B - Inlet fuse for electronic rack
"1 amp - delayed'
When this fuse cuts out the two green leds (+5 Volt dc and + 12 Volt dc) on the UNIPOW 50 supply
module on the electronic rack go off, the display shows nothing, there is no response to any control
key and there is no communication with the computer.
C - X and Y axes step motor protection fuse
"4 amp - delayed"
When this fuse cuts out the relevant green led for the ST2DRV electronic module goes off and the
X and Y axes carriages will not move.
To replace this fuse, remove the 1st ST2DRV module from the rack (chap. 9.6, page 41). Remove
the four screws (V1) in order to separate the top part (V) of the dissipator and gain access to fuse
C on the circuit board (fig. 30).
N.B.: after replacing the fuse, fit the dissipator (V) securing the locking screws (V1) tightly to
ensure good heat conductivity between the parts in contact (fig. 30).

To replace this fuse, remove the 2nd ST2DRV module from the rack (chap. 9.7, page 42). Remove
the four screws (V1) in order to separate the top part of the dissipator and gain access to the fuse
on the circuit board (fig. 30).
N.B.: after replacing the fuse, fit the dissipator (V), securing the locking screws (V1) tightly to
