Z21 ® Multi Loop Assembly - Roco and Fleischmann Z21 multi LOOP Manuel D'utilisation

▪ As an alternative, the module can also be used via the short circuit detection. This has the advantage
that fewer separating points and less cabling is necessary but this also results in the wheels and
tracks being subjected to increased material wear.
▪ A mixed operation with sensor tracks and short circuit detection is available. In case a sensor track
does not work properly due to contaminated or corroded tracks, the short circuit detection will pro-
vide a correct operation at all times. The short circuit detection may be turned on/off with a button
inside the module.
▪ A reliable operation of the module is guaranteed at all times as two separate switching relais are
utilized. Even if a train bridges a disconnecting point when the system is switched on, the module will
adjust to the correct polarization. In this case the loop section will be powered up with a slight delay
to the main layout.
▪ The module may be operated in analog layouts as well, utilizing an additional separate power supply.
