The ESU 51832 SwitchPilot 3 Servo is an outstanding 8 - channel servo decoder designed for DCC and MM systems. It comes with an OLED display and RC - feedback, and can be updated. Optimized for stationary use, it can control up to eight RC servo drives. The innovative operating concept, featuring a 4 - line, illuminated OLED display and three input buttons, simplifies the configuration process. This multi - protocol servo works with Märklin® Motorola® workstations and DCC - enabled central stations. Configuration can be done on both the main and programming tracks, and CVs can be read out via RailCom®. It can be powered directly from the digital system or an external voltage source. With eight outputs, it precisely controls RC servo drives for various movement sequences. It has power - on pulse suppression to reduce servo 'twitching' and can interrupt power to prevent servo 'hum'. Each servo can operate in 'digital mode' for fixed - position applications like switches and signals, or 'proportional mode' for applications needing intermediate positions such as cranes and gates. Additionally, it can be used without a digital control panel by connecting up to 16 buttons for direct servo switching.

Using the SwitchPilot 3 Servo is quite straightforward. First, decide on the power source. You can either connect it directly to the digital system or use an external DC or AC voltage source. When it comes to configuration, you can do it on the main track or the programming track. If you're using a Märklin® Motorola® workstation or a DCC - enabled central station, just follow the normal setup steps for those systems. For reading out CVs, rely on the RailCom® feature. To control the servos, you have two modes. In digital mode, the servos move between two end positions 'A' and 'B' based on the control panel's switching position. You can set the end positions and the speed of movement on the servo itself. This mode is great for things like switches and signals that always stay in a fixed place. In proportional mode, the servo moves and stops according to the commands from the control panel. Release the button, and the servo stops. It's ideal for applications where you need intermediate positions. You can also adjust the speed individually. If you want to use the servo without a digital control panel, you can connect up to 16 buttons for direct switching. As for maintenance, keep it clean and dry. Make sure the connections are secure. If you notice any issues with the servo 'twitching' or 'humming', you can use the built - in power - on pulse suppression and power interruption features to solve them. Also, since it's an updatable device, check for updates regularly to ensure it works at its best.
