Sponsler, Inc. Model T675 Flow Totalizer Features Overview Pg. 5
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.
