6.4.2 Voltage Sensors
The CMC monitors the following DC voltages: +12V, -12V, +5V,
+3.3V, Battery Output. By default, voltage sensors will trigger major
alarms when their threshold limits are exceeded.
The CMC also monitors the input voltage on the input modules.
Note that in a chassis that uses AC power, the thresholds reflect the
fact that the AC input modules will accept AC power between 90 and
260 volts. No alarm is triggered at abnormal voltages like 180.
*Volt sensors 5 and 6 monitor the input voltage to the power input
modules.
The accuracy for the above voltages is shown in the following table.
Please see Table 6-1 for information about the normal ranges and
thresholds associated with them:
