ESD PROTECTION
Potential Damages Caused by Exposure to ESD
To prevent electrostatic discharge (ESD) damage to LectroCount register electronic components, all LectroCount
electronic register truck intallations are required to properly ground truck seat(s) cushions and Epson printers.
Prolonged exposure to ESD over weeks, months, or years can corrupt LectroCount registers’ CPU memory and
damage the electronic components in LectroCount registers (as well as other electrical components in the truck’s
electrical system).
Adjustable, shock-absorbing seats, if not grounded correctly, generate signicant amounts of ESD. The pivots and
hinges of these seats isolate the seat cushion from an electrical ground. Without an electrical ground, ESD builds
between the seat cushion and the operator. This built-up ESD can be transferred back to the LectroCount register
from any point of the truck’s electrical system, such as the cabling from the LectroCount register to the cab or the
Epson printer.
Liquid Controls’ Grounding Kits
To protect electronic components from ESD, all LectroCount truck intallations must include the installation of the
LectroCount Ground Strap Kit (PN 82185) and the Epson Printer Ground Wire Kit (PN 82184). Properly grounded
seats allow static electricity to “bleed off” the driver and the seat before it can build up, discharge, and damage the
LectroCount register or any of the truck’s other electrical components.
The LectroCount Ground Strap Kit will be included with all future LCR 600 LectroCount register shipments, and the
Epson Printer Ground Wire Kit will be included with all future Epson printer cable kit shipments. Effected part numbers
are listed below. For existing installations and previously purchased LectroCount registers and Epson printers, both
ground kits are available from LC.
ESD Procedural Precautions and LectroCount Register Grounding
Installation Notes
When installing or performing maintenance on a LectroCount register, there are certain guidelines that must be
followed to safeguard against ESD damage.
REGISTERS NOT MOUNTED DIRECTLY TO THE METER
In typical LectroCount installations where the LectroCount register is mounted directly to the meter, the LectroCount
housing is grounded through the meter. If the register is not mounted on the meter, you must make sure the
LectroCount housing is grounded properly.
Alternate grounding method
Connect the green ground screw (inside the LectroCount housing in the upper right corner) to a known good ground (less than
1 ohm). Use a 12ga. or larger stranded wire.
FIXED INSTALLATIONS
LectroCount housings directly mounted to the meter are attached to the earth ground through the meter via the tank
and the tank piping ,which is grounded by the electrical system grounding rods. Division 1 xed installations typically
require metal conduit to the conduit hubs for the wiring. The metal conduit provides the necessary ESD protection.
Divison 2 installations can ground the LectroCount housing by using shielded cables (or wiring) run through liquidtite
(metal/rubber coated). The liquidtite and the liquidtite connectors provide the necessary ESD protection. AC xed
installations require and additional grounding method to ensure a proper ground.
Connect the green ground screw (inside the LectroCount housing in the upper right corner) to a known good ground (less than
1 ohm). Use a 12ga. or larger stranded wire.
. ESD Precaution .
Opening LectroCount Registers
Follow this procedure each time you open a LectroCount register or approach a LectroCount register with the door open.
Before opening the LectroCount register and handling the CPU board, it is important to discharge any ESD that may have built up on
your person. To discharge ESD from your person, touch a well-grounded point such as the LectroCount register housing, the meter,
the truck piping, or the bumper. When the maintenance is complete and the LectroCount register door is closed, the CPU board is
4
protected from ESD by the LectroCount register housing which is grounded to the chassis.

LectroCount LCR 600 Overview
OVERVIEW
GENERAL INFORMATION
The Liquid Controls LectroCount LCR 600 is a
microprocessor-based electronic meter register that
can be used for Weights & Measures approved custody
transfer actions in mobile or xed installations. The LCR
600 can control a meter system as a stand-alone unit,
or it can be used as a slave to a host controller such
as a process controller or an in-cab data management
system. The LCR 600 is a self-contained unit. All
operation, setup, and conguration functions can be
carried out using the LCR 600s red selector switch and
the alphanumeric keypad. No lap pads, laptops, or other
data entry devices are required. A seperate software
program for PCs, EZCommand, is available to congure
LCR 600s using a laptop computer.
INPUTS
In order to calculate ow measurements from a positive
displacement meter, the LCR 600 receives a pulse input
from an internally mounted quadrature pulser that is
mechanically connected to the ow meter (retrot kits
are available for installation onto Neptune, Brooks, and
Smith positive displacement meters). This pulse output
can also come from a Liquid Controls external POD
pulser or another pulse generator. In addition to the
pulse input, the LCR 600 is equipped with an input for
a temperature probe, so the register can compensate
volume measurements according to the temperature of
the product.
DISPLAY
The display is backlit, transective 5.7” QVGA display. It
is legible in direct sunlight and at night.
ALPHANUMERIC KEYPAD
The LCR 600’s alphanumeric keypad consists of 14
domed keys. The keys collapse and pop up to give a
tactile, positive conrmation of keystrokes. The keypad’s
multitap functionality allow users to input up to four
characters with one key.
SELECTOR SWITCH
The selector switch controls basic stop, run, print and
shift print delivery functions. To perform calibration
functions the cover plate must be removed and the
selector switch turned to the six o’clock position.
BASIC FUNCTIONS
• Calibration (single and multipoint)
• Weights & Measures custody transfer
(product delivery and ticket generation)
• Metrological data collection
• Presetting by volume

