1.2 Product Description
The VST Fuel S-810 Fuel Management System is a self- contained, micro-processor based, control and data
acquisition system designed to authorize, monitor, and record fuel dispensing operations. The VST Fuel
S-810 consists of an Island Mounted Data Entry Terminal (DET) which has the capability of simultaneous
control and monitoring of from one to four dispensers. Access input device options for the VST Fuel S-810
are available for magnetic cards, optical cards, touch buttons, or keys. Models are also available which use
keypad entry only and do not require an input device.
Operating the VST Fuel S-810 is straightforward. The user inserts his input device or “keypad entry only” into the
VST Fuel S-810 and enters the required information on the keypad; usually a PIN number and odometer
reading, etc.. If the input device and the entered information are valid, the VST Fuel S-810 applies power
to the requested pump, allowing the user to dispense fuel. At the completion of fueling, the VST Fuel
S-810 transmits transaction information to its output devices and stores the information in its transaction
memory for later recall. The VST Fuel S-810 will hold up to 1000 transactions in memory for
downloading.
The VST Fuel S-810 Fuel Management System has the capability of operating with a wide range of output devices,
which include printers, modems, personal computers, and other devices which are RS-232 or RS-485
compatible.
The various system operations for control of the VST Fuel S-810 and the generation of reports from the VST Fuel
S-810 are thru priority VST Fuel Management, Inc. software. These commands may be issued locally from
a personal computer or remotely by dial-up communications from a personal computer, , or other serial
communication device. Refer to the Operators Manuals and Reference Manuals for additional information.

3.1 Mounting the VST Fuel S-810

 VST, 2010 7

First, a spot must be selected that is convenient for the users of the system and is appropriate from a wiring point of
view. Refer to Figure 1 for mounting location restrictions. Also refer to the National Electrical Code for
specific information on the location of classified areas in and around service stations and fuel dispensing
equipment. Pay particular attention to the layout of conduit runs and the placement of ac conduit and low
voltage conduit. Care should be taken to provide as much isolation as possible between these wire/conduit
runs and any sources of electrical noise.
The VST Fuel S-810 (DET) may be mounted using either of two methods. The first method is mounting the DET
on the top of a 2 inch pipe x 55” (approx.) height. The DET is simply screwed onto the pipe and after
being positioned for operation the two set screws in the mounting hub are tightened to prevent the DET
from turning during normal operation. The second method consists of removing the mounting hub
normally supplied with the DET and using the gasket and bolts to fasten the DET to the VST Pedestal. The
VST Pedestal must be anchored to the island using six 1/4 inch bolts and appropriate concrete anchors.
Refer to Figures 2 and 3 for detailed information on the space requirements and the bolt pattern required for
mounting the pedestal. Note that the suggested clearance requirements in Figure 2 are for operation and
service of the VST Fuel S-810.

3.2 Conduit installation
Conduit must be installed for the VST Fuel S-810 wiring. Refer to the National Electric Code and applicable local
codes for specific requirements. Generally, rigid metallic conduit is recommended for all wiring due to its
electrical noise shielding and durability characteristics. Other types of conduit may be used as allowed by
the National Electric Code and applicable local codes if proper precautions are taken in its application.
Separate conduits are required for the ac circuits and for the low voltage circuits. Shielded cable is
recommended for all low voltage circuits.
4. VST FUEL S-810 INSTALLATION

4.1 Wiring Requirements
The wire insulation must be oil and moisture proof, using THW, THWN, or equivalent insulation as defined in the
National Electrical Code. All VST Fuel S-810 low-voltage wire size is to be minimum AWG #18 stranded
shielded cable with the shield grounded at one end only. AC wire size is to be minimum AWG #14.
All wiring should be either color coded or numbered to facilitate connection of the wire ends.
CAUTION:
Do not use non moisture, non oil-proof, or standard house grade wire.


