Originally is the motor of the under-floor drive connected to the pc-board via two wires. Remove this two cables by unsolder them from the motor connection and from the pc-board. After unsoldering the two wires you should solder the motor-cable (att ...

- 6 - To prevent an electrical contact to the PC-board by vibration of the motor please stick an isolation tape around the motor and over the two contact plates. The isolation tape should be long enough to isolate the contact plates as well under the pc-board.

- 7 - 3.2.2. Before replacing the protection cover of the turntable as described within the Roco Manual for the turntable within the section “Maintenance of the drive” and after completion of the alteration you have to feed the motor cable through the opening on the protection cover near the motor connections. Each Turntable-Decoder TT-DEC-R will be supplied together with a cable fastener for strain relief and for securing the motor ...

- 8 - 4. Correct position of the turntable sliding switches and the setting or removing of the matching jumper JP1 of the TT-DEC-R: There are two sliding switches at the lower side of the turntable. One of the two sliding switches is market with a “0” and ”1”. For the operation in connection to the Turntable-Decoder TT-DEC-R this switch has always to be set onto position “1”. The second slide switch is marked with the symbol ...

Which wire you connect to which clamp does not matter. The Roco turntable 42615 will be supplied with an 8-poles flat ribbon cable. Please attend to the differences between the flat ribbon cable of the old and the new version of the Roco turntable 42615. The ribbo ...

- 11 - 5.2.2. TT-DEC-R connection to the new version: The 8-poles flat ribbon cable of the new version of the Roco turntable 42615 contains on each side a gray flat plug. Insert the flat plug careful onto the pc-board socket of the TT-DEC-R in direction that the black single wire of the flat ribbon cable is showing to the left as shown at the following pictures.

- 12 - 6. Turntable-Decoder TT-DEC-R programming: • Important information: You can start with the first operation and with the programming only after completing all processes of the sections 1 to 5 of this manual. Setting the unit into operation without completing the processes described within section 1 to 5 of this manual can damage the Turntable-Decoder TT-DEC-R and your turntable. Please proceed with the programming during the fi ...

- 13 - Programming process: 1. Switch-on your digital-layout and the TurnTable-Decoder TT-DEC-R. If you want to perform the programming of the TT-DEC-R via your model railway software you have to switch-on those and adjust the turntable if required at first in accordance to the relevant instruction of the software. It is important that your model railway software supports the Märklin-turntable decoder 7686 because the TT-DEC-R is compa ...

Roco Drehscheibe 42615 Roco Turntable 42615 min. 4,5° page_1159 During the programming process please define one track connection as track 1 as a so-called reference track. Programming process: 1. Press 2-times shortly the key S1. The green LED flashes. 2. Send now the command >Input<. The red LED will switch off shortly and the turntab ...

- 15 - Test now the programming by sending the command >Turn<. If the bridge turns now by 180 degree is the programming successful. Programming sample: With reference to the programming process item 3 has the turntable bridge turned into the reference position. The bridge stops in level with the small house on the left side. With the command >Clear< will be the position track 1 (reference track) stored. (Programming process item 4). Wit ...

- 16 - 6.4. Bridge track polar reversal (only 2-conductor mode): This section is relevant only if you use your Roco turntable 42615 in 2-conductor mode. For using the 3-conductor mode (tracks with center conductor) is no bridge track polar reversal required. As described within section 3.3. (isolation of bridge track contacts) is a complete isolation between bridge track and track connections required. On this way all turntable tracks w ...

- 17 - At the right turntable section has the red digital cable always to be connected to the first rail if looking to the wiring in clockwise direction. If the turntable bridge is passing the parting-line between the two wiring sections the Turntable-Decoder TT-DEC-R will change the polarity of the bridge track provided that you programmed the parting-line. At the sample connection will be the parting-line on the track 4 because the po ...
