INTRODUCTION
1.1 General
This instruction manual is intended to assist the user with the installation of the VST Fuel S-810 Fuel Management
System. Due to wide variations in dispenser/pump wiring and fueling site layout, it is virtually impossible
to provide detailed instructions for each individual installation. This manual provides a general description
of various types of installations applicable to VST Fuel S-810 systems. Installation shall be in accordance
with National Electric Code (NFPA-70), the Automotive and Marine Service Station Code (NFPA-30A),
the Flammable and Combustible Liquids Code (NFPA-30) and applicable local codes. See Figure 1 for a
general diagram of a typical station layout and mounting restrictions for VST Fuel S-810 location.
THE VST FUEL S-810 IS CAPABLE OF MANAGING UP TO FOUR HOSES

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.

a) Examine all components thoroughly as soon as received. If damaged, write a complete and detailed description of
the damage on the face of the freight bill. Have the carrier's agent sign the description.
b) Notify the delivering carrier of damage or loss immediately. This may be done either in person or by telephone.
Written confirmation must be mailed within 48 hours.
c) Risk of loss or damage to merchandise remains with the buyer. It is the buyer's responsibility to file a claim with
the carrier involved.
d) If you need assistance contact your distributor or the VST factory representative.
2.2 Parts Verification
Prior to starting work, make sure that all of the correct parts have been received.
You will also need the following partial list of parts to complete the installation:
1. Pulsers for each dispenser - 1, 10 , 100 or 500 pulses/gallon
2. A Single Pole Double Throw (SPDT) or Double Pole Double Throw (DPDT) switch
activated by the dispenser handle.
3. An Electric Reset (optional).
4. A Junction box of sufficient volume for each dispenser.

3. SITE PREPARATION
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.