4.2 Wire Manufacturers
There are several manufacturers of wiring, any of which produce wire and cable that will work satisfactorily, The
following wire manufacturers' products have been used in conduit on previous systems with good results.
Alpha Wire Corporation; Elizabeth, New Jersey
Belden Electronic Wire and Cable; Richmond, Indiana
Chester Cable Company; Chester, New York
Coleman Wire and Cable Company; Chicago, Illinois
General Electric Vulkene Wire
4.3 Dispensers/Pumps
A. GENERAL
VST Fuel S-810 systems are designed to operate with most commercial type fuel dispensers or pumps. The
dispensers and/or pumps are normally provided by the user or qualified contractor.
For most efficient system operation, dispensers/pumps should be equipped with electric resets. This feature
simplifies control interfacing and, also, helps eliminate false counts during the dispenser computer reset
cycle.
 VST, 2010 11

The dispensers/pumps must contain a 1, 10, 100 or 500 count/gallon pulse transmitter and a Single Pole Double
Throw (SPDT) or Double Pole Double Throw (DPDT) switch that operates when the dispenser/pump is
turned on and off. This switch is used to generate a fueling-complete signal when turned off.
Each dispenser must have a junction box of sufficient volume. See Table 1.

and drawings are provided in this section to assist installers with wiring data.

B. VST FUEL S-810 INTERFACE WIRING

1. Typical dispenser-to-VST Fuel S-810 field wiring diagrams are included in this section (see drawing). The VST
Fuel S-810 connections are shown in the drawing as they appear on the back of the VST Fuel S-810 with
the cover removed. (Installations may vary from this concept due to wiring codes and other circumstances.)
Wiring diagrams of dispensers are used as examples only and in no way imply that the units used with the
system must be rewired to conform with the drawings. Dispensers are shown in all drawings at the end of
fueling with the operating handle in the off position.
2. Install all interconnecting wiring using the most applicable local wiring codes and reliable installation methods.
Wire should be installed in rigid conduit buried in a trench. When planning wire runs, the following
specifications apply:
a. Use Table 1 and the National Electrical Code to determine size of conduit required for the number
of conductors.
b. When possible, install at least 25 percent spares for expansion and maintenance.

CAUTION:

NEVER RUN AC OR OTHER EQUIPMENT WIRING WITH VST FUEL S-810 LOW-VOLTAGE WIRING
UNLESS IT IS IMPOSSIBLE TO AVOID SUCH WIRE RUNS. FAILURE TO COMPLY MAY CAUSE
MALFUNCTION OR POSSIBLE EQUIPMENT DAMAGE.

c. Never run ac or other manufacturers' equipment wiring with VST Fuel S-810 wiring unless it is
impossible to avoid such wire runs. In these cases, shielded cable with outside insulating sheath
must be used for low-voltage wiring. The shield must be grounded at one end only. Insulate the
ungrounded end to prevent shorting to conduit or other wiring.
Note: Shielded wire should be used only if authorized by the applicable electrical codes.
C. DISPENSER WIRING
1. One single-pole interpose relay is provided for each dispenser. Interpose relays are located inside at the rear of
the VST Fuel S-810 housing. (See Figures 4-8 for interpose relay wiring) Relay contacts are rated at 1/3 hp
(115 Vac @ 6 amperes, 230 Vac @ 3 amperes).
2. Terminals are provided at the rear of the VST Fuel S-810 for wiring connections to the control interpose relays,
for wiring connections to the pulse transmitters, and for wiring connections to the handle switches. A
three-wire 115/230 Vac, 50/60 Hz. line input is required for ac power to the VST Fuel S-810. Screw
terminals are located at the rear of the VST Fuel S-810 for the ac line connections.
 VST, 2010 13

