Fuse Changing
The fuse protects the unit from power overload. If the TomoScan FOCUS LT
instrument does not turn on when properly supplied by an AC power source, verify
the fuse located in the power entry module on the back panel.
The internal power supply units of the instrument have protective fuses that are not
replaceable by an operator. If these fuses are defective, please refer to a qualified
technician for replacement.
To change the fuse
1.
Ensure that the instrument is turned off and the AC power cord is disconnected
from the back panel of the instrument.
To prevent the risk of an electric shock, first disconnect the power cord from the
power outlet, and then disconnect the power cord from the instrument.
The fuse in the power entry module is used only when the TomoScan FOCUS LT is
powered by an AC source. When using a DC power source, overload protection is
provided by internal voltage limiters inside the instrument.
2.
Using a flat-blade screwdriver, pull out the fuse holder located on the back panel
(see Figure 4-2 on page 39).
3.
Remove the fuse from the fuse holder.
