(3) LEDs
The two LEDs indicate that the power supply is working properly. Once the A-100MBP is
connected to the external AC/AC adapter, both LEDs should come on. The upper LED is
the indicator for +12V, the lower for – 12V.
If both LEDs don' t come on, first of all check that mains power is available at the socket
which the A-100MBP power supply was connected to; then that the mains adaptor is
actually putting out voltages, and that a DC adaptor hasn' t been used by mistake instead of
the 12-15V AC type. If only one of the two control LED lights up probably by mistake a
power supply with DC output is used.
If the A-100MC is used please pay attention to these additional notes:
•
Move the mounting nuts inside the aluminium rails to positions that fit to the holes of
the module front panels. E.g. a small screwdriver or paper-clip may be used for it.
•
Place the module carefully into the space in the case, and fasten it firmly in place
with the supplied screws (M3x6).
•
Repeat this procedure until all modules (and possibly blind panels) are installed and
the front of the case is fully closed.
•
Now connect the A-100MC to the power supply
•
Test out the installed modules.
•
If it doesn' t seem to be working as expected, immediately disconnect the A-100MC
from the power supply.
•
In this case, double-check all connections, making completely sure that the ribbon
cables are the right way round where they connect to the bus (i.e. "RED STRIPE
DOWN").
•
When you' re installing extra modules, it may be necessary to take another module
or two out, to allow you easier access to the bus board.
Interconnecting modules
For connecting modules to each other, you need mono mini-jack ((∅ 3.5 mm) patch
leads. We offer patch leads in different lengths (from 15 cm to 2 m) and colors.
