1. GENERAL INFORMATION:

1.1 INSTALLATION GUIDE

1.1.1 Introduction:

The installation guidelines are specific to the T675 Totalizer. Please refer to the individual technical data sheets for information pertaining to the turbine flowmeter, RTD temperature probe, and printer. Compliance with the following basic guidelines permits the user to acquire maximum benefit of this asset.

1.1.2 Precautions:

The T675 incorporates sophisticated electronic components and many safeguards have been designed to minimize susceptibility to static discharge and stray voltages. Every precaution for safe handling should still be observed. The most common is to eliminate static or stray voltage by grounding oneself touching a conductive discharge surface. Welding in the proximity of the T675 is not advised. Disconnect ALL cables at the T675 prior to welding activity. The display lens is a plastic composite and should be cleaned with a soft fabric cloth. Paper towel products or dirty leather gloves will score the lens and obscure visibility.

1.1.3 Totalizer:

The T675 should be mounted at a convenient viewing height and angle that minimizes the reduced visibility caused by direct sunlight. Accessibility is also a prime consideration. A thin application of an Oxygen compatible lubricant on the threaded bolts of the securing knobs eliminates any corrosion opportunity. The threaded brass receptacle prevents galling. Although the T675 has been designed to withstand the rigors of the cryogenic transport environment, placement under piping that defrosts or in the proximity of pumps that spray liquid is not recommended.

1.1.4 Interconnecting Cables:

All cables should be secured in place with proper stress relief and avoiding contact with the piping. Sufficient slack should be maintained in the cables to permit the T675 Totalizer to be rotated forward for easy access to the rear panel connections. Additionally, a thin application of a non-conductive Oxygen compatible lubricant to the male threads of the nickel-plated connectors will provide an additional moisture barrier. To minimize interference of other operating systems or low voltage events the power cable should be terminated at the battery or the most direct input source. The power input is polarity insensitive. S.I. strongly recommends that power for the T675 be direct to the source.

2. FEATURES OVERVIEW:

2.1 INTRODUCTION

The Model T675 Delivery System is a thoroughly engineered electronic totalizing system that incorporates the latest technology and provides the most comprehensive features available to the industry. The T675 is designed to accurately compute and display in real time, pertinent flow parameters in both digital and graphic form. The displayed total of the product being delivered is continually corrected for the temperature of the product. Additional accuracy can be acquired by linearizing the turbine flowmeter input signal. The T675 math processor permits direct reading of product totals in any desired engineering unit in both US Customary and SI i.e., gallons, liters, pounds, kilograms, scf, m3 etc.

This next generation system delivers the most sought after system enhancements while maintaining a user-friendly simplicity of operation. The Model T675 configuration settings can be reprogrammed in the field with relative ease. Programming the T675 is simply a matter of selecting the desired operating criteria from an all-inclusive menu thus eliminating the need to scroll through an entire flow chart to enter or change select data. Display of various flow properties such as temperature and flow limits, fluid density, and equivalent volume is achieved automatically with the selection of product to be measured and turbine size.

Fault detection and identification has never been easier. In addition to standard alarm icons the T675 provides a “Detail Display” that lists operating conditions such as supply voltage, internal battery voltage, signal input frequency, coil and RTD resistance, product and fluid temperature to name a few. Additionally, a System Alarm Log catalogs 16 events.

The T675 Maintenance program with ICON reminders can be customized to account for the varying operating conditions that exist between installations. This feature allows the end user to extract maximum real world service intervals without sacrificing effective maintenance.

2.3 SYSTEM OVERVIEW

When introduced to flow the turbine flowmeter generates an AC sinewave signal within the pickup coil located directly above the turbine’s rotor. The signal of the pickup coil is amplified, divided, corrected, and displayed by the T675. The displayed total is corrected for temperature by sensing the resistance of the RTD temperature probe. Delivery information, consisting of 17 selectable parameters, is transmitted via Bluetooth, the Infrared (I.R.), or RS232 communications port depending on which data collection device or printer is selected. This unique integrated system provides the end user a configurable, compact total delivery system.

