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 significant 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-II 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 fixed 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 fixed installations require and additional grounding method to ensure a proper ground.

Alternate grounding method for AC fixed installations

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 protected from ESD by the LectroCount register housing which is grounded to the chassis.

LCR-II Overview

LectroCount LCR-II Overview

General Information

The Liquid Controls LectroCount LCR-II is a microprocessor-based electronic meter register that can be used for Weights & Measures approved custody transfer actions in mobile or fixed installations. The

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

In order to calculate flow measurements from a positive displacement meter, the LCR-II receives a pulse input from an internally mounted quadrature pulser that is mechanically connected to the flow meter (retrofit 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-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 RS485 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

a Weights and Measures sealable fastener opposite the hinges. There are seven machined ports, five ½” NPT ports and two ¾” NPT ports, on the back of the

LectroCount LCR-II to provide secure cable connections for all external devices.

Display

The 1” display is a six character, backlit LCD display.

Navigation Keys

The LCR-II has two domed navigation keys to perform basic configuration and functions. The keys collapse and recover to give a tactile, positive confirmation of keystrokes.

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.

Functionality and Operation

The principle functions of the LectroCount registers include:

Calibration (single and multipoint)

Weights & Measures custody transfer (product delivery and ticket generation)

Metrological data collection

Presetting by volume

Multiple production selection

Security settings

Air and vapor elimination (with proper accessories)

Valve control (with proper accessories)

Electronic temperature volume compensation

(ETVC) (with proper accessories)

Meter System Overview

Meter System Components

Meter System

A Liquid Controls meter system not only accurately measures product, it also regulates and purifies product flow 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-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

Valves control the flow 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 flow rate to a dwell flow on preset deliveries. By slowing the flow 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-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 temperature probe inserted into the strainer housing.

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. Multilayered 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.

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-II is required. See manual EM100-13.

Pulse Output Device

The Liquid Controls Pulse Output Device (POD pulser) converts the rotary motion of a positive displacement flowmeter 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-II register is installed at a distance from the meter. The POD pulser requires hard wired data communication with the LectroCount LCR-II. See manual EM300-11.

Differential Pressure (∆P) Transducer

The differential pressure transducer, common in aviation applications, monitors the differential pressure

(pressure drop) across a full flow 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-II 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-II. 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 flow of data between the LCR-II and back office accounting software. The DMS i1000 must be hard wired to the LectroCount LCR-II. See manuals EM200-10 and EM200-11.

Lap Pad

The lap pad programs and displays all operational functions of the LectroCount LCR registers. It has a large, tactile, alpha-numeric keyboard and a dual line, backlit display. A 3-terminal lap pad adapter is provided with each lap pad. The adapter provides a junction for the lap pad, the printer, and the LCR printer cable.
