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
• Multiple production selection

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.

LECTROCOUNT GROUND STRAP KIT
LectroCount Ground Strap Kit
All seat cushions are grounded in a similar manner.
The illustrations on the next page detail the following
instructions for grounding three typical types of truck
seats.
To ground a truck seat:
. ESD Precaution .
Install the LectroCount Ground Strap Kit
before installing the LectroCount register.
1. Identify any adjustable, shock absorbing seat in the truck
cab. These seats will typically have pivot points, hinges,
or other mechanical design features that make seat
adjustments possible.
2. Find an existing screw or hole near the back of the seat
frame, close to the cab oor. If a hole or screw does not
already exist, drill a 9/32” hole in the seat frame.
3. Attach one end of the ground strap to the seat frame
bracket using the lock washer, at washer and nut
provided.
4. Find an existing screw or hole, or drill a 9/32” hole,
in the part of the seat frame—above all pivots and
adjustments—that is attached directly to the seat cushion.
Make sure that there are no intervening pivot points,
guides, adjustment mechanisms, etc., which could
interfere with the ground path between the seat cushion
and the ground strap.
4a. If the seat cushion has a wooden base, use a wood
screw and washer to attach the strap lug to the bottom
of the seat at a point where the seat fabric is attached to
the wood. There must be good contact between the seat
fabric and ground strap lug.
5. Use the wire ties provided with the kit and tie off the strap
so that it doesn’t interfere with the movement of the seat
and is clear of trafc areas in the cab.
Grounded Passenger Seats
Some truck seats, typically passenger seats, are
not adjustable and do not require grounding.
Ensure a Good Ground
Remove any dirt or oxidation from the ground strap
contact point. Lock washers should penetrate any
paint to ensure a good electrical connection.

Checking for a Good Ground
After installing the ground kits, use a multimeter to conrm that the seat and printer are both grounded properly.
To check for a good ground connection:
1. Turn OFF all accessories, including the dome light, to prevent other currents from distorting the reading.
2. Take a multimeter and measure the resistance between the brackets the two ground strap bolts are fastened to. Find a clean
spot on the brackets without paint to use as contact points. Other bolts on the brackets are often suitable.
2a. If the resistance is less than 3Ω, the system is grounded adequately.
2b. If the resistance is still greater than 3Ω, check for proper metal to metal
contact on both ends of the ground strap. Clean any paint, dirt, or oxidation
that may block the grounding point. If the resistance remains above 3Ω,
attach the ground strap to a different ground point. Repeat the process until
the ground resistance is below 3Ω.
If the multimeter reads “MΩ” or “KΩ”, typically,
Turn Off Accessories
one of the accessories is still on.

LECTROCOUNT LCR 600 MOUNTING
Mounting Overview
Typically, the LectroCount LCR 600 is mounted directly
onto a ow meter; however, some xed installations
require the register be mounted away from the meter.
If the meter is equipped with an external POD pulser,
the LCR 600 can be mounted up to 1000 wire feet (304
meters) away from the meter (actual distance depends
on pulser specications and wire type).
Adapters are available for other PD meters such as
Neptune (PNs 81364, 82641, 82642), FMC Smith (PN
81370), and Brooks/Brodie (PN 81800) meters. Each kit
includes installation instructions.
Tips for mounting an LCR 600
• Leave the cover assembly fastened to the base to protect
the internal components.
• Make sure the vertical drive shaft from the meter is
attached to the pulser drive shafts.
• Before securing the LCR 600 to the meter or mounting
bracket, make sure the counter is visible and the keypad
and selector switch can be easily operated.

Relieving Internal Pressure
All internal pressure must be relieved to zero pressure before disassembly or inspection of the strainer, vapor eliminator, any
valves in the system, the packing gland, and the front or rear covers.
Serious injury or death from fire or explosion could result in performing maintenance on an
improperly depressurized and evacuated system.
Relieving Internal Pressure Procedure for LPG and NH3 Meters
1. Close the belly valve of the supply tank.
2. Close the valve on the vapor return line.
3. Close the manual valve in the supply line on the inlet
side of the meter. If no manual valve exists on the inlet
side, consult the truck manufacturer for procedures to
depressurize the system.
4. Slowly open the valve/nozzle at the end of the supply
line.
5. After product has bled off, close the valve/nozzle at the
end of the supply line.
6. Slowly crack the tting on top of the differential valve to
relieve product pressure in the system. Product will drain
from the meter system.
7. As product is bleeding from the differential valve, slowly
reopen and close the valve/nozzle on the discharge line.
Repeat this step until the product stops draining from the
differential valve and discharge line valve/nozzle.
8. Leave the discharge line valve/nozzle open while working
on the system.

