Hi guys,
 
two weeks ago,during maintenance day, we replaced the WFD card on SM3
corresponding to the channel 36, which we supposed to be damaged.
Actually we believed that this card could involve all the other ones because
several zero suppression off signals frequently came out from that WFD card.
In fact, after having replaced it, now the zero suppression off number is much
lower than before (one or two events per run), that's fine.

A presto,

                                 Massimo