2.4 THEORY OF OPERATION

The S.I. turbine flowmeter is a volumetric measurement device that measures fluid velocity with one moving component, the rotor. The momentum of the flowing fluid engages the low mass rotor resulting in the rotor rotating at an angular velocity that is proportional to the fluid velocity. The rotor’s rotation generates an AC sinewave signal in the pickup coil. S.I. turbine flowmeters are linear devices therefore the signal output frequency is proportional to the flowrate within the designed flow range. Another benefit of a linear turbine meter is its Kfactor, the number of pulses generated per unit volume (gallons, pounds etc.) is consistent over the entire flow range. The total number of pulses generated is directly related to the total volume. The displayed total in the desired engineering unit is acquired by dividing the total pulses by the Kfactor. Because volumetric flowmeters and product density are influenced by fluid temperature, temperature must be measured and calculated into the final summation for the displayed total to be exact. A temperature compensation algorithm accomplishes this by computing the fluid density for the measured temperature and adjusts the volumetric or mass delivery total.

Simply stated, temperature compensation adds pulses to the pulse total when the detected temperature is colder than the products reference temperature and subtracts pulses when the product temperature is warmer than the reference temperature. The rate at which the pulses are added or subtracted is determined by the measured temperature departure from the products reference temperature.

2.5 CONTROL PANEL INDICATORS

POWER INDICATOR: A Green LED illuminates when the T675 is “On” and is extinguished when the T675 is “Off”. SIGNAL INDICA TOR: An Amber LED flashes when an input signal is present. SYSTEM ALARM INDICATOR: A Red LED flashes indicating the presence of an Alarm or Maintenance condition. BLUETOOTH INDICATOR: A purple LED flashes when searching for a connection and is on steady when connected.

2.6 CONTROL PANEL PUSHBUTTONS

ON/OFF PUSHBUTTON: Momentarily depressing the On/Off pushbutton will turn the T675 system “On” illuminating the

green LED. The system resumes operation exactly as existed at the moment of the last power “Off”. In order to turn the T675 “Off” during normal operation you must depress and hold turn “Off”. During the brief delay the Green Power LED will flash as a warning indicator. Once the display backlight extinguishes the On/Off pushbutton can be released. As a safeguard, during some critical operations such as system setup, the On/Off pushbutton is disabled. This allows the operator to complete the setup operation (or exit setup first via the Reset/Esc key). Either way changes will be saved before the system powers “Off”.

KEYPAD: A 16 pushbutton keypad, 10 numeric, decimal point, backspace key () and 4 special function keys, used for data entry during setup of the T675. During normal operation (Operating mode) the keypad is disabled with the exception of the Setup key.

SETUP: Changes the T675 from the Operating to the Prove mode. RESET (ESC): Enables escape function, will initiate system reset only in Programming mode when “double

the key. During normal operation the Detail, Reset, Print, and Alarm softkeys are depicted on Display.

DETAIL SOFTKEY: Depressing this softkey will display the Detail Display. Once the Detail Display is displayed the softkey now converts to a Hold softkey and retains the Detail Display until this softkey is released. Releasing the Hold softkey permits the display to return to the Operating Display. Two additional softkeys are displayed while in the Detail Display, Bat Test, and Ok softkey.

RESET SOFTKEY: Depressing this softkey resets the Delivery Totalizer. This softkey is disabled during delivery unless the unit is in the Prove Mode.

PRINT SOFTKEY: Depressing this softkey downloads delivery data selected in T675 Settings Menu page 2 Items 2,3 for a period of time as programmed in T675 Settings Menu page 2 Item 5 . This key will not be displayed if the printer output has been disabled in the T675 Settings Menu page 1 Item 6.

ALARM SOFTKEY: Depressing this softkey displays a description of all current alarm conditions. Once the Alarm Display is displayed this softkey converts to an Ok softkey. A Hold and Next softkey also appear. Hold retains the display until released plus 5 seconds, Ok returns to the Operating screen immediately, otherwise the Alarm Display is retained for 5 seconds. Depressing Next will display all delivery

alarms that occurred.

2.7 DISPLAY

The T675 has 4 primary Displays; Power Up, Operating, Detail, and Prove. In addition there are 3 primary menu Displays, the Initialization Menu, Adjustment Menu and the Settings Menu.

2.7.1 Power Up Display

When the T675 measurement system is initially turned “On”, this displays the self-test results, software version identification and temperature correction curves. Additionally, a configurable message can be programmed and displayed on the lower portion of the Display. The message is factory configurable and must fit within an area of 48 x 240 pixels. For more detailed information about “power on self-test” consult the SYSTEM DIAGNOSTICS section of this manual.

2.7.2 Operating Display

CUSTOMER'S ICON: The icon is located in the upper left corner of the display and can be customized for the end user.

