Dip-Switches configurations
Dip 1 Dip 2 Dip 3
OFF OFF OFF
- FIRING MODE: ZC, BF, HSC, PA
- HB DIAGNOSTIC AVAILABLE: Partial and total load failure of each single leg
FAST FUSE needed only for controller without option "F"
See table Fuse/Fuseholders
NOTE: Take care about the "F4/N" connection (see the picture)
The wire "F4/N" is required always (also if Load 4 is not used)