OVERVIEW
Meter System Components
METER SYSTEM
A Liquid Controls meter system not only accurately
measures product, it also regulates and puries product
ow in order to produce the optimal conditions for
measurement. Optimal systems typically include an air/
vapor eliminator, strainer, meter, register, and control
valve. The LectroCount LCR 600, a register, serves
as the central controller of the meter system. Most
components in the meter system are hard wired to the
LCR 600 via data communication cables. See manual
M100-10.
AIR/VAPOR ELIMINATORS
Air and vapor eliminators sense and remove air or
vapor in the piping before it enters the metering system,
ensuring that only liquid will pass through the meter for
measurement. Mechanical air eliminators do not require
a data connection to the LectroCount LCR 600 (in LPG
applications, they are often plumbed to a 3-way solenoid
which is wired to the LectroCount LCR 600). Optical air
eliminators use an optical sensor to monitor liquid levels
and a solenoid-actuated valve to turn the vapor vent on
and off. The optical sensor and the solenoid valve are
connected to the LectroCount LCR 600 by separate data
cables. See manuals M300-20 and M300-21.

VALVES
Valves control the ow through a metering system. They
open the line to initiate custody transfers and close the
line to stop custody transfers. Some valves can partially
close, slowing the ow rate to a dwell ow on preset
deliveries. By slowing the ow rate, valves can lessen
the hydraulic shock incurred by the meter system upon
shut off and provide accurate preset deliveries. Many
valves use solenoid-operated valves that require a hard
wired data connection to the LectroCount LCR 600. See
manuals M400-40 and M400-11.
ELECTRONIC TEMPERATURE VOLUME
COMPENSATION (ETVC) KIT
In order to perform temperature compensation
equations, the LectroCount LCR 600 relies on a
temperature probe inserted into the strainer housing.
Installation directions for the ETVC kit are included in
this manual.
LECTROCOUNT REMOTE DISPLAY
The 2¼" digits on the Liquid Controls LectroCount
Remote Display allow operators to view the register
totalizer values from distances of up to 100 feet. Hard
wire data communication with the LectroCount LCR 600
is required. See manual EM100-13.

Epson Slip Printer
POD Pulser
Epson Roll Printer
OVERVIEW
Meter System Components
PRINTERS
Printers print delivery tickets to provide a physical record
of custody transfers. The Epson slip printer is considered
the industry standard for many applications. Multi-
layered tickets are available to provide a physical record
for both customers and business records. The Epson roll
printer is ideal for recording multiple custody transfers
over an extended time frame.
PULSE OUTPUT DEVICE
The Liquid Controls Pulse Output Device (POD pulser)
converts the rotary motion of a positive displacement
owmeter into electronic pulses. POD pulsers can be
used in place of an internal pulser. They are ideal for
applications that require explosion proof components in
which the LectroCount LCR 600 register is installed at a
distance from the meter. The POD pulser requires hard
wired data communication with the LectroCount LCR
600. See manual EM300-10.
∆P Transducer
DMS i1000
EZCommand, Cable, and Adapter
The differential pressure transducer, common in
aviation applications, monitors the differential pressure
(pressure drop) across a full ow fuel monitor/water
coalescer. The highest differential pressure reached
during the custody transfer will then be printed on the
ticket. Using interlocks, the LectroCount LCR 600 can
shut down a custody transfer if the differential pressure
meets a preprogrammed differential pressure shutdown
value. The ∆P Transducer requires hard wired data
communication with the LectroCount LCR 600. See
manual EM300-40.
DATA MANAGEMENT SYSTEMS
The DMS i1000 is an in-cab computer with a heavy duty
lap pad interface. The DMS i1000 streamlines the ow of
data between the LCR 600 and back ofce accounting
software. The DMS i1000 must be hard wired to the
LectroCount LCR 600. See manuals EM200-10 and
EM200-11.
EZCOMMAND
EZCommand is Windows®-based interface that saves
and distributes LectroCount LCR 600 settings and
updates. EZCommand can be loaded onto a laptop.
Using a lap pad adapter (PN 81514) and a printer
extension cable (PN 71237), the lap top can be quickly
connected to upload settings and updates in the eld.
A ash cable (PN 81885), a data cable with a terminal
block (J3) on one side and a 9-pin connector for your
PC, can also make the connection but requires opening
the LCR 600.
