seals. Fasten the control box using washers and two M6 bolts to a tightening
torque of 12Nm +/-3Nm.
Figure 9.1 DPF Soot Sensor Orientations
The Electronic control box has a maximum ambient operating temperature of
85
o
C and a minimum of –40
o
C. It must be mounted in a location where it will
not exceed these temperatures. The antennas are supplied screwed into the
DPF. They have been designed with heat sinks to shed enough heat so they
can withstand the 200
o
C skin temperature. The cables between the antennas
are high temperature coaxial cable. They are capable of surviving
temperatures up to 200
o
C.
The Soot sensor is designed to be mounted to a rigid member, such as a
major part of the machine structure. It should not be mounted too less rigid
members such as large sheet metal panels. Areas that are known to be
especially hostile should be avoided. Maximum vibration limits for the DPF
Soot sensor electronic box is 10Grms.
Coaxial cables should not have harsh bends or twists in them or it may
damage the internal conductor or insulator. The minimum wire bend radius
for this cable is 51mm. Any extra cable should be coiled, not bundled to
conform to the 51mm minimum wire bend radius. The coaxial cables require
connection to the Soot Sensor antenna housed within the DPF to a tightening
torque of 1.2Nm +/- 0.2Nm.
The Soot sensor must be fastened using M6 or 1/4” bolts and appropriate
washers. The installation torque is 12 Nm +/- 3 Nm.
This sensor currently uses a 6-pin, key 3 receptacle. The part number for the
mating connector is 281-8811 as shown in Figure 9.2 and table 9.1.
