Basic functions of the module
The reverse loop module features several operating modes:
 With additional sensor tracks installed, the module operates without any short circuits. The reverse
loop module detects the polarisation of the entering train and adjusts the polarity of the reversing
loop section accordingly before the train enters the loop.
 Alternatively the module may be used with the common short circuit detection. This requires less
wiring however the burn-off on the wheels and the track is increased significantly.
 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-
GB
vide a correct operation at all times. The short circuit detection may be turned on/off with a jumper
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.
However, in analog operation no train must bridge a disconnecting point when the system is swit-
ched on.
 The module must only be connected to components described in this manual. Connecting this unit
to other components even if the plugs are matching may result in serious damage to the module or
other components.
 Delivery status: Jumper opened for Short circuit-detection
 This module is not a toy!
