Accessory decoder LS150 9
Connecting motorized switch machines
Please see Figure 1 (Page 7), top right:
Motorized drives (such as Kato Unitrak, and Circuitron Tortoise)
normally require DC voltage for operation. By reversing this DC
voltage, the direction of rotation of the motor is changed and thus
the turnout is set to a different position.
In order to be able to turnout drives like those described with the
LS150, you need to add 2 simple rectifier diodes. Connect the
switch machine as shown in Figure 1 (Page 7).
The type of diodes you can use depends on the
power consumption of the switch machine.
Normally diodes of the type 1N4001 should be
sufficient. (Radio Shack part # 276-1101)
The position of the cathode can be seen by the
ring on the diode.
You may have to extend the pulse duration of the output used for
motorized switch machines to fully move the points to the
respective end position, For more detailed information, please
refer to the Section "Setting individual addresses and pulse
duration".
The use of the LA010 adapter is not required for the
operation of motorized drives. Moreover, this adapter
must not be connected to the LS150!
The motorized point drive from the company Pilz is connected
exactly like a double-coil point drive; no additional diodes are
required:
Connection to LS150: + C -
