Introduction
A diesel particulate filter (DPF) is used to reduce the exhaust particulate matter emitted by an engine. By
definition, the DPF accumulates the particulate matter (soot) and oxidizes it with a passive, active, or combined
strategy.
Diesel engines are sensitive to backpressure created by any restriction in the exhaust flow. When a DPF
is used, the backpressure varies depending on the soot loading in the filter. The filter will fill up with soot and ash
over time and periodically require cleaning. As a result, a backpressure monitor is used to inform the vehicle operator that the filter needs cleaning.
Monitoring exhaust backpressure is also a useful way to identify the condition of the engine. Increased
soot levels from the engine will cause the filter to load faster. Identifying this trend allows the service technician
to correct engine problems before they become severe. Backpressure monitoring can also indicate DPF overloading and/or slow soot combustion.
Engine Control Systems is pleased to offer a DPF Backpressure Monitor & Logger with features to protect both your engine and your DPF. The Backpressure Monitor & Logger will be referred to as the BPM throughout this manual.

Understanding the BPM Connections
Figure 1 - Backpressure Monitor & logger (BPM)
POWER
Connects to continuous vehicle battery power. The BPM will operate with a 12V or 24V power source.
DATA
Connects to the PC for setup and data downloading.
REGEN
Connects to the junction box on Purifilter Plus systems only. The BPM can monitor the regeneration status when
connected.
REMOTE
Connects to the Remote Driver Display.
TC
Connects to the K-Type thermocouple that measures the exhaust temperature.
PRESSURE
Connects to the pressure line that samples the exhaust stream backpressure
Use caution when plugging in the cables. Make sure
the pins are aligned properly before pushing in the
connector.
