LCR.iQ/MasterLoad.iQ
Product Manual
Congratulations on ownership of the new LCR.iQ or MasterLoad.iQ electronic meter register
and controller. This manual provides the technical details on installation, hardware, setup,
operation, and regulatory information for your register.
NOTE: Throughout this manual, both the LCR.iQ and MASTERLOAD.iQ are
referred to as “Register” (unless otherwise specifically referenced by name).
The Register calculates, monitors and records volumetric data from bulk flow meters, provides
fluid transfer process customization and automation, ties in critical system sensors and inputs,
and bridges data communication between the operator, the equipment, and the operator’s
back office if necessary.
The Register is specially designed to work with leading bulk fuel meters such as LC and
Avery-Hardoll, but will easily retrofit into existing systems with other flow meter brands.
The Register provides many new features, yet supports backward compatibility with LCR-II
and LCR-600.

Register Overview
The Register is a microprocessor-based electronic meter register that can be used for
Weights & Measures approved custody transfer actions in mobile or fixed installations. The
Register is a self-contained unit. All operation, setup, and configuration functions can be
carried out using the Register function keys and alphanumeric keypad. No lap pads, laptops,
or other data entry devices are required.
A complete Liquid Controls meter system not only accurately measures product, it also
regulates product flow and removes contaminants in order to produce the optimal conditions
for measurement. Typical systems include an air/vapor eliminator, strainer, meter, register,
and control valve.
Basic Functions
The principle functions of the Register registers include:
· Weights & Measures custody transfer (product delivery and ticket generation)
· Metrological data collection
· Preset deliveries by volume
· Multiple product selection
· Multi-point meter calibration
· Security settings
· Air and vapor elimination (with proper accessories)
· Single and dual stage valve control (with proper accessories)
· Electronic Temperature Volume Compensation (ETVC)

injury, or death from fire and/or explosion, property damage, or other hazards
that may be associated with this type of equipment.
SAFELY EVACUATE PIPING SYSTEM
Before disassembly of any meter or accessory component: ALL INTERNAL
PRESSURES MUST BE RELIEVED AND ALL LIQUID DRAINED FROM THE
SYSTEM IN ACCORDANCE WITH ALL APPLICABLE PROCEDURES.
· Pressure must be 0 (zero) psi.
· Close all liquid and vapor lines between the meter and liquid source.

OBSERVE NATIONAL & LOCAL CODES
Power, input, and output (I/O) wiring must be in accordance with the area
classification for which it is used (Class I, Div 2). For North America, installations
must be per the U. S. National Electrical Code, NFPA 70, or the Canadian
Electrical Code in order to maintain Class I, Division 2 ratings. This may require
using connections or other adaptations in accordance with the requirements of
the authority having jurisdiction.
Peripheral equipment must be suitable for the hazardous location where it is
installed. (L'équipement périphérique doit être adapté à la zone dangereux où il
est installé.)
WARNING: Explosion Hazard
When in hazardous locations, turn power OFF before replacing or wiring
modules. (Lorsque dans des endroits dangereux, coupler le courant avant de
remplacer ou de câbler des modules.)
DO NOT disconnect equipment unless power has been switched OFF or the area
is known to be Non-Hazardous. (NE PAS déconnecter l'équipement san coupler
l'alimentation ou sans s'assurer que la zone est non dangereuse.)
WARNING: Use 3.5 in • lb (0.4 N • m) torque when tightening terminal block
screws.

ESD Protection
ESD Precaution
Opening the Registers
Follow this procedure each time you open the Register or approach it with the door open:
Before opening the Register and handling the CPU board, it's 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 Register housing, the meter, truck piping, or the bumper.
When the maintenance is complete and the Register door is closed, the CPU board is
protected from ESD by the Register housing which is grounded to the chassis.
Preventing ESD Damage
To prevent electrostatic discharge (ESD) damage to the Register, truck installations must
properly ground the truck seat cushion and the Epson printer chassis. Prolonged exposure to
ESD over weeks, months, or years can corrupt register memory and damage the electronic
components in Register registers (as well as other electrical components in the truck 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 proper bonding, static electric charge builds between the seat cushion and the
operator. This electric charge can enter the Register from any point in the truck electrical
system, including register power and printer cabling.
Liquid Controls Grounding Kits
All truck installations of the Register must have grounded seats and printers using the following
kits:
· Ground Strap Kit (LC Part Number 82185)
· Epson Printer Ground Wire Kit (LC Part Number 82184)
Properly grounded seats allow static electricity to ‘bleed off’ before it can build up, discharge,
and damage the Register or other electrical components.

The Epson Printer Ground Wire Kit is included with each Epson printer cable kit shipment. For
existing installations and previously purchased registers / printers, both ground kits are
available from LC.
Grounding with a Meter Mount or Remote Mount
In an installation where the Register is mounted directly to the meter, the Register housing is
grounded through the meter. If the register is not mounted on the meter, you must ensure the
Register housing is grounded properly.
Alternate grounding methods for remote mounted registers
For installations where grounding the register housing through a mount is not possible, an
external grounding screw hole is available. This hole requires a #8-32 x 1/4” ground screw–
which is supplied with the register (the LC part number for the screw is 08254)–and also a 12
gauge or larger stranded wire connected to a known ground (less than 1 ohm).
Another option is to connect the ground screw 8-32 x 1/4” ground screw (inside the Register
housing) to a 12 gauge or larger stranded wire connected to a known ground (less than 1
ohm).
