Open frame type Point motors
(usually fitted on the underside of the baseboard under the point)
Some open frame type point motors have 3 terminals or wires and some have 4. If your point motor
has 4 you will need to connect one of each of the coil terminals together as a common - see below.

Types of Point motors
There are two main types of solenoid point motors available; Surface mount types which mount on
top of the base board next to the point, and open frame type motors which fit beneath the
baseboard under the point. Although surface mount motors can be easier to fit, generally they are
not as powerful as the larger open frame type which fit under the baseboard. Whichever type of
point motor you choose make sure the point blades and actuator mechanisms all move smoothly
and freely. Note that although the DCC32 includes a built in CDU to give the coils a boost, this will
not be enough for a motor to overcome a tight or sticky mechanism. Note that the DCC32 is only
suitable for controlling solenoid type point motors, not the motorised ‘tortoise’ type.
Connect your point motor as follows - our examples all show connection to one motor and output
for clarity but the other outputs are connected in exactly the same way. Don’t forget to keep the
wires to the motors as short as possible and use thick cable to connect them. (We recommend
only one point motor should be connected to each output to ensure maximum power is available)
Surface Mount type Point Motors
Surface mounting point motors usually have 3 wires prefitted, one common wire and one for each
of the coils. Note that there is no standard colour code for point motors and they vary between
manufacturers so check the instructions which come with each motor carefully especially if using
more than one make! Eg Hornby and Peco use the same three colours but have different wiring!
