Connecting the KeerPlus3
Power Supply
The supply voltage that must be offered on the KeerPlus3 can be done in three different ways:
DC voltage 12-16 VDC
AC voltage 12-16 VAC
DCC Signal
The DCC signal means the Track Output of the control panel. The supply by a direct voltage supply is
preferred, however, because not everyone has it, it is also possible to use an AC transformer or the DCC
voltage. The module is not polarity sensitive, so it does not matter where you connect the plus and
minus.
DCC Signal
The figure shows the DCC input (2) to which you must connect the raw DCC voltage from your control
panel. In the base the left terminal is B and the right is terminal A. In the connection diagram we have
given the A a blue colour and the B a black colour.
Unfortunately, the output is not the same for every exchange, so you must experimentally discover which
order should be applied for you. Another variable is the way in which you have applied the polarity to
your lane.
If after connecting the Reverse loop you get a short circuit on your exchange as soon as a locomotive
enters the Reverse loop, that is an indication that you must switch the A and B connection on the
terminal 2 of your module.
