2. Pretest Procedures
Before performing any of the tests below, examine the B-600 testing system. Check the
electrical connections between the electronic unit, the light source and the horn to be
sure they are properly made. Turn the electronics unit and the light source ON and
observe that the Power-On lamps light. On a regular basis, check the equipment to be
sure nothing blocks the exhaust vents on the light source.
All of the testing procedures below assume that the test equipment is ON and is in good
working order.
In the procedures which follow, whenever reference is made to a particular control or
indicator, you may assume that the location is on the B-600 Electronics Unit. If it is not,
the procedure will indicate where the control or indicator is located. Also, unless other-
wise indicated, the Horn/Pack Simulator switch should be at HORN; the CAL/Test
switch should be at TEST; the Norm/Midcycle switch should be at NORM.
One other word. You must remember that every time you install the camera on the horn,
you must press the MANUAL RESET button on the electronics unit to be certain that
the electronic circuitry is cleared for the particular test you are doing. This applies even
in the middle of a procedure where the camera must be removed from the horn and then
re-installed. REMEMBER - PRESS THE MANUAL RESET BUTTON WHEN
YOU PLACE THE CAMERA ON THE HORN!
