1. INTRODUCTION

This manual describes the service of Wayne Vista series blending and non-blending dispense rs that have a "3" in the prefix of the model number. For example, 3/V390D1/GQUY. Again, these dispensers can be identified by their model which begins with “3/V”, hereafter, referred to as 3/Vista models. The basic troubleshooting methods and service theory will remain the same for all models of dispensers which satisfy the above definition. Any information which is specific to a particular model of dispenser will be shown as specific in the text.

Non-blending dispensers included in this manual are the 3/V387, 3/V388, 3/V389, 3/V390, 3/V399 and 3/V490 models. Non-blending dispensers do not combine base products. These dispensers are multi-grade dispensers, except for the 3/V387 single grade model.

Blending dispensers included in this manual are the 3/V580, 3/V585, 3/V590, 3/V591, and 3/V595 models. Blending dispensers combine the ba se products to provide a blended grade or grades. Blending di spensers have two base products labeled LO and H I. These base products ma y be dispense d individually and/or combined into one or more blended grades. The 3/V591 and 3/V595 models also have an additional single-product (unblended) grade, however, the 3/ V595/U does not.

3/Vista series dispensers have a new computer - and associated boards - and a sales display board mounted on the back of the new bezel.

The new computer in 3/Vista series dispensers controls the hydraulic module that was newly designed and introduced in the 2/Vista series. The hydraulic modu le consists of the iMeter Module and the Intelligent Pulser. The iMeter Module is two meters in one assembly and contains the Intelligent Pulser. .

2. OPERATION

The ope ration fo r all 3/V ista se ries dis penser s is simi lar , ex cept wher e disti nguished below between lift-to-start and push-to-st art mo de ls.

Before the dispenser will reset unit prices must be set and an authorization signal must be received, and if a blender model, blend ratios must be set. The unit prices, authorization, and blend ratios can be manually set at the dispenser for stand-alone operation, or from a control system, after first setting the fueli n g point ID .

The above requi rements are discussed in deta il in t hi s section. Once they have been satisfied, the dispenser oper at es as de scribed in the followi ng sections.

2.1. LIFT-TO-START MODELS

• When the no zzle is r emov ed f rom the n ozzl e bo ot an d th e l ever is li ft ed, t he co nst ant +5 VDC that the computer supplies to th e nozzle switch goes to g round. This signals the computer to be gin its reset cyc le .

• When the di spens er rece iv es a n Authorization signal either fro m the co ntro l syste m or, if stand -al on e, f rom th e di spe nse r, t he cor rect su bmer sib l e pu mp re la y wi ll be e ne rgi ze d.

• The computer p erforms a self test an d flashes eights, bla nks , then resets to z er o s, on the main sale display.

• After the dispenser resets, the proportional flow control valve (or valves if a blender model) is energize d w i th j ust e nough current to barel y open the valve and all ow a slo w flow. After a small amount of fuel has been di s p ensed, the valve is energized with enoug h current to be in the fully open position and allow fast flow. During the sale, the valve will be continuously controlled with the proper amount of current to limit fuel flow rate to a maximum of 10 GPM

, and if a blende r model, provide the correct blend rati o.

• In preset sales, the current received by the proportional flow control valve(s) is reduced to the barely open position ju st pri or to the final shut-off amo unt. The valve(s) is then de-energi ze d when the final amount is reached .

• When the lever is lowered, the nozzle switch goes b ack to the c onstant +5 VDC, the sale is complete, an d th e nozzle is returned to the nozzle boot.

2.2. PUSH-TO-START MODELS

• When the nozzle is removed from the nozzle boot, the constant +5 VDC that the computer suppl ie s to th e noz zle switch goes to ground. At this point, on e of th e l ighted buttons (grade select, cash/credit, or push-to -start , de pe ndi ng model) will flash indicating that one of th e buttons must be pressed.

• When one of the lighted buttons is pressed the constan t +5 VDC that is supplied to the switch goes to ground. This signals the comput er t o begin its reset cycle.

