Introduction - ECM pmCAN Module Instruction Manual

Introduction

The pmCAN module kit is a compact PM (particulate matter) measurement device for use on
internal-combustion engines. The PM sensor looks like a spark plug, is screwed into the
engine's exhaust pipe, and operates on a charge-transfer mechanism explained in the section
"How the PM Sensor Works". The specifications for the kit are as follows:
Ranges: PM (Mass): 0.05 to 100 (Units: mg/m3)
PN (Number): 0.24 to 480 (Units: millions/cc (M/cc), ex. 0.24 M/cc is 240,000 #/cc)
Accuracy: ±10%. Increased accuracy via user-entered delta tables.
PM Sensor Mounting: 18mm x 1.5mm thread, 22mm hex,
Sensor must be mounted pointing down and finger tight.
Maximum Exhaust Temperature for Sensor: 500 °C, 932 °F
Temperature Range for Electronic Module: -55 to 100 ⁰C
Temperature Range for Cables: -55 to 220 ⁰C
Minimum Bending Radii for Sensor Cable and Extension Cables: 100 mm
Module: 114 mm x 120 mm x 35 mm, 540 gm, Sealing Class IP27
Communication: CANopen, Programmable Baud Rate, Programmable Node ID
Power: 6 to 32 VDC, 0.14 A @ 12 V

pmCAN kits are normally supplied with a PM sensor P/N 06-10T which has been designed
for tailpipe applications. A PM sensor P/N 06-10E can be optionally supplied which has
been designed for diesel engine-out applications. P/N 06-10E is less likely to foul but has a
longer seeding time which may not matter for diesel engine-out applications where the PM
levels are higher.
Setup of the pmCAN kit is performed using the supplied PC software program called the
"Configuration Tool". The Configuration Tool requires a CAN communication device to
communicate with one or more ECM CAN modules (ex. pmCAN, LambdaCAN*,
NOxCAN*, NH CAN, baroCAN, appsCAN) or analyzers (ex. NOx 5210, Lambda 5220,
3
EGR 5230, NH 5250, miniSOOT 5260). While the tool is being used with modules, just
3
ECM modules set to stand-alone mode (see Appendix B) should be connected to the CAN
bus. While the tool is being used with analyzers, just analyzers should be connected to the
CAN bus. With analyzers, the Configuration Tool is just used to produce .dbc files.
However with modules, the Configuration Tool replaces the analyzer's display head as the
user interface so it must do much more. This document focuses on using the Configuration
Tool with ECM's pmCAN module.
The Configuration Tool supports four CAN communication devices: Kvaser, ETAS, Peak
USB-to-CAN adapters, and the VectorCAN CAN adapter card. The latest driver software for
one of these adapters must be installed prior to using the Configuration Tool. This software
