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-II Overview
GENERAL INFORMATION
The Liquid Controls LectroCount LCR-II is a
microprocessor-based electronic meter register that
LCR-II can control a meter system as a stand-alone
unit, or it can be used as a slave to a host contoller such
as a process controller or an in-cab data management
system.
INPUTS
displacement meter, the LCR-II receives a pulse input
from an internally mounted quadrature pulser that is
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-II 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-II is equipped with a scaled pulse output, two
auxiliary outputs, and two solenoids outputs. These
outputs allow the LCR-II 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-II is capable of interfacing in RS-232 and RS-
485 communication protocols.
HOUSING
The LectroCount LCR-II housing and base are aluminum
die cast and powder coated. The hinge door design
provides easy access to the internal connections and
LectroCount LCR-II to provide secure cable connections
for all external devices.

METER SYSTEM
A Liquid Controls meter system not only accurately
measurement. Optimal systems typically include an air/
vapor eliminator, strainer, meter, register, and control
valve. The LectroCount LCR-II, a register, serves as the
central controller of the meter system. Most components
in the meter system are hard wired to the LCR-II 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-II (in LPG
applications, they are often plumbed to a 3-way solenoid
which is wired to the LectroCount LCR-II). 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-II by separate data
cables. See manuals M300-20 and M300-21.
VALVES
open the line to initiate custody transfers and close the
line to stop custody transfers. Some valves can partially
shut off and provide accurate preset deliveries. Many
valves use solenoid-operated valves that require a hard
wired data connection to the LectroCount LCR-II. See
manuals M400-11 and M400-40.
ELECTRONIC TEMPERATURE VOLUME
COMPENSATION (ETVC) KIT
In order to perform temperature compensation
equations, the LectroCount LCR-II relies on a

PULSE OUTPUT DEVICE
The Liquid Controls Pulse Output Device (POD pulser)
converts the rotary motion of a positive displacement

applications that require explosion proof components in
which the LectroCount LCR-II register is installed at a
distance from the meter. The POD pulser requires hard
wired data communication with the LectroCount LCR-II.

software. The DMS i1000 must be hard wired to the
