Sponsler, Inc. Model T575N Temperature Compensated Totalizer/Printer
PRINTING/RESET
In printing operation, a ticket is inserted into the slot of the ticket tray until it bottoms on the internal stop.
1. Turn the print knob one complete clockwise revolution until a positive stop is reached. As the ticket tray
moves into position, the seal pin pierces the ticket, holding it in place. This initial printing is made with print
wheels at zero. During this initial printing, a shutter moves into place covering the meter register display wheels
and the individual wheels are set to a zero position. At completion of initial print/reset, the display wheels will read
all zeros, the shutter will rise to the normal operating position, and the ticket will be imprinted with all zeros and
locked in place.
2. At the completion of the delivery, turn the knob in a clockwise direction one complete turn until the
positive stop is reached. During this cycle, the ticket tray returns to its original position and the seal pin releases
the ticket.
NOTE: The meter register does not reset to zero at this time.

SWITCH, ADJUSTMENT, INDICATOR DESCRIPTIONS
S1-POWER SWITCH: 3 amp SPST Toggle; Switches fused input power to the logic circuits of the factoring/
compensation module.
D1-POWER INDICATOR: L.E.D. Illuminates indicating power is applied to circuitry.
D2-TEMPERATURE COMPENSATION INDICATOR: L.E.D.
‘OFF’ indicates COMPENSATION
‘FLASHING’ indicates NO COMPENSATION
INTERNAL BOX AND MODULE: Refer to DRAWINGS pg. 8 & 9
F1: INPUT POWER FUSE: 5 amp 3AG
R15: SENSITIVITY ADJUSTMENT: Single turn potentiometer; establishes input signal amplitude required to
initiate the count sequence. Nominal position is with the arrow indicator in the 11:00 o’clock position.
SW1-SW4: FACTORING SWITCHES: 10 position (0-9) BCD; digitally inserts the desired calibration factor with
SW1 as the MSD and SW4 the LSD.
SW5: PRODUCT SELECTOR SWITCH: 10 position (0-9) BCD; selects the product temperature compensation
curve. (See ‘Model T575N option “IC EPROM TABLE, Pg.)
SW6: DIVIDER SWITCH: 10 position (0-9) BCD; digitally sets a divisor (1-10000) to allow entering a calibration
factor with maximum accuracy. (See CALIBRATION)
TP1: GEARPLATE JUMPER: 3 position jumper terminal; Jumper installed for the gearplate used so that the unit
internally adjust the required motor steps.
A (TP5): 2-position jumper terminal; INSTALLED unit will not totalize if temperature is not within compensation
range for the selected product.
B (TP4): 2 position jumper terminal; NOT USED
C (TP3): 2 position jumper terminal; NOT USED
V (TP2): 2 position jumper terminal; momentarily SHORT to simulate 1000 pulse input signal.
+L.E.D.: Illuminated indicates temperature out of range high.
- L.E.D.: Illuminated indicates temperature out of range low.
A L.E.D.: ALARM INDICATOR: Illuminated when temperature goes out of range for the selected product.
I L.E.D.: INPUT INDICATOR: Flashes at the input signal frequency (at high frequencies, the L.E.D. will appear
constantly illuminated)
O L.E.D.: OUTPUT INDICATOR: Flashes at the output signal frequency (at low frequencies, the L.E.D. will be very
dim)
SENSITIVITY
If electrical noise is generated near the turbine or signal cable, it can overwhelm the real signal and cause erratic
performance resulting in large errors. To prevent this condition, the sensitivity must be reduced. The sensitivity
adjustment should be made at the lowest expected flowrate. Turn R15 completely counter-clockwise. With the
low flow through the turbine, slowly adjust R15 clockwise until the totalizer increments, then increase R15 slightly
clockwise again. In the nominal R15 position, the arrow indicator will be in the 11:00 o’clock position