• When the disp en s er r eceives an Authorization signal either from the contr ol system or from the Auth orize switch in the di s p enser, the correct submersible pump r e lay will be energized.

* The maximum allowable flow rate in the United States is 10 gallons per minute.

Page 8

Part No. 920525 Rev A June 2001

• The computer perform s a se lf t est and fl ashes eights, blanks, then resets to zeros, on the main sale displ ay.

• After the dispenser resets, the proportional flow control valve (or valves if a blender model) is energized wi th j ust e nough current to barely open the valve a nd allow a slow flow.

After a small amou nt of fuel has been dispensed, the valve(s) is energized with e nough current to be in the fully open position and allow fast flow. During the sale, the valve(s) will be continuously controlled w it h the proper amount of c urre nt to limit fuel flow rat e t o a maximum of 10 GPM

, and if a blender model, provide the correct blend rat io.

• In preset sales, the curre nt rec eived by the proportiona l flow c ontrol valve(s) is reduced to the bare ly open position just prior to t he fi na l shut -off amount. The valve(s) is then de-energized when the fina l a m ount is reached.

• When the nozz le is re turne d to the nozz le b oot, the nozzle swit ch g oes b ack t o th e co nstan t +5 VDC and the sale is complete.

2.3. SETTING UNIT PRICES

The procedure below is used to set the dispenser unit prices when operating in stand alone mode or when communication with the POS system is disabled. When enabled , th e P OS sys tem will not allow price setti ng at the dispenser.

The pump comput e r rec ognizes code stored in mem ory t ha t de fin es a di spe nse r model and assigns logical nozzle numbers t o the hose positi ons as shown in (Table 2-1). To set unit prices on side 1 an d s i de 2, functions F03 and F04 are accessed usin g th e re mo te control interface. Credit prices on side 1 are set using sub-functions F03.0N while cash prices are set using subfunctions F03.1N, where N is the logical nozzle number. Active values of N are given in Table 2-

1. For side 2, the corresponding sub-functions are F04.0N a nd F04.1N, respec tively.

To set the unit pric e, the correct sub-function is accessed, the uni t price is changed to its new value and the data is saved. To access the desired sub-function, perform the following steps using the remote contr ol. Bold type denotes remote control function; italicized type denotes dispenser response.

Accessing the Unit Price Sub-function for Side 1

4. MECHANICAL PARTS

4.1. NOZZLE BOOT (PROXIMITY “REED” SWITCH STYLE BOOT)

The nozzle boot assembly, used on the dispe nser models cove red in this manual, uses a proximity “Reed” switch and magnet for ON/OFF dispenser activation. The nozzle boot can be assembled in either the Lift-to-Start or the Push-to-Start configuration.

4.1.1. Lift-to-Start Versi on

The nozzle boot switch assembly (se e se ction 10) consists of a proximity reed switch attached to the rear of the nozzle boot casting. A magnet is contained in the Lift-to-S tart lever and when the lever is li fted to the ON position the magnet is brought into alignment with the proxim ity switch, turn ing the sw itch ON. There is no adjustme nt for the switch.

Check the opera tion of the nozzle switch as follows:

1. Authorize the dispenser and remove the nozzle from the nozzle boot. Lift the nozzle hook lev er full y upw a rd to make sure the switch turns O N . An ON switch will be indi cated by the unit price displays of the unselec te d products going OFF or displaying dashes.

2. Lower the Lift-to-Start lever to the down position and check that the switch turns OFF. An OFF switch is indicated by the unit price displays of the unselected produc ts coming back ON .

4.1.2. Push-to-Start Version

The nozzle boot swit ch assembl y (see se ctio n 10)) con sis ts of a prox imity reed switch attach ed t o the side of the nozzle boot ca sti ng and a magnetic act ua tor shaft inserted into a spring-loaded flipper within the nozzle boot. When the nozzle is removed, the flipper rotates and aligns the mag netic shaft with the proximity switch , turn ing th e swit ch ON. T her e is n o ad justm ent fo r the swit ch.