• LC recommends that both cables be run through ¾”
automotive plastic corrugated split loom or through
exible liquid-tight conduit for protection.
• Make sure the loom or conduit runs down the inside edge
of the trucks frame rail and fasten every 2’ with cable ties.
• Install rubber grommets to protect the cables where they
pass through the cab wall, meter box, etc.
• Keep the cables away from heat sources such as the
engine exhaust, manifold, exhaust pipe, mufers, etc.
• If the cable glands are removed from the register, apply
pipe sealant or PTFE tape on the gland threads before
re-installing.
• Keep cables away from moving suspension components
and other moving truck components.
• If the cables are shortened, make sure you use the
proper tool for stripping off the insulation on the cables.
• Make sure cables are connected to the proper terminal.
Routing LCR 600 Data and Power Cables
Guidelines for routing the data and power cables
inside the cab
• Layout positions for the component and pathways for the
cables before beginning.
• Make sure the printer and the wires will not obstruct other
vehicle components.
• Keep cable pathways away from heavy trafc areas and
locations where they may be vulnerable to damage.
• Remember to save room around the components so
cables can be easily connected.
• Avoid installing the cable where it will be exposed to
excessive exing.
• Make sure cables are not pulled too tight in areas that will
move. For example, when wiring cab-over trucks, leave
enough slack so the cab can be tilted without damaging
the cable.
• Make sure cables are not fastened to adjustable seats.

VALVES
Liquid Controls’ Valves Overview
When ordered as part of a meter system with a LCR
600, Liquid Control’s control valves are bolted onto the
meter and wired to the LCR 600 at the factory. Electronic
control valves can also be ordered separately and retrot
onto meter systems already in service. These valves
will need to be piped and wired in the eld. For piping
instructions, refer to the valve manual. This manual
includes wiring instructions for the valves.

and 3 Way Solenoid
(PN 81527)
Single Stage (S1) Block Valve
Single Stage
3-Way Valve
In order to control ow, the LCR 600 energizes and
de-energizes solenoid-operated valves on external
bypass piping routed off the main product ow. The
solenoid operated valves close off and open the bypass
pipes. The bypass pipes redirect some of the product
ow in order to open and close the control valve. These
solenoid-operated valves must be wired to the LCR 600
CPU board during installation.
Liquid Controls offers single stage and two stage
electronic valves. Single stage valves have one solenoid
valve (S1) and two positions—an open position and a
closed position. Two stage valves have two solenoid
valves (S1 & S2) and three positions—open, closed, and
dwell ow. Dwell ow is a low ow rate setting controlled
by the S2 solenoid and initiated shortly before the
register reaches a preset value.
The LCR 600 is also compatible with many other
brands and types of valves.
SINGLE STAGE VALVES
The three most common Liquid Controls meter systems
with single stage valves include a block valve with a
S1 solenoid-operated valve tted onto external piping
(A2847-11), a block valve (A2843) with a 3-way solenoid,
and an electro-pnuematic valve with an S1 solenoid.

This single stage control valve has a S1 solenoidoperated valve located at the meeting point of three
pipes: one pipe from the inlet side of the valve, one from
the top of the block valve, and one from the outlet side
of the valve. This valve is typically used in rened fuels
applications.
A2843 Valve and 3-Way Solenoid
The 3-way solenoid-operated valve—mounted directly
to the top center port on the back of the LectroCount
LCR 600—serves as a S1 solenoid-operated valve. The
3-way solenoid-operated valve is located at the meeting
point of two pipes from the vapor eliminator (one for
eliminated vapor and one leading to the spit tank) and
one pipe to the top of the block valve. 3-way solenoidoperated valves are typically specied for products that
hold vapor in the line such as LPG and NH3.

VALVES
Single Stage Valves (cont.)
A2700 Series Electro-Pnuematic Valve
Electro-pnuematic valves use a S1 solenoid-operated
valve mounted to a pneumatic actuator to open and
close a V-7 valve. These valves are typically used in high
viscosity applications like lube oil.
TWO STAGE VALVES
The three most common Liquid Controls meter systems
with two stage valves are: a block valve with a S1 and
a S2 solenoid-operated valve tted onto external piping
(A2848-11), a block valve with a S2 solenoid-operated
valve (A2859-11) and a 3-way solenoid on the LCR 600,
and an E-7 valve with a S1 and a S2 solenoid-operated
valve.
A2848-11 Valve
This two stage control valve has a S1 and a S2 solenoidoperated valve. The S1 solenoid-operated valve is
located at the meeting point of three bypass pipes: one
pipe from the inlet side of the valve, one from the top
of the block valve, and one from the outlet side of the
valve. The S2 solenoid valve is located on a bypass pipe
that connects the inlet and outlet sides of the control
valve. It opens while the control valve is closed to supply
the dwell ow. This valve is typically used in rened fuels
applications.

