INTRODUCTION

A. GENERAL

The model T350N-P Totalizer/Printer di s plays flow d irectly in engine ering unit s . The model T350N-P utilizes the latest in circuitry design and components. The circ uitry is microprocess or bas ed and perfor ms th e scaling and count i ng w ith only one main circuit board.
The totalized flow is displayed on a liquid crystal display (LCD), and is printed on standard calculator type thermal paper.

B. THEORY OF OPERATION

Model T350N-P is used in conjunction with frequency or pulse generating source such as a turbine flowmeter or other pulse flow transducers. The totalized flow disp l ay m ay b e c alibrated t o indicat e mos t an y uni t of vol u m e, gals., li ters, scf m. , etc. Standard units are factory-calibrated for a standard flowmeter in ga llons. If additional calibration is necessary, the dividing factor may be changed by adjustment of internal factoring switches located on the main circuit board.
The Model T350N-P dis p l ays total flow vi a an LC D dis play an d th er m al printin g device. Printing of th e dis p layed tot al is accomplished by pus h in g the PRINT switch. The printer will show a two-lin e m essage, product d eliver y, ti m e and date, stating count, and finished count. There is a space provided for an authorized signature. When the printer stops, the display will zero and be ready to acc ept a new c ount. If th e PRIN T sw itc h is activat ed d ur i ng a d eli v ery, the coun t will st op and the print er wi ll pri nt th e n ew inform ati on.

INSTALLATION Inspection
All units are completely assembled, tested and inspected at the factory prior to shipment. Upon receipt of the unit a visual inspection should be conducted to detect any damage that may have occurred during shipment.
Physical
The T350N-P s hould be m oun t ed as practicall y as poss ible tak in g into acc oun t disp l ay vis i bil ity, accessibi lit y, etc. Ideal ly the T350N -P should be securely mounted using
ONLY
the supplied shock mounts on a stand positioning the unit 12-18” ab ove t h e d eck, clear of overhead pipes and as remote form the pump mot or as pos s ib le. Adher ence to thes e gu id el ines will si gnificantly en hanc e the trouble free operation of the unit.
Electrical
The T350N-P is designed to operate on the 12 VDC power system of the transport and is “polarity insensitive”. Both the + and – power in puts s hould be obtained in the pump control box. To facilitate testing without having to activate the entire pumping system + input power should be derived from the unswitched 12 V input to the pump control box . Every effort should be ma de to keep the T350N-P isolated as much as possible within the pump control box. In the event transport doesn’t have a pump control box, as is the norm, 2 wires should be routed to the trailer power junction box located at the front of the trailer. Do not
attempt to obtain power by splicing into the light circuit located near the meter. Line drops and fluctuations may affect the operation. Additionally –
not connect a jumper from the T350N-P enclosure and the trailer
do
repl ace the ch oc k mou nts with so lid “Look a-likes”
chassis and do
not available in hardware store. They have solid mounting studs and are not isolating studs as provided by the Sponsler Company.
Signal
The standard T350N-P signal cable is a 2 wire shielded c abl e w ith a MS3102 connector termination which is the industry standard interface for 2 pole pickup coils. The shielding is single ended and should not be altered.

CALIBRATION Sensitivity
The Sensitivity adjusts (R1) should be adjusted at the lowest expected flow rate. Turn R1 completely Counter-Clockwise then slowly adjust R1 Clockwise until the display increments then increase R1 slightly Clockwise again. In the nominal R1 position the arrow indicator will be in the 11 o’clock position.
Calibrati on Fa ctor
The Calibration Factor is derived by taking the reciprocal of the meter’s “K­Fact or” (pulses per gal lon or other d esi red engin eering un it) .
C.F. =
Engineering Units
K-Factor It is desired that ze ro not be dialed as the first digit on the factor switches. The
CF, in most cas es, will start with at l eas t on e z er o. The multip li er s wi tc h on th e fact oring board wil l allow multipl yin g b y 1, 10, 10 0, 10 00, or 10000 to move t he decimal the required digits.
S4 posit i on Multiplier
0 1 1 10 2 100 3 1000 4 10000
Example 1: K-Factor = 230 pulses per gallon Engin eering un it s des ir ed = gallons C.F. = 1/K = 1/230 = .00434782 Multiplier = 100; S4=2,
Fac tor S3=4, S2 =3, S1= 4, S0=8
The electron ic acc uracy can be verifi ed i ncorporating t h e f ollow i ng f or mu la for a timed tes t:
Total Displayed = Frequency X Time in seconds X C.F. Example 2: C.F. = .004348
Time = 1 min = 60 seconds Frequency = 500 Hz
Total = 50 0 X 6 0 X .004348 Total = 130.4 = 130

Field Correction
To adjust the calibration factor to reflect the turbines actual response to the operating conditions apply the following formula:
New Calibration Factor =
Actual Total
X Calibration Factor
Meter Total Example #2:
Actual Total = 50 Meter Total = 52 C.F. = .004348 50/52 X .004348 = New Calibration Factor .9615 X .004348 = .0041806 Insert 4181 into S3 – S0 respectively
In the ab ove e xam p le .9615 den otes that t h e m eter is op erating .38 5% fast and multiplying the present cali bratio n factor (.004348) by the ratio of Actual Total: Meter Total (.9615) reduces the calibration factor 3.85%.
Calibrati on Fa ctor – Change of Calibration Engineering Units
Assume that rather than gallons, liters are the desired engineering unit. Example #3:

