Stopover Switch" Use in analogue layouts only The Multitimer controls braking, stopping and starting of analogue locomotives (e.g. in a station or at a signal stop). optionally: the signal position (stop or clear) ... - Page 15 Multi-Timer English Sequence Via a switch connected to switching input 1, the signal is set to "stop" (switching input closed) or to "clear" (switching input open). Semaphore signals are to be switched directly, light signals can be switched via bistable relays as well. It is also possible to do without connecting signals, the outputs 1 and 2 stay then open.
- Page 16 English Multi-Timer 2. The locomotive stops in front of the signal until the hold time has expired (and switching input 1 has been switched to "open" automatically) or until switching input 1 has been opened (e.g. by means of an external switch).
- Page 17 Multi-Timer English Example 2: Signal set to "Clear" (switching input 1 open) Passing the sensor at the beginning of the braking track has no effect, the braking process is not started. The state of switching input 3 has no effects, too.

English Multi-Timer 6. Assembling the kit You can skip this part if you have purchased a ready-built module or device. 6.1. Preparation Put the sorted components in front of you on your workbench. The separate electronic components have the following special features... - Page 21 Multi-Timer English Ceramic capacitors Among other things ceramic capacitors are used for filtering interference voltages or as frequency determining parts. Ceramic capacitors are not polarized. Normally they are marked with a three-digit number which indicates the value coded. The number 104 corresponds to the value 100 nF.
- Page 22 English Multi-Timer 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 high power rating (e.g. BD types, BT types) have a flat package (TO-package), which is in use in different versions and sizes.

Page 27: Connecting The Multi-Timer
7. Connecting the Multi-Timer 7.1. Functional test Especially, when you have mounted the Multi-Timer from a kit, you should perform a functional test before mounting it in your layout. Connect an electric bulb with a separate power supply to output 1 (connections 1 and 2) and a push-button to switching input 1 (connection 9) as described in section 7.3 for operation mode 1. -
