6.7.2. Wiring daylight signals and light bulbs or LEDs
If you use daylight signals with incandescent lamps (light bulbs)
or LEDs you must set the corresponding output to continuous
mode.
If the signal has incandescent lamps as shown for output 2 in
figure 5 you may wire the lamps directly to the terminals of the
SwitchPilot.
In order to limit the current for signals with LEDs a resistor must
be wired in series with the LEDs. This is shown for output 4 in
figure 5.
Please check if your signal already has a built-in resistor. Applying
power without this resistor will destroy the LEDs immediately!
If there is no resistor in place you must wire this resistor marked
“R” in series to the LEDs. Subject to the supply voltage and the
desired brightness of the signal the resistor should have a rating
of about 1 kohm to 2.2 kohm.
The screw terminal C of each output has positive potential.
Therefore the cathode of the LEDs must be connected to the
terminals Out A respectively Out B.
6.7.3. Wiring a motor drive
SwitchPilot Extension
The SwitchPilot can operate motor drives for turnouts with the
help of the SwitchPilot Extension. The direction of the motor is
reversed by changing the polarity of the voltage on the motor
terminals thus changing the position of the turnout or the aspect
of a semaphore signal.
Only use motor drives with limit stop contacts to avoid overheating
or a burnout of the motor. The relay outputs of the SwitchPilot
Extension always connect the supply voltage to the load.
A motor drive is wired as shown in figure 6. It will be energized
by the SwitchPilot.
Please take note of the permitted maximum supply voltage of
your motor drive as stated in its manual.
