Loco-1 / Loco-2 Safety advices Before you start using this product or its installation read these instructions carefully. This product is not a toy. Not suitable for children under 14 years! Keep these instructions for future reference! This module is intended to be integrated into a model railway system for driving a locomotive model within the limits indicated in Chapter 3 - "Technical specifications".
Loco-1 / Loco-2 When making electrical connections pay attention to sufficient wire cross section. After the formation of condensate on the parts wait for at least two hours for drying off before you switch power on. Danger of burns! Some components on the decoder can achieve a...
This manual applies starting from firmware version 9 for Loco-1 and firmware version 5 for Loco-2. Any firmware updates may include other new features that are not included in this manual. An updated manual is supplied as a PDF file with the new firmware, if needed.
Loco-1 / Loco-2 Mounting Open the locomotive housing according to the manufacturer's instruc- tions. Determine the location where you want to install the decoder. First disconnect the connections of the motor and the consumers from the rail collectors or, for locomotives with electronic or electro- mechanical switch, the connections of the switch to the motor and to the rail collectors.
Loco-1 / Loco-2 The picture below shows the connections: Connection of the rail collector In a two- rail-loco connect the lines of the two current collectors with either of the two solder points with the label ‘Rail’. In a three-rail-loco, connect the locomotive ground with one of the two solder pads called ‘Rail’.
Loco-1 / Loco-2 Attention: The interference suppression devices which are fitted to the motor or the cable to the motor must not be removed! Considerable electrical interference may occur, if this interference suppressors are removed. Connecting a DC motor: Connect either of the two terminals of the motor with one of the two solder points labeled ‘MOT '.
Loco-1 / Loco-2 Connection of LEDs as a consumer The function outputs (AUX1 to AUX 4) are switched towards the decoder ground. Therefore the cathode (-) of the LEDs have to be connected to the output of the function outputs (AUX).
Loco-1 / Loco-2 Decoder functions Digital operation The decoder is a multi-protocol decoder. It automatically detects whether it is driven in DCC format or the Märklin® / Motorola format. The automatic detection can be disabled. The address range depends on the format in which the decoder is controlled: Märklin®/Motorola-Format: 255 or 80 addresses (depending on the...
Loco-1 / Loco-2 Motor control The detection of the connected motor type is automatic. The auto- matic detection can be switched off and the motor type can be set manually. Note: If the loco does not run in analogue mode or only approach at high driving voltages, switch off the automatic motor recognition and set the appropriate motor type correctly.
Braking section The decoder supports the Märklin® braking section. The mode can be adjusted via the corresponding CV. Only Loco-1: In addition the decoder supports the simple ABC-(DCC) braking section. Both types can be combined. V1.2 - English page 12 of 36...
Loco-1 / Loco-2 Function outputs The decoder has four function outputs to which consumers can be connected based onto needs (e.g. lighting, smoke generator, sound module, electrical coupling). The function outputs are switched in DCC format using the function keys F0 to F12. In Motorola format, the function outputs are switched with the function keys F0 to F4.
Loco-1 / Loco-2 Flash function A small flash sequence can be programmed by programming up to 2 on and 2 off times in the corresponding CVs. Thus, for example a flash or a blinking light can be set (individually or alternately). The flashing mode can be set to any of the 4 function outputs and using the F key on and off.
(RailCom® detectors). The decoder must be configured to send the so called RailCom® data packets. In addition, the booster or the DCC central must produce a cutout signal (blanking), within which the data is transmitted.
Loco-1 / Loco-2 Decoder configuration/programming Programming with a DCC Station From the control center, you can program the configuration variables (CV). Please refer to the relevant section in the user manual of your control center, in which the byte-wise programming of CV variables is described (Direct CV Addressing).
Loco-1 / Loco-2 Once the lighting of the vehicle starts to flash (after about 2 seconds), the decoder is in the programming mode, and you can release the direction switch. After you start the programming mode, you can program the registers of the decoder as follows: Select a register to program by selecting the register number as Märklin®/Motorola locomotive address.
Loco-1 / Loco-2 Example: If you want to program the value of 197 (bit value 11000101) into the register 90, proceed as follows: Program a 3 into the register 8 to set the two most significant bits (binary = 11 decimal 3)
Loco-1 / Loco-2 Programming with a Märklin Mobile/Central ® Station With the Central Station and the Mobile Station from Märklin®, you can program the registers. To do this, select the article no. 29750 (V100) from the locomotive database and program the decoder as described for this article no. in the instructions of the Central Station or the Mobile Station.
