The DPM Reader is not intrinsically safe. Do not operate or maintain the DPM Reader
in any environments classified as hazardous as it may ignite flammable gases. The
Reader contains a single internally mounted Lithium Iron Phosphate battery pack with
a rating of 12.8VDC 6.4AH (81.9WH).
Any devices that connect to the data ports must comply with clause 4.7 of AS/NZS
60950.1.
2.2 Mains Voltage
All electrical work should be carried out in accordance with the state, federal or
applicable national electrical wiring codes and regulations.
The AC Mains electrical point into which the reader is to be connected, must have been
installed by a qualified electrician. The provided AC mains cable with special connector
interface for termination into the enclosure is one (1) meter in length and therefore we
recommend that the power socket dedicated to the DPM Reader should be installed
within 500mm of the left-hand side of theenclosure. The socket should be wired through
a suitable circuit breaker via an RCD device.
Two labelled isolation switches are provided on the left-hand side of the DPM Reader.
One is to isolate the AC mains, the other is to isolate the internal battery DC source
during service or whilst being transported. An additional LED illuminated low profile
power switch is located on the same side as the isolator switches, labelled POWER
which powers the internally mounted PLC and electronics.
Access into the DPM Reader is intended for suitable electrically qualified service
personal ONLY. Although an access key is provided with the DPM DPMRA01.A Reader,
there is no requirement to open the hinged door on the reader whilst installing the

3 System Overview
The PINSSAR DPM Reader DPMRA01.A is a stationary/fixed position near-real time
diesel emission monitoring apparatus.
The DPM Reader uses a laser light scattering photometer to measure the concentration
of diesel particles in a known volume of air. The reader enclosure is designed to be
vertically mounted on a flat surface such as a wall.
Built into a 316-grade sloping roof stainless steel enclosure 655mm in height, 600mm
in width and 252.5mm in depth with front door access for serviceability, the DPM Reader
is built for indoor operation in road/rail tunnel, loco/bus/plant/heavy vehicle service
depots, and underground mining environments.
The measured sample air intake is located at the bottom of the enclosure. Although
diesel particulate concentration levels may vary slightly with respect to height, we
recommend the enclosure is mounted at least 1 meter (from the bottom of the enclosure)
above the ground level to reduce proximity to dust on floors and general grime. This
also facilitates ease of serviceability.
The reader emission concentration measurements can be sent real time to a server via
an IP Network for evaluation and storing.
An Ethernet socket located on the left-hand side of the Reader facilitates connectivity
to a wired LAN, alternatively wireless connectivity can be provided wireless router and
antenna, which is configurable for Wi-Fi or cellular wireless networks.
The DPM Reader operates in measurement cycles.
The measurement cycle draws external air through a cyclone filter which filters
particulates in terms of size. The sample air is then heated to vaporise lower levels of
moisture and then passed through the measurement chamber.
Each measurement cycle is then followed by a clean air (particle free) flush through the
sampling air lines and measurement chamber where a reference zero reading is
obtained.
This data is fed into the on-board PLC and then communicated to a server via a
nominated IP network.
The DPMRA01.A is built on three essential stages. Power, PLC and the Measurement
stage. An overview of these stages is illustrated in Figure 1.
The Power stage includes AC and DC Power isolation switches, AC to DC conversion,
on board Battery Management System and DC power to the respective electronic
control and measurement circuits including the PLC and Wireless Router.

PIN-M-02 DPMRA01.A Service Manual
Copyright © Pinssar (Aust) Pty Ltd 2019. The PINSSAR logo is a registered trademark of Pinssar Pty Ltd
Page 12 of 96
The PLC stage is configured to control all the required analogue and digital inputs and
outputs to and from the measurement and control circuitry. Collected measurement data
is then collated and communicated via either the Ethernet socket or Wireless Router.
The Measurement stage controls airflow and its alternative paths, powers the laser and
measures outputs from the light sensor amplifier.
