Air System Self-Diagnostic Test
This self-diagnostic test enables the bed to automatically check the operation
of the drive circuitry for the air manifold valves, flow direction valve, and
pump. This only tests for power being switched to each valve or pump
component to determine if a possible fuse has failed or other power failure. It
does not test for current flow through any valve or pump.
1. To conduct this test, the bed’s motor power must be off—Motor Power Off
LED on the footboard control panel is illuminated (see figure 2-2 on page
2-10). Press the All Motors switch (A) to deactivate the motor power if
necessary (see figure 2-3 on page 2-13).
2. To activate the air system self diagnostic test:
• Press and hold the bed down and auto firm switches simultaneously for 5
seconds (see figure 2-5 on page 2-15).

3. Confirm which circuits have passed or failed in table 2-3 on page 2-16 by
observing the surface power LED and the corresponding footboard LED.
NOTE:
While the test is being done, the surface power LED and the corresponding
footboard LED of that component will be flashing. When the test is complete,
the footboard LEDs that correspond with each drive circuit will either remain
on or flash. Since there are more items to test than available LED’s, the results
will be displayed in two passes. The surface power LED will determine which
pass is being displayed. If it is flashing, it is pass 1, and if it is on (steady), it is
pass 2. The circuits that pass the test will light their corresponding LED steady