Check the opera tion of the nozzle switch as follows:

1. Authorize th e di spenser and remove the nozzle from the noz zl e boot to make sure the switch turns ON. An ON switch will be indicated by the lighted Push-to-Start bu tt ons and the unit price displ ays bl in ki ng.

2. Insert nozzle slowly i nto the noz zl e boot and check that th e swit c h tur ns OFF. An OFF switch is indicated by the li gh te d Push-to-Start buttons turning OFF and the uni t pr ic e di spl ays sto p bl ink ing.

5. HYDRAULIC PARTS

The following section describes the operation of those hydraulic parts in Wayne dispensers which perform some “act”. Simple flow tubes will not be discussed.

There are four basic hy dra u l ic parts in the dis p e n s er:

• Strainer and Filter

• Proportional Flow Control Valve iMeter

• Ch ec k & Pressure Relief V alve

5.1. STRAINER AND FILTER

The strainer and filter (see Figure 5-1) are mentioned in this document because they may cause the dispenser to deliver slowly. In some cases this may appear to be a service problem. In reality the fil te r shoul d be changed and the strain er cleaned on a regular basis.

Before removing the strainer or filter assembl y, trip the impact valve and turn OFF the circuit breaker for the associated submersible pump.

5.1.1. Strainer

If the underground installation is new, it may be necessary to clean the strainer screen two or three ti mes th e fi rst few days of operation to remove debri s and pipe dope. After this, occasional cleaning of the strainer is all that should be required. The fuel filter s hould be changed whenever the strai ner is cleane d.

The strainer is located above, and held in place by, the filter . After removing the filter, again place suitable container below filter/strainer casting to catch product and sediment, gently pull the strainer downward to remove it from the filter/ strainer casting. Replace or clean strainer screen of any debris and reinstall.

5.1.2. Filter

Like the s tr ainer, in new installatio n s it may be n ecessary to chang e the filter frequently in the first few days of operation in order to ensure proper operation.

The fuel filter is removed the same way an oil filter is removed from a car engine. Pla ce a containe r under the filter to catch the fuel. To in st all the new filter, first apply a film of oil to the gasket and hand turn until the gasket contacts the base. Then ti gh ten one half turn. Open the emergency shear valve, turn the submersible circuit breaker ON and check for leaks.

5.2. PROPORTIONAL FLOW CONTROL VALVE

The proportional flow control val ve (see Figure 5-2) is a pilot-operated, diaphragm sole noid valve. It has three main functions in the dispenser:

• Po sitive shutoff

• Blend ratio control

• Flow ra te regulation

Located between the meter and the hose outlet, the valve is controlled by a 24 VDC pulse width modulated signal. Normally closed, the pilot opens by an amount proportional to the amount of current sent to the va lv e co il. As the pilot raises off its seat, it reduces the pr essure to the back side of the diaphragm causing it to lift off of its seat as well. The same applies to the valve closing; the diaphragm fol lo ws the pilot back to t h e closed position as the current to the coil is reduced for blender models. The computer continually adjusts the current to the valves during a sale based on the desi red blend ratio of the two feedstocks and maximum allowable flow ra te. The high and low products remain separ at e until they are mixed at th e hose outlet in proport ional blender s or at th e outlet valve in fi xe d ratio blenders.

FIGURE 5-2. PROPORTIONAL FLOW CONTROL VALVE. In 3/Vista models the valve is located at the meter outlet.

Page 40

Part No. 920525 Rev A June 2001

5.3. PROPORTIONAL FLOW CONTROL VALVE continued

The pilot opera te d proportional solen oi d val ve performs three basic functions in the dispenser. It provide s positiv e shutoff, regulates the ratio of blended feedstocks, and controls the flow rate through the hydraulic path by limiting the maximum flow rate through a given hose .

The pilot opera te d proportional flow control valve con sists of t w o m ai n pa rts:

• The proportional valve

• The valve coil

The proportional valve is an electrically operated solenoid made up of a body and an operator. It controls all flo w thr ough the dispenser.

