6 Maintenance and Care
The product does not require maintenance. If cleaning is necessary, the product should only be
cleaned with a dry cloth or a brush to remove dust etc. Do not use aggressive cleaning agents or
chemical solutions.
7 Technical data
7.1 Operating Voltage and Current
The power supply (connections B and 0) of the device shall be the digital track voltage generated
by a digital control unit that is supplied from a transformer of max. 18 V AC or from a power supply
with max. 25 V DC.
The track segment connections (B1, B2, B3) maintain the digital track voltage when in driving state,
or a current-limited DC voltage when in braking state. The max. allowed current per track segment
is 2 A.
The max. sum of all track segment currents is 3 A.
The maximum relay switching capacity is 2 A current and 30 V DC or AC voltage.
7.2 Signal Input Control Voltage
The threshold of a control voltage applied to S1+ and S1– (equivalently to S3+ and S3–) is approx.
4,0 V. It depends to some extend on varying properties and tolerances of the corresponding opto-
coupler and resistor.
The maximum allowed voltage is 24 V AC or DC.
7.3 Track Segment Current Sensors
The occupancy of a track segment is sensed by a current detector. The threshold depends to some
extend on varying component (e. g. the optocoupler) properties and tolerances.
Typically, occupancy is detected if the resistance between B1 (or B2 or B3) and 0 is less than ap-
prox. 10 kΩ. This corresponds to a mimimum required current consumption by the loco of approx.
2 mA.
