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 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.
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.
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,
ve 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, 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.

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.
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-II is required. See manual EM300-55.
