Inspection & Test
1.1. Preventive Maintenance
Inspect and test the door sensitive edge
function daily and perform a complete
inspection every year or 100,000 miles
(160,000 km), whichever occurs first. Visually
inspect door sensitive edge for cuts,
tears, or other damage. Replace sensitive
edge if damaged.
❒ Inspect for properly connected tubing from
sensitive edge to pressure wave switch.
❒ Inspect electrical connections on pressure
wave switch.
❒ Perform a functional test on the sensitive
edge system as outlined in the following
Functional Test procedure
1.2. Functional Test
1. Ensure that the system is at full air pressure,
the vehicle is parked and the parking
brake is set
2. Open the doors to be checked.
3. Set the doors to close.
4. Standing outside the bus and while the
doors are closing, firmly pinch the sensitive
edge seal on the left hand door panel. The
doors should reopen. See “Fig. 1: Pinch
Test.
5. Repeat steps 3 and 4 for the right hand
door panel.
6. Standing outside the bus with the door
closing, hold a 1 inch diameter rod (hardwood
or metal approx. 18 in. (45.72 cm)
long) perpendicular to the side of the bus
at the vertical centerline of the door opening,
12 inches above the bottom of the
door panels. See “Fig. 2: Rod Test.
7. The doors should reopen when the door
edges contact the rod.
8. Repeat steps 6 and 7 two more times. First
with the rod held at the mid point of the
door opening and again with the rod held
at a point 12 inches below the top of the
door panels.
9. If the doors open when tested according to
steps 4 through 8, the sensitive edge system
is working properly.
10.IIf the doors fail to open at any testing step,
this may indicate a problem with a component
of the sensitive edge system (sensitive
edge seals, pressure wave switches,
tubing or connection point). Verify proper
operation of these components and then
repeat this test procedure.
