1. FLEXIBLE CONDUIT
1.1. Installation
The following procedure describes the
routing requirements of the flexible conduit
used between the door panel and baseplate.
The sensitive edge PVC tubing and
CLASS sensor wiring (if equipped) are
routed from leading edge of each door
panel, upward through the hollow shaft of
the roller bracket, and inward along the
baseplate. The PVC tubes terminate at
their respective pressure wave switch and
the CLASS sensor wiring (if equipped) terminates
at the CLASS controller, located
above the baseplate. The PVC tube and
wiring harness are protected with a spiral
wrapped loom.
Inspect the flexible conduit for proper
installation and routing as follows:
1. Close the door panels and feed the flexible
conduit from each door panel upward
through the shaft of their respective roller
bracket, being careful not to pinch or otherwise
damage the conduit.
2. Locate the P-clamp on the baseplate and
insert a short piece of foam tape inside the
P-clamp. Refer to your New Flyer Parts
Manual for part number of foam tape.
3. Route the flexible conduit on the forward
door panel through the P-clamp. Position
the P-clamp perpendicular to the baseplate
door channel and torque the clamp to
13 in-lbs.
Route the flexible conduit on the aft door
panel through the P-clamp. Position the
P-clamp at approximately 30° to the baseplate
door channel and torque the clamp to
13 in-lbs. See “Fig. 1: Flexible Conduit
Routing” on page 3.
Nylon tywraps must be applied over the
spiral wrap and not directly on the tubing
or wiring harness itself. DO NOT
over-tighten the nylon tywrap as this
could constrict the sensitive edge tubing
and prevent proper operation of the
sensitive edge system.

4. Carefully route the remaining cable assembly
to next closest and convenient tywrap
mounting clip on the baseplate. Route the
cable assembly to avoid potential contact
with moving parts or sharp edges. Secure
conduit to mounting clips with nylon
tywraps.
5. Connect the sensitive edge tubing from
each door panel to its respective pressure
wave switch.
6. Connect the CLASS sensor wiring (if
equipped) from each door panel to their
respective connectors on the CLASS controller.
7. Manually operate both door panels and
observe the movement of the flexible conduit
as the doors open and close. Verify
that the conduit does not kink or snag at
any point throughout their range of travel.
Light cable contact with the baseplate or
vehicle structure at the extreme ends of
travel is acceptable. If necessary, adjust
the orientation of the conduit and P-clamps
to ensure these requirements are met.
8. Upon completion of flexible conduit installation:
a. Test the function of the sensitive edge
system. Refer to Section 16 in your
New Flyer Service Manual for test procedure.
b. Test the function of the CLASS system
(if equipped). Refer to Section 16 in
your New Flyer Service Manual for test
procedure.
