Solution
Open the module containing the board (read chapter 9.3). Replace the LED
board that does not work with another one of the same module;
(a) if the latter works, replace the faulty LED board;
(b) if again it does not work, connect the cable of the LED board to another
connector of the control board (FC DRIVER).
- If the LED board works, replace the FC DRIVER
- If the LED board works, replace the cable.
Check the level set on the control Console.
If the module remains completely switched off when it is turned on, make
sure that:
(a) the connection of the module to the power supply module on the back of
the scoreboard is undamaged.
Connect the module to another cable coming out of the power supply
module.
(b) If the module lights up, replace the cable of the power supply module.
Open the module (read chapter 9.3) and:
(c) check that the connections are connected and undamaged;
(d) if the LED of the control board (FC DRIVER) is switched on, replace the
board (chapter 9.5).
Measure the voltage between the power supply terminals of the FC DRIVER
board (Fig. 7).
(e) Voltage > +20VDC  replace the FC DRIVER board (chapter 9.5).
(f) Voltage < +20VDC  replace the module cable.
If the module lights up for 1 second when it is turned on, but then remains
completely switched off, connect the module using another cable coming
out of the power supply module.
(g) If the module displays the information sent by the Console, replace the
cable of the power supply module.
Open the module (read chapter 9.3):
(h) check that the connections are undamaged;
(i) replace the FC DRIVER board (chapter 9.5).
Check that on the control Console:
(a) the volume is correctly set;
(b) the programmed sound duration is > 0.
Open the power supply module (read chapter 9.2). Disconnect the horn and
then feed it directly with +24VDC (we recommend the use of hearing
protection devices):
(c) if it works  replace the FC HUB board (chapter 9.6);
(d) if it does not work  replace the horn.