3. The interpose relay contacts are normally wired in series with the operating handle switch, reset motor switch, or
similar control circuit of the dispenser. Take care to ensure that the dispenser is shut off and no product can
be withdrawn whenever the interpose relay contacts are open.
4. Submersible Pump System. When controlling submersible pump systems, attention must be given to pump
control and the dispenser control . The submerged pump is turned on by the first dispenser that is enabled
for a given product. This control is accomplished typically through a relay network that is normally not
associated with the VST Fuel S-810 system. Once the pump is running, fuel can be withdrawn from any
one or all of the dispensers associated with that pump unless each dispenser hose is provided with
individual control. This control may be implemented through the use of electrically operated solenoid
valves.
5. Pulser Wiring. Each dispenser, pump, or hose to be controlled and monitored by the VST Fuel S-810 system
requires a pulse transmitter (pulser). The pulser should be a 1, 10, 100 or 500 pulses per gallon resettable
type.
6. Run Circuit or Fueling-Complete Switch. This switch is used for product count enable and for a fueling complete
signal. This switch normally is part of the electric reset. If the proper switch is not available, a relay may be
used. The switch or relay contact allows the pulser to count into the VST Fuel S-810 input only after the
dispenser computer has been reset to zero. This prevents false counts from the pulser into the meter input
during the reset cycle. The switch, in the off position, provides a contact closure to the VST Fuel S-810 to
indicate that fueling has been completed.

 VST, 2010 14


4.4 Communications

VST Fuel S-810 systems are designed to interface to serial communication devices. Generally the serial device is a
printer, a modem, or a personal computer. Connection to these devices are at the removable terminal strip
on the RS 232 or RS 485 boards mounted on the MotherBoard inside the VT-Fuel 810
(See Figure 15). Low voltage wiring is used to make these connections. A communications grade of shielded cable
suitable for RS 232 or RS 485 is recommended (#24 AWG minimum, twisted pair, low capacitance). Be
sure to ground the shield at one end only.
The following figures (Figures 9-14) show typical installation connections for several devices. Specific devices may
require jumpers on some of the control signals that are not required for the operation of the VST Fuel
S-810. Usually connecting the communication device's DTR signal back to the DSR, DCD, and CTS
signals will satisfy any protocol requirements for printers and personal computers. Modems need to be
configured in the answer mode with the appropriate baud rate. The configuration should be stored as the
default mode of the modem on power up to insure that it will operate without intervention. Figure 12 shows
the minimum field wiring required for a modem. The additional control signals (CTS, DCD, RTS, and
DTR) may be connected on a one-for-one basis if desired (See Figure 13). The support of these signals is
limited to providing the correct signal level for operation of the modem.

5. VST FUEL S-810 WIRING VERIFICATION
5.1 General
In order to verify the wiring it is convenient to have the VST Fuel S-810 operational (ac power applied) and be
familiar with some of the basic built-in diagnostic tools. This section is a brief explanation of the built-in
diagnostics. These diagnostics may vary for specific systems, but will generally contain at least those
shown below. The Configuration switch definitions may also vary for specific systems. If there are
differences from those shown, refer to the applicable reference manuals for each specific system.
DIAGNOSTICS CHECK: To access the diagnostics feature of the VST Fuel S-810, the configuration switches
located on the Motherboard must be set as follows (See Figure 15):
Switch # 8 set to ON
After making the necessary switch changes, press the RESET button on the Motherboard, close and lock the front
panel of the VST Fuel S-810 (See Figure 15). The display on the front panel should be as follows:

