Check to see if the beam up solenoid (4) is functioning properly. Check
the red LED on the solenoid itself (see Figure 5-16) to see if it turns on
during the test. Use a small hex wrench to depress the manual test button
on the side of the solenoid to see if the beam rises. If it does not move up,
check the air pressure or check for leaks in the air line. Replace the
solenoid if necessary.
