The DO-160 NORMAL screen has the following tests:
• VOLT MIN
• VOLT MAX
• VOLT UNDER
• VOLT SURGE
• POWER INTERRUPT
The above tests can be selected by scrolling to the highlighted selection using
the up and down key and the ENTER key to start the selected test. For some of
these tests, numeric data entry may be required to define the test number or
the modulation rate.
VOLT MIN
RTCA 22.0 22.0 11.0
EUROCAE 22.0 25.1 12.5
Table 9-13: Normal Voltage Minimum
This test will change the output voltage from 28V or 14V to 22V or 11V. The
test will last for 30 minutes. The ← (backspace) will terminate the test at any
time.
VOLT MAX
RTCA 30.3 30.3 15.1
EUROCAE 30.3 29.3 14.6
Table 9-14: Normal Voltage Maximum
This test will change the output voltage from 28V or 14V to 30.3V or 15.1V.
The test will last for 30 minutes. The ← (backspace) will terminate the test at
any time.
VOLT UNDER
This test applies to category Z and 28-volt category B equipment. The output
voltage will drop to 10 volts and will ramp up at a rate of 0.15 volt/sec for the
US standard and at a rate of 0.30 volt/sec for EUROCAE standard for 30
seconds before it returns to nominal value.
VOLT SURGE
This test will surge and sag the voltage to a level and duration specified Table
9-15 with 5 seconds between transients. The test is repeated three times.
A 40 40 30 15 17 30
B 40 40 30 15 17 30
