Table 3.2 Safety interrupted outputs
Connector C8 goes to the Safety Stop circuit. This input is used to interrupt power to the motors in
case of collision, motion controller software fault, or if one of the E-Stop buttons is pressed.
The electronics within CardioMD, including the detectors, are operated on uninterruptible 55 V
DC. Local DC-DC converters internal to the electronic modules convert the 55 V DC supply
voltage to the voltage levels used internally (i.e., 3.3 V DC, +/– 5 V DC, 12 V DC, +/– 15 V DC
and HV).
The AC power supply contains a number of fuses. The access and location of these fuses are
indicated in Figure 3.6 on page 3-6. The electrical location of the fuses is shown in Figure 3.7
below.