The icon must be digitized to fit within 24 x 24 pixels. TIME & DATE: The current time and date as set by the system's real time clock (24-hr format). The colon separating the

hours and minutes will flash once per second to indicate that the system is functioning. Note that the clock is automatically corrected for the transition between Daylight savings time and Standard time.

TEMPERATURE BARGRAPH: The temperature bargraph indicates the process temperature of the product being delivered in relation to the minimum and maximum temperature limits automatically determined by the product correction table loaded into the system when the product is selected. The product and digital temperature are displayed directly beneath the bargraph. Temperature unit as selected in the Setup menu is displayed above the bargraph. The temperature bargraph is updated every second. Note: if the delivery temperature is out of range, the 'Temp' descriptor above the bargraph and red System Alarm LED will flash.

FLOWRATE BARGRAPH: The flowrate bargraph indicates the current flowrate of the product being delivered in relation to the minimum and maximum flowrate limits automatically determined when the turbine flowmeter size is selected in the Setup menu. The flowrate is digitally displayed directly beneath the bargraph in engineering units selected in the Setup menu. The engineering unit of the rate is displayed above the rate bargraph. The flowrate is calculated with the Kfactor entered in the Setup menu. The flowrate bargraph is updated every second. Note: if the delivery flowrate is out of range, the 'Rate' descriptor and red System Alarm LED will flash (only when the “Use dual coil” option is set to “Off”).

ACCUMULATIVE TOTALIZER: The 'small' 9 digit totalizer. This totalizer is “slaved” to the Delivery Totalizer and

increments in the same engineering units. The total is “Privilege” passcode protected and can only be Reset by factory personnel. If the engineering unit of the total is changed, the displayed accumulated total will be converted automatically to the equivalent total in the new engineering unit.

KFACTOR INFORMATION: The displayed Kfactor information has a dual purpose. If the linearizer is inactive, the displayed Kfactor represents the latest Kfactor entered into the setup menu. If the linearizer is active, the Kfactor information is replaced with the word linearizer. The instantaneous calculated linearized Kfactor based on flow rate is available on the Detail Display.

DELIVERY TOTAL: The 6-digit delivery total represents the cumulated total since the last Reset action. (Refer to RESET softkey pg. 4) The delivery total is the total pulses generated divided by the Kfactor and corrected for temperature if compensation is activated. If the engineering unit of measure is changed the displayed delivery total will be automatically reset to zero.

Directly above the Delivery Totalizer the engineering units of measure and delivery conditions are displayed. If the temperature compensator is activated and the delivery temperature is within range, the engineering unit of measure will be displayed with 'corrected @ NBP'. The total will be corrected to metered conditions, (at the measured temperature). If the delivery temperature is out of range, '@ DEFAULT TEMP' will be displayed and the delivery total will be corrected at the warmest delivery temperature for that product. Depressing the  key will change the displayed total to the uncorrected quantity and '–uncompensated' will be displayed above the total. If the temperature compensator function is turned “Off”, '@ NO TCF' will be displayed and the TCF will be 1.000, (volumetric).

The delivery totalizer will continue counting in the event of a temperature failure if “Count while temp fail” option is selected in the Setup menu. If “Totalize during alarm” is selected the totalizer will operate at the warmest temperature value (default temp) for the selected product while the temperature is out of range.

PUMP ICON: The pump icon indicates the status of the delivery pump. When the pump icon is not displayed, the delivery pump is enabled. A temperature and time based pump cooldown feature can be activated by enabling the Pump Cooldown Timer. In the event of an intermittent non-fatal temperature error, the Intermittent Temp Tolerance Timer is activated. This programmable timer specifies a time period during which a temperature fault is allowed to exist without disabling the delivery pump. During this failure a thermometer icon with an upward pointing arrow and countdown timer will appear on the Operating Display indicating the number of seconds remaining before the temperature fault will disable the delivery pump unless corrected. Failure to correct the temperature fault within the specified time will cause the pump icon to be displayed, disable the delivery pump, and reset the Pump Cooldown Delay Timer to the programmed value. When the fault is corrected and the temperature returns within range, the pump cooldown delay timer will decrement toward zero. If no further temperature errors occur, the pump cooldown delay timer will reach zero, the pump icon will disappear, and the delivery pump will be enabled.