Connect the Power
All LCR 600 shipments typically include a 40' gray power cable (100', and 300' are also available) and a 7.5A fuse.
Page 17 describes the best practices for routing the gray power cable to the truck cab’s accessory panel.
40’ GRAY POWER CABLE
The gray power cable (PN 84046) is prewired to the J8 and J9 terminals on the display CPU board and the J6
terminal on the CPU board at the factory. It includes two 16AWG wires and a ground drain wire. The 7.5A fuse should
be spliced into the red 16AWG wire as close to the power source as possible.
EPSON PRINTER POWER
Power must be supplied to the Epson printer as well. A 15' cable with a 12/24VDC converter (825001) for printer
power supply is also available. The red wire of this cable must be spliced into the red wire of the gray power cable on
the LCR 600 side of the 7.5A fuse.
To connect power to the LCR 600 and the Epson printer:
1. Route the gray power cable to the accessory panel. See
page 17
2. Splice the red wire from the printer power cable into the
red wire of the gray power cable.
3. Splice the 7.5A fuse into the red wire. Make the splice
close to the direct power terminal connection in the
accessory panel and on the power side of the splice
made with the printer power cable.
4. Connect the red wire to the direct power supply terminal
in the accessory panel.
5. Connect the black wire of the gray power cable to a
reliable DC ground.
6. Connect the black wire of the printer power to a reliable
DC ground.
7. Tape the green drain wire of the gray power cable back
against the power cable.
Power Check
After the LCR 600 has been installed, check to make sure that it powers up correctly. The LCR 600 display and the
printer power light should come on when the truck’s ignition is turned to the ON or to the ACC position. Make sure the
printer power switch is on. If the LCR 600 or the printer does not power up, check the wiring and the connections on
the LCR 600 CPU board against the manual.

POST INSTALLATION
IMPORTANT: Before Sealing the LCR 600
After the LCR 600 is powered correctly, continue on to the LectroCount LCR 600 Setup and Operation manual to setup the LCR
Close and Seal the Unit
Once the unit has been setup and tested, nish the installation by closing and sealing the housing. The LCR 600 must
be environmentally sealed to protect the electronics against the elements. The LCR 600 must also be sealed by a
Weights & Measures representative to guarantee the register is operating at the proper regulatory standards.
1. Secure the cables behind the LCR 600 and the cables in the cab with cable ties.
2. If conduit was used during the installation, ll the conduit end inside the LCR 600 with silicon RTV (provided with shipment, PN
82575). Read and follow the directions of the Environmental Sealing Guidelines below.
3. Tighten the cover bolt using a large at-tip screwdriver or a 7/16” socket. Completely close the gap between the cover and the
housing tab. Read and follow the directions of the Environmental Sealing Guidelines below.
4. Seal the cover bolt and the switch plate bolts with a wire/lead seal. See Weights & Measures Seals on pg. 33.
Environmental Sealing Guidelines
The LCR 600 includes sensitive electronic components, including a micro-controller that can be damaged by the
presence of moisture. Therefore, it is essential that all conduit ports, the cover, and the shaft seals be adequately
sealed by the installer to ensure watertight integrity. The conformal coating on the board and a moisture-absorbing
desiccant inside the enclosure mitigates the problem of corrosion due to moisture, but these measures only protect
the board from small amounts of moisture trapped inside the enclosure when the lid is closed in humid conditions.
They are not capable of protecting the unit over time if a continuous leak is present in the enclosure.
600 for operation. You will want to setup and test the LCR 600 before closing and sealing the unit.
Sealing the LCR 600 is the Responsibility of the Installer
Any water or moisture damage to the LCR 600 as result of improper sealing will not be covered under the product warranty.
1. Conduit Entrances
The LCR 600 housing has seven conduit entrances, ve ½" NPT female threads and two ¾" NPT. Use only ½" or ¾" NPT male
threaded ttings on the conduit entrances. Pressed in Caplugs and straight (rather than tapered) threads are inadequate as
seals for these entrances. Acceptable ttings are either metal or plastic conduit, pipe plugs, or cable glands. Threads should
be treated with PTFE-based “pipe dope” or a minimum of two revolutions of PTFE tape prior to installation. Threads should be
engaged a minimum of four full turns. When using cable glands, be sure the gland is sized properly for the outside diameter
of the cable and the elastometric seal around the cable sheath is compressed onto the cable. Use only one cable per cable
gland unless the gland is designed for multiple cables. When using conduit or Liquid-Tite, make sure that the opposite end is
connected to an environmentally sealed device. If the conduit is not sealed at the other device, ll the interior of the conduit at
the LCR 600 with a silicone rubber sealant, such as RTV, to prevent moisture from running down the conduit into the enclosure.
2. Cover Seals
To seal the LCR 600 cover properly, ensure that the O-ring surrounding the cover is t snug inside the groove, and tighten the
cover screw securely.
3. Shaft Seals
Units with internal pulsers have an O-ring around the pulse encoder drive shaft that extends through the bottom of the LCR
housing. If a drive shaft adapter was attached at installation, make sure the O-ring around the shaft is securely seated in the
counter bore of the casting, covered with the at washer provided, and held in place with the cotter pin provided. The control
switch on the front of the LCR 600 is also sealed with an O-ring and held in place by a bushing secured with three socket head
cap screws. When replacing a control switch in the eld, make sure the O-ring is in place on the switch shaft before reinstalling
the switch bushing.

Weights & Measures Seals
To detect possible intrusions into Weights & Measures approved calibrations on a LectroCount LCR 600, llister holes
have been drilled into the switchplate screw and the latch. To seal according to Weights & Measures standards, a wire
is threaded through the llister holes and closed with a lead seal.
