accordance with the requirements of the authority having jurisdiction.
To comply with UL Listing requirements, Class 2 power supply, or an isolation power
source and overcurrent protective
device rated 5 Amp max, are required to be installed in the field. (Pour être conforme aux
exigences UL, une alimentation
électrique de classe 2 ou une alimentation électrique isolée et comportant un dispositif de
protection contre la surtension
de 5 ampères ou moins sont requises pour l’installation.)
Peripheral equipment must be suitable for the hazardous location where it is installed.
(L’équipement périphérique doit être adapté des endroits dangereux où il est installé.)

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 significant 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.

Introduction
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 12 gauge 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
fixed 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 fixed installations require and additional grounding method to ensure a proper
ground.
Alternate grounding method for AC fixed installations
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
protected from ESD by the LectroCount register housing which is grounded to the chassis.

LectroCount LCR 600 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 fixed 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 configuration 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 separate software program for PCs, EZCommand, is available to configure LCR 600s.
INPUTS
In order to calculate flow 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 flow meter
(retrofit 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.
OUTPUTS
The LCR 600 is equipped with a scaled pulse output, two auxiliary outputs, and two solenoids outputs.
These outputs allow the LCR 600 to communicate with meter system accessories such as solenoid-
controlled valves, optical air and vapor eliminators, remote displays, printers, and third-party devices.
COMMUNICATIONS
The LCR 600 is capable of interfacing in RS-232 and RS- 485 communication protocols.
HOUSING
The LectroCount LCR 600 housing and base are aluminum die cast and powder coated. The hinge door
design provides easy access to the internal connections and a Weights and Measures sealable fastener
opposite the hinges. There are seven machined ports, five ½” NPT ports and two ¾” NPT ports, on the
back of the LectroCount LCR 600 to provide secure cable connections for all external devices.
DISPLAY
The display is backlit, transflective 5.7” QVGA display. It is legible in direct sunlight and at night.
ALPHANUMERIC KEYPAD
The LCR 600 alphanumeric keypad consists of 14 domed keys. The keys collapse and pop up to give a
tactile, positive confirmation of keystrokes. The keypad multitap functionality allow users to input up to
four characters with one key.

Introduction
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.

Meter System Overview
Meter System Components
METER SYSTEM
A Liquid Controls meter system not only accurately measures product, it also regulbates and purifies
product flow 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.

Introduction
VALVES
Valves control the flow 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 flow rate to a dwell
flow on preset deliveries. By slowing the flow 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 M400-11 and
M400-40.

Introduction

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.
XL LED REMOTE DISPLAY
The XL LED Remote Display’s six 2¼” high digits, each consisting of 18 red LED lights, are discernible
from up to 250 feet away. Hard wire data communication with the LectroCount LCR 600 is required. See
manual EM300-55.
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. Multilayered 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.

Introduction
PULSE OUTPUT DEVICE
The Liquid Controls Pulse Output Device (POD pulser) converts the rotary motion of a positive
displacement flowmeter 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 EM300-11.
DIFFERENTIAL PRESSURE (∆P) TRANSDUCER
The differential pressure transducer, common in aviation applications, monitors the differential pressure
(pressure drop) across a full flow 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.