SYSTEM MAINTENANCE ICON: An oil can icon indicates that a system maintenance alarm condition exists. An abbreviated alarm message is displayed below the icon identifying the component. If more than one alarm condition exists, the alarm message(s) will be displayed in a sequential fashion. Depressing the ALARM softkey will display all current alarm conditions. The System Alarm Log in the “675 settings menu” maintains an alarm event history that can be accessed by Privileged or User passcodes. The System Alarm LED indicator flashes during any alarm condition. In the event a low power condition is detected, the alarm icon converts to a gas pump and begins a 2 second countdown. During this low power condition, the system turns off the LCD backlight to conserve power and begins operating off the internal lithium battery. If the incoming power is restored within 2 seconds, the system will refresh and operate normally. If, however, sufficient power is not restored, the system will save all operating parameters and shut itself “Off”.

*T675* MESSAGE: This message indicates that the unit is in the normal Operating mode. When this message is replaced with ‘PROVER’ the unit is operating in the Prove mode.

2.7.3 Detail Display

The Detail Display shows hardware information and additional current operating conditions of the system. A total of 14 parameters are available for review; Adjustment Mode access status, dual coil status, Input voltage, Battery voltage, P/U coil ohms, LCD Heater status, Input frequency, Kfactor, RTD ohms, Communications Baud rate, Printer Status, T/C factor, Density, Delivery product and Temperature. The temperature is displayed in digital and bargraph format.

3 Softkeys displayed with the Detail Display:

BAT TEST SOFTKEY: Depressing this key while in the Detail Display instructs the system to test the T675

backup battery. This test involves applying a 35mA load to the battery for 2 seconds, reading and storing the battery voltage. Since this test evaluates the battery’s condition by applying a load, it is recommended that this test be conducted only if either Batt is below the Maintenance icon or a new battery is installed. The system automatically performs this test at the beginning of each month.

OK SOFTKEY: Depressing this key terminates the Detail Display and immediately returns the display to the Operating Display.

HOLD SOFTKEY: Depressing this key retains the Display, when released the system will automatically revert to the Operating Display after several seconds.

2.7.4 Prover Display

Depressing the Setup key located on the keypad accesses the Prover Display. This Display is identical to the Operational Display with the exception of the *T675* icon is replaced with the word PROVER. The function of the Prove

mode is examined in detail below. Note: When the Program Enable Module (PEM) is secured to the T675, the Setup key is disabled and access to the Prove mode is denied.

2.8 MODES OF OPERATION

The T675 program offers 3 modes, Operating, Programming, and Prove. Any mode that can affect the calibration of the T675 is passcode protected. The T675 has a 2 tiered passcode level of security, Privileged and Weights and Measures. The Privileged passcode is maintained exclusively for Factory use and allows access to ALL menu options. The Weights and Measures passcode allows access to all displayed menu options except Initialization Options 5,8, and 9.

2.8.1 Operating Mode

The Operating mode is the power up mode for the T675, all others must be accessed with a passcode. The Operating Display containing all delivery vitals is the normal display for this mode. The Detail Display is also accessible in this mode without a passcode.

2.8.2 Programming Mode

The Programming mode and associated menu’s allow the T675 to be configured to the operating conditions of the application. When accessed, the first Display is 675 Initialization Options menu containing 8 options. Options 2, 3, 5 and 8 are passcode protected. Options 5, 8, and 9 require a Privileged passcode and are intended for Factory use only. The Programming mode is quite extensive and is explained completely beginning with the 675 Initialization Opti o n s Menu on page 7.

2.8.3 Prove Mode

The Prove mode permits convenient calibration of the trailer’s delivery system. This mode temporarily aborts certain safeguard features and therefore is passcode protected. To access this mode, depress the SETUP key while in Operating mode. The system will prompt for a passcode, either user or privileged, to be entered. If an incorrect passcode is entered or the RESET/(ESC) key is depressed, the T675 will revert to the Operating mode. The Prove mode allows entering, changing or viewing the Kfactor. The Prove mode is retained until the T675 is either turned “Off” or no flow activity for 5 minutes. The Prove mode has the following operational characteristics:

• The *T675* message is replaced with the PROVER message

• The SETTINGS passcode is not required to change the Kfactor

• The pump cooldown timer is disabled (pump enabled)

• The I.R. communications port is disabled

• The Totalizer can be reset regardless of flowrate

• “Not a legal delivery” is displayed above the delivery totalizer and on a printed ticket
