FCS modules
English
Connection to the supply voltage
The module is designed for connecting to a supply voltage of 0,9 to
1,8 V (= one accumulator battery). If it is connected to a higher supply
voltage of 1,6 bis 2,5 V (= two accumulator batteries) you have to
reduce the input voltage by mounting a diode (e.g. 1N4148) in the
lead-in wire.
Connect the soldering point X1 to the positive pole and the soldering
point X2 to the negative pole of the accumulator batteries.
Caution:
The module should not be connected the wrong way
round. Otherwise it will be damaged when put into operation!
Connection of the diodes
Connect the LEDs´anodes (+) and cathodes (-), as in the connectioning
diagram, to the soldering points X3 and X4. The module is a constant-
current source, therefore the mounting of additional series resistors is
not necessary.
