INTRODUCTION

General

The Model T650N Truck Totalizer provides flow totalization in any engineering unit. The totalized flow is displayed via an accumulating 8 digit Liquid Crystal Display (LCD) electronic counter and an 8 digit resettable LCD.

Negatives previously associated with LCD’s - poor cold temperature performance, night clarity & condensation, which is a byproduct of heaters, and incandescent lighting - have been eradicated with incorporation of a low temperature coefficient LCD (-30 develop a precise, reliable totalizer.

Theory of Operation

The T650N initially amplifies & shapes the incoming pulses generated by the turbine’s response to flow. The amplified pulse train is then scaled and divided to produce a totalized display in the desired engineering unit – gallons, liters, pounds, SCF, m sequence. A manual reset function is available if so desired.

Testing

A single switch “System Test” function enables maintenance personnel to quickly and effectively troubleshoot a system failure, thereby reducing costly maintenance time. “System Test” provides a visual diagnostic indication of every critical function of the T650N. With few exceptions, the system failure will be identified by the fault isolation LED’s of the “System Test”.

Calibration

Field calibration is accomplished by incorporating a calibration factor based on the K-Factor of the turbine. A divider switch provides a divisional increment of 10X from 1-10,000. The calibration factor is inserted using 4 BCD switches & the 0-1 dip switch. The calibration factor range is .0001-1.9999. Verification of the electronics accuracy can be accomplished by conventionally utilizing an external oscillator or by depressing the “System Test” switch which applies a calibrated 500 Hz input signal to the system.

Temperature Compensation – Optional

A microprocessor based temperature compensation system designed to correct flow information based on product temperature is available for use in the T650N. The Model 820 Temperature Compensator accommodates up to 8 different products (field selectable via a rotary switch) and accurately calculates the selected product density acknowledging the non-linearity of the temperature probe and the product.

Installation of the Model 820 Temperature Compensator provides access to wireless I.R. communication for data transfer to the Model SP824 portable ticket printer and provides an output for addition of a PCM-100 module for Pump Control.

After market installation of temperature compensation requires minimal expertise and takes less than 15 minutes to accomplish. By installing the 820 TC module, one connector to the 650 factoring board and the flip of a switch, compensated totalization is accomplished.

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. If the packing case is damaged, notify the local carrier at once regarding his liability. A report should be made to the distributor. Carefully remove the equipment from the packing and inspect for damaged or missing parts.

Physical

The T650N Flow Converter should be mounted as practically as possible taking into account display visibility, accessibility, etc. Ideally the T650N should be securely mounted using ONLY the supplied shock mounts on a stand positioning the Flow Converter 12-18” above the deck, clear of overhead pipes and as remote from the pump motor as possible. Although the T650N enclosure integrity is watertight at manufacture, adherence to these guidelines will significantly enhance the trouble-free operation of the unit.

Electrical

The T650N is designed to operate on the 12 VDC power system of the transport and is “polarity insensitive”. Both the + and – power inputs should be obtained in the pump control box. To facilitate testing without having to activate the entire pumping system, + power input should be derived from the unswitched 12V input to the pump control box. Every effort should be made to keep the proximity of the Flow Converter’s input power leads to the pump motor’s winding leads as isolated as practically possible within the pump control box. In the event a transport doesn’t have a pump control box, as is the norm in CO front of the trailer connected to the 12 VDC accessory or Light Circuit.

DO NOT ATTEMPT TO OBTAIN POWER BY SPLICING INTO THE LIGHT CIRCUIT LOCATED NEAR THE METER: LINE DROPS AND FLUCTUATIONS MAY AFFECT THE UNIT’S OPERATION.

DO NOT CONNECT A JUMPER FROM THE T650N ENCLOSURE TO THE TRAILER CHASSIS AND DO NOT REPLACE THE SHOCK MOUNTS WITH SOLID “LOOK ALIKES” AVAILABLE IN HARDWARE STORES; THEY HAVE SOLID MOUNTING STUDS AND ARE NOT ISOLATING STUDS AS PROVIDED BY THE SPONSLER COMPANY.

Signal

The standard T650N signal cable is a 2 wire shielded cable with an MS3102 connector termination which is the industry standard interface for 2 pole pickup coils. The shielding is single ended and should not be altered.

Initial System Start Up Procedure

Assure all Field Terminations are complete, correct and secure. Turn on the T650N and observe that 8 zeros are displayed and the LCD back lighting is on. Depress res et if externa l reset opt ion was selecte d.

Refer to DWG. # SCI-T650N-REV C-TC-INT Open the T650N enclosure and depress “System Test” S9. All LED indicators of the 10 position bar graph D1-D10

should be illuminated except D3 if “1” is selected by “0-1” Switch S2. Also observe that both the LCD counters increment equally. D4, 5, 6, & 7 will blink. Each LED indicates a specific T650N function. The indicators are extensively discussed in the Description Section and in the Troubleshooting Section which should be referenced in the event of a failure of the T650N.
