5.2 FSM-CD300B Controller/Driver
The FSM-CD300B controller/driver establishes the feedback interface
between the angle position sensors and the drivers providing current to the
voice coils that tip and tilt the mirror assembly. It also provides an interface
between the user and mirror, allowing control voltages to be applied and
mirror positions to be ascertained.
The FSM-CD300B is equipped with a universal power supply that handles
100-240 V, 50/60 Hz. A standard power cord interface (IEC 950) facilitates
power plugs that are suitable for most European, North American, and Pacific
Rim Countries.
Figure 10. Removal of Fuse Block.
A fuse block is located above the power connector and utilizes two 5 x 20
mm slow-blow glass fuses rated 2.5 A, 250 Vac. To remove the fuse block,
first unplug the power cord, compress the two plastic tabs on the right and
left sides of the fuse block, and pull out the fuse block. No tools are needed.
When reinserting the fuse block, make sure that the alignment tab is at the
bottom.
WARNING
Dangerous voltages are present inside the FSM-CD300B controller/
driver when connected to AC line power. To avoid the possibility of
electrical shock, always unplug the unit from AC line power when
checking or changing fuses.
