1General Safety
Safety
Considerations
Warnings and cautions are used throughout this manual. It is the
responsibilty of the the user to familiarize themselves with the meaning
of a warning before operating the particle sensor. Warnings may
appear in the left margin of the page next to the subject or step to which
it applies or within the step itself. Take extreme care when performing
any procedures preceded by or containing a warning.
There are several classifications of Warnings defined as follows:
WARNING: There are
no user-serviceable
components inside the
particle counter.
• LASER - pertaining to exposure to visible or invisible LASER
radiation.
• Electrostatic - pertaining to electrostatic discharge
• Network Connect - pertaining to communication ports and
instrument damage
LASER Safety
Information
This product is considered to be a Class 1 LASER product (as defined
by FDA 21 CFR, §1040.10) when used under normal operation and
maintenance. Service procedures on the sensor can result in exposure
to invisible radiation. Service should be performed only by factory-
authorized personnel.
The particle counter has been evaluated and tested in accordance with
EN 61010-1:2012, “Safety Requirements For Electrical Equipment for
Measurement, Control and Laboratory Use” and IEC 60825-1:2007,
“Safety of LASER Products”.
WARNING: The use
of controls, adjustments
or procedures other than
those specified within
this manual may result in
personal injury and/or
damage to this
instrument.

Electrostatic
Safety
Information
The following information is provided to prevent damage to
Lighthouse instruments or harm to humans.
WARNING: Using a
wrist-strap without an
isolation resistor will
increase the severity of
an electrical shock. Use
of controls or
adjustments or
performing procedures
other than those
specified herein may
result in hazardous
radiation exposure.
Electrostatic discharge (ESD) can damage or destroy electronic
components. Therefore, all service or maintenance work should be
done at a static-safe work station. A static-safe work station can be
created by doing the following:
• Use a grounded conductive table mat and resistor-isolated wrist-
strap combination
• Earth-ground all test instruments to prevent a buildup of static
charge

2Introduction
Overview This operating manual introduces the Lighthouse Liquid Particle
Counter REMOTE models RLPC 0.1m, RLPC 0.2μm, RLPC 0.3m
and RLPC 0.5μm. Included in this manual are instructions for
operation, communications and maintenance.
Description The RLPC 0.1m, RLPC 0.2μm, RLPC 0.3mand RLPC 0.5μmhave a
range of 0.1 - 0.5m, 0.2 - 2.0 m, 0.3 - 3.0 m and 0.5 - 5.0 m at a
sensitivity of 0.1 micron, 0.2 micron, 0.3 micron and 0.5 micron,
respectively, and the capability of real time continuous data collection
using the RS485 MODBUS protocol.
With a user-controlled flow rate of 100 ml/min., + 5%, the RLPC
sensors are designed to accurately measure up to 4 channels of
simultaneous particle counts in various liquids including solvents, acids
and bases (see Table 2-5 and Table 2-6 for chemical compatibilities).
.
Figure 2-1 The REMOTE Liquid Particle Counter
The instrument uses a laser diode light source and laser beam shaping
optics to illuminate a cross section of the liquid flow path. As particles
move through the flow cell, they enter the laser beam and scatter light.
The light scattered is collected by the optical system and imaged onto a

Lighthouse REMOTE Liquid Particle Counter (MODBUS Output) Operating Manual
2-2 248083227-1 Rev 8
photodiode. The photodiode converts the light into current which is
converted to voltage and amplified by the electronics.
The result is a voltage pulse each time a particle crosses the laser beam.
The width of the pulse is proportional to the time it takes the particle to
cross the laser beam and the pulse’s amplitude is proportional to the
size of the particle.
The voltage pulses created by the particles are processed by additional
electronics to quantify the pulses by the size of each particle. The
quantities of the various sized particles are processed and stored in the
sensor’s buffers or transferred via MODBUS.
The RLPC counters were created for continuous, 24 hours per day, 7
days per week operation. The instrument provides versatile mounting
options allowing installation where space is at a premium. The RLPC
integrates seamlessly with many large facility monitoring or
management systems and transfers up to 4 channels of simultaneous
particle count data using the RS485 MODBUS or RS485 MR Protocol
output.
Accessories Several accessories can be ordered to tailor the instrument to specific
needs. Contact a distributor for additional information and datasheets.