 VST, 2010 15

You can now perform the diagnostic tests from the keypad on the front panel of the VST Fuel S-810. Each of the
following diagnostic tests are engaged by keying in the number of the desired diagnostic routine. To go to
the next diagnostic routine or to terminate the current one, press CLEAR ENTRY.
DIAG # 1 DISPLAY DIAGNOSTIC: This test is performed to insure that all the elements of the display are
functioning correctly . When this diagnostic routine is engaged, the display will start scrolling the complete
character set and will continue until the CLEAR ENTRY key is pressed.
DIAG # 2 KEYPAD TEST: The keypad test is used to check the functions of all the keys on the keypad. The
test is performed by pressing each key and checking the corresponding display. To exit this diagnostic
routine, press CLEAR ENTRY.
DIAG # 3 READER TEST: The reader diagnostics checks the reader to insure accurate reading of the input
devices (cards, keys, or touch memories). An input device is inserted into the reader, and the display will
show the information from the device. The information on the device is then compared against the
displayed information to test for accuracy. To exit this diagnostic routine press CLEAR ENTRY
DIAG # 4 PUMP CONTROL RELAY TEST: This diagnostic is used to check the pump control relays, to
insure that they will energize upon command from the system and will control the correct pump. When
Diagnostic # four is selected, the display will change to the following:
SELECT PUMP
When you press key 1 the display will change to the following:
1 2 3 4 PUMPS <---- The four pumps.
1 0 0 0 <---- The 1 indicates ON,
the 0's indicate OFF
You could have pressed a 2, 3, or 4, instead of the 1. The number of the pump you press indicates which pump you
are trying to energize. As each pump is energized, the 0's under the pump number will change to 1's. To go
to the next diagnostic press CLEAR ENTRY.
DIAG # 5 PULSER DIAGNOSTICS: The pulser diagnostic is used to check the interface of the system to
the pulsers on the pumps. The pump BYPASS/NORMAL switch must be in the BYPASS position to
perform this test. Pressing key 5, ENTER will cause the display to change to the following:
1 2 3 4 PULSERS <---- Pulser numbers.
0 0 0 0 <---- 0 = OFF, 1 = ON
As each pulser is operated (by pumping fuel), the 0 under that pulser number will alternate between 0 and 1,
indicating that the pulser is working. To exit this diagnostic routine press CLEAR ENTRY.
DIAG # 6 HANDLE SWITCH DIAGNOSTIC: The Handle Switch Diagnostic is used to test the operation
of the dispensers' handle switch, and the interface to the ESI-FUEL 810.. The pump BYPASS/NORMAL
switch must be in the BYPASS position to perform this test. Press 6, ENTER and the display should
change to the following:
1 2 3 4 PUMP SWITCHES
0 0 0 0 0 = SWITCH OPEN, 1 = SWITCH CLOSED
The 0 indicates an open circuit. As each pump switch handle is turned on the 0 for that number pump will change to
a 1. To exit this diagnostic press CLEAR ENTRY.
 VST, 2010 16

Configuration Switch settings:
From the following descriptions of the switch functions, you will have to determine the correct position for each of
the eight switches. For the initial set-up all should be placed in the OFF position. The configuration switch
is located on the VST Fuel S-810 Motherboard (See Figure 15). Note that anytime the switch positions are
changed the RESET button will need to be pressed.
5.2 AC Power

Turn the On/Off switch inside the VST Fuel S-810 to the Off position. Turn on the breaker and measure the ac
voltage at the terminals labeled "L" and "N" on the back of the VST-Fuel 810 (TB-1). The measured
voltage should be approximately 115 Vac. (Or 230 Vac for the 230 Vac Model). Verify that the ground
terminal is connected to a low impedance ground. If the correct voltage is present, turn the Esi-Fuel 810
power switch to the on position. Put the VST Fuel S-810 into the keypad diagnostic mode as explained in
the previous section. Run the diagnostics for the display (DIAG #1) and keypad entry (DIAG #2) at this
time as a general check that the VST Fuel S-810 is functioning.
5.3 Dispensers/Pump Control
Before proceeding, verify that the jumper blocks on the pump interface boards are in the proper positions for each
board (See Figure 16). If they need to be changed, turn the power off and change the jumper blocks to the
correct positions.
For each pump interface board, place the BYPASS/NORMAL switch in the bypass position and verify that the
proper voltage is applied to the pump or dispenser. Do this one pump at a time to isolate and detect any
cross wiring. Verify that the level of voltages on the pulser circuits is approximately 10 Vdc and that the
voltage on the run circuit is 115 Vac only when the pump is authorized and the handle is in the on position.



5.4 Handle Switch/Run circuit

Using the Handle Switch Diagnostic (DIAG #6) and the pump switches in the BYPASS position verify that the
handle switch is detected for each pump. Turn the handles on one at a time and check that only the
indicator for that pump is on. Do this for all pumps attached to the VST Fuel S-810.
5.5 Pulse Transmitters

Using the Pulser Diagnostic (DIAG #5) authorize each pump and dispense a small amount of fuel to verify that the
pulsers are counting properly. Do this for each pump one at a time. Also verify that the pulsers are
connected to their respective pumps.
5.6 Communications
Checking out the communications circuits require the communications boards addresses and jumpers to be in the
proper positions. Refer to the system documentation to verify that all jumpers are configured correctly (See
Figure 17). Refer to the Operators Manual for information on communicating with the VST Fuel S-810.