The valve coil contr o ls the operator of the valve. The coil is energized wi th a pulse width modulated (PWM) signa l th at send s discrete “bursts” of current at a set frequency level. When the coil receives this signal, the pilot inside the operator reacts to the changing magnetic field and moves up and dow n de pending on the amou nt of current throug h the coil. Th e positio n of the pilot r elative to the pilot o rifice in the diaph r agm controls the amount of flow.

In all Wayne dispensers using this valve, the general order of operation is the same. At the beginning of a sale, the coi l is energized with a minim um current level, allowi ng sl ow product flow to start. After a small amount of product is delivered, the coil is energized with more current to ini ti ate ful l re gulate d flo w. Fo r prese t sale s, the dispen ser wi ll swit ch b ack to slow flow at a pre-deter mined po int.

5.2.1. Flow Co ntrol Valve “Off” No Flow

Flow control valve “Off” or no f low occur s w h en the inlet to the v alve is charged. But there is no flow required from the part ic ular valve as in the instance where a submer sibl e pum p mo to r is running because anot he r fue li ng point is being used. The pilot stays closed al lo w in g pump pressure to build on the back side of the dia phragm, closi ng t he outlet port.

5.2.2. Flow Co ntrol Valve “On” Slow Flow

Flow control valve “On” slow flo w occ urs a t the be gi nning of all sales, and again at the end of preset sales. In this case the coil is energized with current bursts o f s h o rter duration. This allo w s the pilot to slightly move off its seat, allowing slow flow through the pilot orifice leading to the valve outlet, but not relieving enough pressure to cau s e the diaphragm to o pen.

Page 41

June 2001 Part No. 920525 Rev A

5.2.3. Flow Control Valve “On” Full Regulated Flow

Flow co ntrol val ve “On” ful l re gula ted f low o ccur s du ring t he ma in po rti on o f all sales. At this time, the coil is energized with bursts of current of longer duration, pulling the pilot further off it’s seat, relieving the pressure balance, and allowing the diaphragm to open by an amount relative to the distance between pilot and the pilot orifice. The position of the pilot is constantly moving in very small increments based on the signals sent from the computer relative to controlling a specific blend ratio and/or maintaining a maximum flow rate of 10 GPM through a hose. As the computer senses the need to incre as e or decrease the amount of a partic ular feedstoc k, it will send signals to the co i l of longer (to open) or shorter (to close) duration. As a result, the pilot moves up or down causing the diaphragm to follow its movement and achieve the proper amount of flow.

When the delivery is co mpl ete, the coil is de-energi zed , allowing the pilot to return to its closed position. Th is allows pressure to b u ild on the back side of the diaphrag m, forc ing it to close and sea l th e outlet port there by sto pping flow.

5.3. iMETER

The iMeter is designed and assembled around a modular type concept using fewer parts and allowing easier access for service. The iMeter module Figure 5-3. contains two meters in one assembly an d the Inte lligent Pul ser . Each of the tw o meters in the iMe ter module is a posit iv e displacement meter. The pistons in the meter are in-line with respect to one another - one piston is 180° out of phase with the other. In remote dispen sers, the bot to m of the iMeter body is attached to th e filter/s train er casting as shown in Figure 5-1. In suction pum ps, the bottom of the iMeter body is atta ched to the top cover of th e compact pum ping unit. There are no external moving parts on the iMeter. Calibration is accomplished electronically. A procedure for iMet er calibration and Intelligent Pulser opera ti on i s found in Section 3.

5.3.1. Check and Pressure Relief Valve

There are two Check

& Pressure Relief (C&PR) valves located atop the iMeter module under

removable covers, as shown in Figure 5-3. The top mounted location allows for check valve replacement without draining the meter body . Once a delivery is complete and the diaphragm valve i s closed, the pro duct pressure b etween the check valve and the n ozzle will be he ld at the pressure of the last delivery. If the pressure should build up due to temperature rise in the hose or a car runs over the hose, the relief function of the C

&PR valve would relieve the pres-

sure buildup. The relie f va lve is set to relieve pressure between 30-50 psi.

