Sponsler, Inc. Model T675 Flow Totalizer Features Overview Pg. 6
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 Options 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