TROUBLE SHOOTING
(INTERNAL RAM TEST (Dipswitch pos itio n #9)
The self-test mode allows the totalizer’s microprocessor to per form internal tests on the built-in RAM and ROM. problem is suspected with the totalizer.
The self test feature should be used only when a
To start the self-test, first set the pre-
scale selector switch (S4) to position #9 (self test). To fully test itself, the on-board computer must perform 257 different tests. As
each test is completed, A & B LED’s on the RLC113 PCB will flash. In order to perform the complete test the leds must flash 257 times. Upon completion of the 257 test the LCD display will print ‘Eprom & RAM OK!’. Any other message indicates an error. If no message app ears on th e LCD di splay, it is poss i ble that the dis pl ay b i as c ont r ol is not ad jus t ed properly. To make the display and background darker, adjust the display bias control fully counter-clockwise. Adjusting this control clockwise will make the display and background lighter.
As long as the pre-scale selector s wit c h (S4) is in position #9, the microprocessor will continue to test itself. Leaving the switc h in position #9 is a good way to isolate any transitory problems.
NOTE: Be sure to set the pre-scale selector switch back to the correct position for pr op er operation.

TEMPERATURE COMPENSATION (RLC131 option)
As product flows through the pipeline, a turbine located in the product spins and electrical pulses are generated and sent to the totalizer. The number and frequency of these pulses corresponds to the amount of product flow and the flow rate.
As the product I the pipeli n e heats or cools , the dens it y and vol ume of the product changes. When the volume of product changes, the turbine spins faster or slower since the turbi n e fl ow m et er is a vol u m etr ic m eas uring d evice, even though the AMOUNT (measured by weight) of product is not changed. Temp er at ur e c om pens ation operates by r ead i ng th e t emp eratur e of t he produc t and add in g or subtrac t i ng pu lses bas ed on t h e tem p erature and hence the density of the product.
As long as the product flowing past the temperature sensor is within range of the product, the temperature compensation module will automatically correct for the density of the product. If the product is not within the correct temperature range, or an elec tr ical problem exis ts wit h the temper at ur e probe, the comp e nsation modu l e will n ot c omp ensat e for th e pr oduct and wil l si mp l y op er at e o n 1 1: 1 b asis without compensation.
Whenever the temperature goes out of range for the selected product, the ALAR M LED w ill illu m inate. If the relay opti on is inst alled, an d ext ernal r el ay will be ener gi z ed w h enever th e alarm cond ition exis ts . If jum p er JU 2 is i ns talled on the RLC131 compensation board the totalizer will stop accepting incoming pulses. Any pulses in storage will be outputted since these pulses were accepted wh il e th e unit was not in al ar m conditi on.
An addit ional f eature exis ts if the op erator wis h es to turn off tem p er at ure compensation even if the RLC131 Compensation Module is installed. To turn off temperature compensation install JU4 on the RLC131 module. When installed, no temp er at ur e c om pens ati on exists and in pl ac e of th e pr oduc t temp eratur e on line 1 of the LCD is the message ‘NO TC’.

PROGRAMMING TIME AND USER CONFIGURABLE MESSAGES
Progr am m in g of t h e cl oc k or user defin able mes sages is accompl is h ed us in g t h e external 4X4 programming keyboard. This keyboard must be plugged into the unit before programming can begin.
The Ticket Printing Totalizer contains a built-in real time clock. The time and date inform ati on su pplied by this cl oc k is us ed to time and d at e stamp eac h tic k et during printing. It is important that the time and date information is correct for proper record keeping. Setting the clock begins by pressing the SET CLOCK key. If the clock has never been set, or the battery has just been changed, the time an d d ate inform at i on dis p l ay ed by the cl ock on lin e 1 wi ll b e garbag e. Pressing the CLEAR key will initialize the clock to the default time of 12:00A 01­JAN-80. Clock information can be changed by moving the cursor using the ( ) ( ) keys, to the location containing the data to be changed. Once at the proper location, press the ( ) key to increment the data. For example, if the cursor is under the mont h of MAR and th e ( ) ke y is press ed, th e m onth with c h ang e to APR. Pressing the (v) key will decrement the data at the cursor location.
When the time and date information is set correctly, press the ENTER key to stor e the n ew time and r etur n to the setup menu.
The tic k et pr in ting total iz er h as bu ilt in mem or y that al l ows th e op er at or to st ore a custom message. The user definable message will be printed as the top 2 lines (by 16 characters per line) on each ticket. Each message line can be up to 16 characters long. Any information such as company name, phone number, etc. can be stored. Setting the message begins by pressing the SET MSSGE key. If the message is being set for the first time, or the battery has just been changed, the message information disp l ayed on th e LCD wi ll be g ar b ag e. Pressing the CLEAR key will clear both message lines. Message information can be changed by moving the cursor using the ( ) for proper location, press the ( ) or (v) keys to change the data. Follo wing is a list containing the order in which data is incremented/decremented:
!”#$%¢’()*+,-./ 0123456789:; = ? @ABCDEFGHIJKLMNOPQRSTUVXYZ (cont) [/] _ abcdefghijklmnopqrstuvwxyz
If the first character of a message line is set to a ‘)’, then the entire message line will not be printed. In this way it is pos s ible to skip messa ge lines rather than havi ng bl an k li n es pr i nt ed at th e top of each tic k et.
Once the message information is set correctly, press the ENTER key to store the mess ages and retu r n t o th e s etu p m enu.