5.4. DOUBLE BUMP TUBING

On 3/Vista di spensers, Double Bump product tubing is used between the iMeter outlet, proportional valve, and hose outlet casting. The double bump connection eliminates the need to torque the compression fittings that were used on the flare tubing.

As shown in the Figure 5-4, the oring fills the space between the "two bumps" , hence the name double bump, and when the tube is inserted into the mating connection, the oring compresses or spreads across this space, making a tight seal around the cylinder. The Safety Clip, while securing the connections, also improves the seal by allowing some flexi bil ity as to exactly where the seal is made.

6. PROGRAMMING FUNCTIONS AND STATISTICS

The Maintenanc e Mode is used to access the functions a nd sta tis ti cs i n the 3/Vista computer. Service technicians can access the Mainte nance Mode by using the Infrared Remote (IR) re m ote control or by running the Service Terminal Program (STP) from a laptop computer. Both of these methods and the descrip tions of the functions and stati sti cs are discussed in detail in this sec ti on.

6.1 IR REMOTE CONTROL

The Infrared Remote (IR) Control communicates with the pump computer by an infrared lin k to the sensor mounted on the dispenser’s sales display board behind the bezel.

The IR remote control has 16 buttons. When the remote control is held close to the infrared e ye (Figure 6-2.) on the display board, it can be used to access dispenser functions and statistics (diagnostics). The remote is used to set unit prices, fueling point numbers, serial or standalone communications, blend ratios, read electronic totalizers and error codes, and perform many other diagnostic and service related tasks via the Maintenance Mode.

Four levels of entry to the Maintenance Mode are listed below. To access the mode, hold the remote control within 12" of the display and press the appropriate key as follows:

for Field Service ent ry using field engineer password press ENTER for Station Manager entr y usin g sta ti on m an ager password press 1 for Operator entry using op era tor password press 2 for Weights and Measure s ent ry using W&M password press CLEAR

The maintenance mode asks for a password twice before allowing access to the maintenance mode functions and stat istics. A 10 second time-out is built into the password en try code. When the word PASS 1 appears on the sales display, enter password and press ENTER. You have 10 seconds to start en te ri ng th e password. The timer rest arts after you press a key. PASS 2 ap pears o n the sales di splay, promp ting you to enter the same password again and press ENTER. The unit price display will show "F - - ", the money display shows the software version number, and the volume display shows the date of the software version. At this point, you can go to e ither Fu ncti ons or t o Stat istics. To e dit or vi ew funct ions, ente r the function number and press ENTER. The f unction n umber will appear in the unit pr ice displa y. To enter the statistics viewing mode press ei ther the UP or DOWN arrow when the unit price is displaying "F - - ". When you enter the statistics viewing mode, the unit price display window shows "S - - ", the money display window shows the current transaction count for side A, and

6.2 SUB ENTRY LEVEL

When you enter the sub entry level, the unit price display shows the function/statistic number in the two left-most digits and the sub level number in the two right-most digits separated with a decimal point. The F or S no longer appear. The following list shows functionality provided at this level. Not all functionality is available depending on user access.

NEXT Advances to the next sub function or sub-statistic within the current function or statistic. If you enter numeric data without first pressing the # key, the system goes to the sub function or sub-statistic of the

corresponding number that you entered. If the number is beyond the range of available subfunctions or substatistics, the maximum sub function or sub-statistic is used.

When you begin to enter numbers (preceded by the # key or not), the non-numeric keys have the following functionality.

CLEAR Backspace key if there is numeric input, other wise returns control to initial screen. ENTER Accepts any numeric input already entered. UP Ignored when numeric input has been entered, otherwise returns control to the sub entry level. DOWN Ignored when numeric input has been entered, otherwise returns control to the sub entry level. # Ignored when numeric input has been entered, otherwise returns control to sub entry level. NEXT Ignored when numeric input has been entered, otherwise returns control to the sub entry level.
