CHECKING AND REPLACING FUSES
Check fuses with a continuity measuring instrument (tester, ohmmeter, multimeter, etc.) as they may appear intact to
the eye even though they are electrically faulty. Every fuse must be replaced with another one of the same value (in
Amps) and type (rapid or delayed), as indicated in the manual.
There are 9 fuses on the Triax QUATTRO key-cutting machine.

2 fuses:
4 Amps delayed (230V) - 6,3 Amps delayed (100V) - 5 Amps delayed (120V)
Located on the power socket on the back of the machine,
next to the switch, these protect the machine from voltage
surges and possible short circuiting.
Check and replace if necessary, following these instructions:
1. Switch off the machine and disconnect the power
lead.
2. with the aid of a screwdriver open the socket flap,
remove the fuses and replace if necessary.


3 fuses: F2, F3, F4 :
F2: 6.3 Amps delayed
Protect the step motors and their electronic controls (+32V d.c.)
F3 4 Amps delayed
Protect the logic circuits for controlling the microprocessor circuit board (+5V d.c.)
F4 2 Amps delayed
Protect the digital outlet circuits for the low voltage controls and sensor inlets (+24V d.c.)
Situated on the electronic circuit board inside the base, they protect the circuit board from possible short circuiting.
Check and replace if necessary, following these instructions:
1. switch off the machine and disconnect the power lead.
2. remove the bottom metal plate.
Check the fuses and replace if necessary in the following way:
1. to remove the fuse:
use your fingers to press the cap on the fuse holder and turn anticlockwise.
2. to fit a new fuse:
take care that the fuse is properly positioned, press the cap on the fuse holder and turn clockwise.
