Power Supply and Voltage Distribution In the NARKOMED 2C, +5VDC, +12VDC and -12VDC are supplied to J15 on the processor board; +8VDC is supplied to J4 on the alarm channel and is also distributed to the ventilator controller via J3 on the alarm channel. These voltages can be measured at the connectors shown in Figure 3-1.
Troubleshooting Guides Table 3-2 lists common failure modes and symptoms (excluding simultaneous multiple faults) for the monitoring and display devices in the NARKOMED 2C. Each failure mode or symptom is keyed to a troubleshooting guide flow chart at the back of this section to assist the TSR in locating a problem. These flow charts assume that the machine is plugged into an AC outlet with the correct voltage, and the machine is not running on its backup battery.
