NOTE: Throughout this manual, both the LCR.iQ and MASTERLOAD.iQ are
referred to as “Register” (unless otherwise specifically referenced by name).
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.
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.

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.)

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.

Page 10
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).

ESD Precaution
Install the Ground Strap Kit before installing the register.
Grounded Passenger Seats
Some truck seats, typically passenger seats, are not adjustable and do not require grounding.

Ground Strap Kit

All seat cushions are grounded in a similar manner. The illustrations below detail the following instructions for grounding three typical types of truck seats.
Follow these steps to ground a truck seat:
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 floor. 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, flat washer and nut provided.
Get the latest PDF manual: https://www.lcmeter.com/resources/technical/manuals Mobile/online version of this manual: https://www.lcmeter.com/manuals
30
Page 31
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.
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.
·
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 traffic areas in the cab.
6. Check the strap for a good ground connection (see below).

Page 33
Turn off accessories
If the multimeter reads “MΩ” or “KΩ”, typically, one of the
accessories is still on.
Verify good contact
If operator receives a ESD discharge when leaving the seat, the ground strap is not installed correctly.

Check for a Good Ground

After installing the ground kits, use a multimeter to confirm that the seat and printer are both grounded properly.
Follow these steps to verify 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.
·
If the resistance is less than 3Ω, the system is grounded adequately.
·
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.

The Register can be mounted directly onto a flow meter; however, it may also be mounted away from the meter in a more ergonomic or advantageous position, on a control panel or control pedestal. If the meter is equipped with an external POD pulser, the Register can be mounted up to 1000 feet (304 meters) away from the meter (actual distance depends on pulser specifications and wire type).
·
The meter mount design consists of an enclosure base with a round mounting surface that mates perfectly with standard LC register adapter bracket or industry standard register
mount and can be mounted in 45° increments.
·
The panel mount design consists of an enclosure base with mounting tabs to allow the register to be conveniently mounted on a flat panel from the front or rear of the panel for a
very clean and wire-free installation from the operator's point of view.

Routing the Data and Power Cables

Data and Power Cable
The Register shipment typically includes a gray 50-foot power cable and a 50-foot black data cable, pre-wired to terminal blocks on the Register CPU board. On typical truck installations, the cables must be routed from the back of the truck–where the Register is installed–to the front of the truck, where the accessory panel is and the printer is typically installed. The black data cable connects to the printer, typically mounted in the truck cab. The gray power cable hooks up to a power source. During installation, follow these guidelines and ensure the cables remain undamaged.
During installation, follow these guidelines and ensure the cables remain undamaged.
Guidelines for routing the data and power cables on the outside of the truck
·
LC recommends that both cables be run through 1/2" automotive plastic corrugated split loom or through flexible 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, mufflers, etc.

·
Keep cables away from moving suspension components and other moving truck components.
·
If the cables are shortened, ensure that you use the proper tool for stripping off the insulation on the cables.
·
Ensure that all cabling and wiring connections are connected to the proper terminal locations.
Guidelines for routing the data and power cables inside the cab
·
Before you begin, layout positions for the component and pathways for the cable.
·
Ensure that the printer and the wires will not obstruct other vehicle components.
·
Keep cable pathways away from heavy traffic areas and locations where they may be vulnerable to damage.
·
Remember to provide plenty of room around the components, so the cables can be easily connected.
·
Avoid installing the cable where it will be exposed to excessive flexing.
·
Ensure that 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.
·
Ensure cables are not fastened to adjustable seats.

Compatibility
The Register is also compatible with many other brands and types of valves.

Valves

When ordered as part of a meter system with a Register, Liquid Controls control valves are bolted onto the meter and wired to the Register at the factory. Electronic control valves can also be ordered separately and retrofitted onto meter systems already in service. These valves will need to be piped and wired in the field. For piping instructions, refer to the valve manual. This manual includes wiring instructions for the valves.
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 flow. Dwell flow is a low flow rate setting controlled by the S2 solenoid and initiated shortly before the register reaches a preset value.

