SECTION 4:

INSTALLING THE ELECTRONICS

Both the Encoder and Mimic Panel Controllers need mounting to the reverse of the fascia panel, but raising from the surface by about 25mm. I glue offcuts of MDF together with contact adhesive to form spacers. They need to be the width of both units (20mm).

To decide where these two units are going to be placed, fit one spacer block to each end of the two control boards, and move them around to see where they fit best, ensuring that they don’t foul any of the LEDS and switches. When you’re happy, mark the position and glue the spacers (Fig 9).

You should now have a panel with the LED and switches fitted along with the two control boards. Now it’s time to start connecting the wires.

The Encoder has 12 terminals for the point switches, and each terminal is split for the three wires – left, common and right. The centre wire goes to the terminal marked C and the two outer wires to the L/R respectively.

The LEDS need to be connected to the mimic control board. Make sure that Switch 1’s LEDS go to the correct output. Don’t worry at this stage if the LEDS are not in the correct position in the output as we can change these later (Fig 10).

If you have a crossover where one switch controls two point motors using the same address, you’ll need to use an MY3 adapter for the three LEDS. As with the encoder and mimic control panel, no soldering is necessary (Fig 11).

Your front fascia is now complete. Secure it to your box frame and then screw the frame in place.