Power Supply

When you have made all of the data connections and complete installation of all components, connect the power to the Register and the Epson printer. Before making the power connections, go through the vehicle system checklist below, and ensure that the electrical system of the truck meets the minimum requirements for powering the Register and the Epson printer.
Vehicle System Checklist
·
Clean any corrosion from the battery terminals and battery cable to guarantee a solid, tight connection.
·
Charge the battery according to manufacturer specifications.
·
Ensure the alternator is large enough to meet the total demands of the truck, including the Register. The Register requires a minimum of 5 Amps for proper operation. Run the truck at low idle, with all accessories on (including hose reel). Check the voltage with a multimeter to confirm that the voltage doesn't drop below 11 Volts.
·
Inspect the electrical equipment on the vehicle to ensure proper installation and operation.
·
Determine whether the vehicle is grounded positively or negatively. Consult Liquid Controls if the vehicle has a positive ground.
·
Ensure that any radio antennas are installed according to manufacturer specifications to prevent RF interference.
Connect the Power
All Register shipments typically include a 50-foot gray power cable (100-foot and 300-foot cables are also available) and a 5 Amp fuse.

Power Check
After the Register has been installed, check to ensure that it powers up correctly. The Registerdisplay and the printer power light should come on when the truck ignition is turned either to the ON position or the ACC position. Ensure that the printer power switch is on. If the
Register or the printer does not power up, check the wiring and the connections on the Register board against the instructions in this manual.

IMPORTANT: Before Sealing the Register
After correctly powering up the Register, continue on to the Register Setup and Operation manual to setup the Register for operation. We recommend that you setup and test the Register before closing and sealing the unit.

Finalize the Installation

Close and Seal the Unit
After setting up and testing the unit, complete the installation by closing and sealing the housing. The Register must be environmentally sealed to protect the electronics against the elements. The Register must also be sealed by a Weights & Measures representative to guarantee that the register is operating at the proper regulatory standards.
1. Secure the cables behind the Register and the cables in the cab with cable ties.
2. If conduit was used during the installation, fill the conduit end inside the Register with
silicon RTV (provided with shipment, PN 82575). Read and follow the directions of the Environmental Sealing Guidelines, below.
3. Tighten the four socket head cap screws on the four corners of the cover housing using a 3/16 hex key or bit. Ensure that the gap between the cover and the housing is completely closed. Ensure that the calibration screw is tightened to approximately 7-lb– and properly sealed. Read and follow the directions of the Environmental Sealing Guidelines, below.
4. Seal the cover, base, and calibration screw with a wire/lead seal. See the Weights & Measures Seals section below.
Environmental Sealing Guidelines
The Register includes sensitive electronic components, including a microprocessor 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 mitigates the problem of corrosion due to moisture, but this measure only protects the board from small amounts of moisture trapped inside when the

Sealing the Register is the Responsibility of the Installer
There is no product warranty coverage for any water or moisture damage to the Register that results from improper sealing.
lid is closed in humid conditions. It is not adequate for protecting the unit over time if a continuous leak is present in the enclosure.
1. Conduit Entrances
The Register housing has 11 conduit entrances, all are ½" NPT female threads. Use only ½" NPT male threaded fittings on the conduit entrances. Thread sealant must be used with NPT threads. Pressed-in Caplugs or straight (rather than tapered) threads are inadequate for sealing these entrances. Acceptable fittings include metal or plastic conduit, pipe plugs, or cable glands.
Apply PTFE-based “pipe dope” to threads, or wind a minimum of two revolutions of PTFE tape prior to installation. Engage the threads with a minimum of four full turns.When using cable glands, ensure that 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 accommodates for multiple cables. When using conduit or Liquid-Tite, ensure that the opposite end is connected to an environmentally sealed device. If the conduit is not sealed at the other device, fill the interior of the conduit at the Register 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 Register cover properly, ensure that the O-ring surrounding the cover is fit snug inside the groove, and securely tighten the cover screws.
3. Shaft Seals
Units with internal pulsers have an O-ring around under the pulser inside the enclosure, and also a pulse encoder drive shaft that extends through the bottom of the Register housing. If a drive shaft adapter was attached at installation, ensure the O-ring around the shaft is securely

seated in the counter bore of the casting, covered with the flat washer provided, and held in place with the cotter pin provided.
Any water or moisture damage to the Register as result of improper sealing will not be covered under the product warranty. Sealing the Register is the responsibility of the installer.
Weights & Measures Seals
To detect possible intrusions into Weights & Measures approved calibrations on a Register, retainer holes have been drilled into the side of the enclosure adjacent to the Weights & Measures Screw. Properly tighten the Weights and Measures screw to approximated 7 lb-in of torque or the proper visual tightening.
To seal according to Weights & Measures standards, a wire is threaded through the retainer holes and closed with a lead seal.
