1.5.1 SAFETY CHECKLIST
•It is obligatory that this checklist be fully complied with during all work at the
petrol station, particularly construction or repair work.
•It is the duty of the contractor to ensure that all workers employed by him obey
each and all of the relevant laws, directives and other regulations.
Areas where special caution is required
•Theinsidesoftanks,tubes,dome shafts, filling shafts, change overshafts,vessels
and dispensers.
•All areas in which fuel vapour that is heavier than air can accumulate, e.g. fuel
separator, draining shafts, low located rooms, cellars, excavations, pipe trenches
etc.
•Theareasaroundtheoutletsof tank ventilation pipes, especially duringthefilling
phase.
•All areas near dispensers, tanker lorries and other vehicles while they are being
tanked up, and particularly when there is a lack of wind.
•A radius of 1.0 metres around petrol carrying pipes, as well as pipes that are not
vapour free.
•Silt traps.

Introduction WWC T1 Set Up & Maintenance Manual
1.5.2 DUTIES OF THE EMPLOYEES
•To ensure optimal accident prevention in our company, in addition to general
rules applying to worker’s protection, it is necessary to take into account all the
national protection of workers legislation and to actively support all measures
which enhance safety standards.
•Itisanemployee’s duty to followallcompanydirectivesregarding the prevention
of accidents, unless such directives can be proved to be unfounded.
•Employees should not follow any instructions that go against safety standards.
•Employees are only permitted to use equipment for its original purpose, and this
is defined by the company alone.
•If an employee detects equipment that is deficient in terms of safety, he shall
eliminate this deficiency immediately. If such safety rectification is not part of
his defined area of activities, or if his knowledge is insufficient to carry out such
work he must immediately inform his superior about the detected safety
deficiency.
This equally applies to:
1) Work Materials which have not been correctly packed or correctly marked in
order to meet safety requirements.
2) Work Methods or work processes which have not been correctly coordinated
or controlled in order to meet safety requirements.
3) Where dangerous activities are carried out by several persons, the need
for a permanent faultless communication between them in order to avoid
dangerous events shall require the appointing of one person in order to carry out
overallsupervision.
1.5.3 HAZARDS
Prior to starting work, the dispenser must be isolated (i.e. entirely disconnected
from the mains supply) and the mains supply switch locked in the OFF position.
The submerged pump (if applicable) and control signals from the dispenser must
also be isolated. This is done to provide safety for the technician. As a further
precaution, switch off the mains supply in the service station shop and place a
clear notice on the switch to avoid it being turned on again inadvertently.
WARNING : THE CONNECTION AND DISCONNECTION OF
ELECTRICAL CONNECTIONS MAY ONLY BE CARRIED OUT BY
QUALIFIED PERSONNEL AUTHORISED FOR SUCH ACTIVITIES.
WORK IN DANGEROUS AREAS MUST BE MADE SAFE BY
OBSERVING ALL THE NATIONAL SAFETY REQUIREMENTS IN
FORCE.
It is not permitted to put a fuel dispenser into operation before an authorised
officialhasinspectedit and releasedit.Thisdependsupon the nationalregulations
in force.
Dismantled packaging and cladding must be stored in such a way as to avoid
damage to components or injuries to persons. Covers that can be opened, such
as the calculator housing, should be handled with care. Ensure that the retaining
catch is placed in the correct position to prevent the cover falling onto the head
of the service engineer or other persons in the area.

At unattended service stations, every end-user should be able to read the User
Instructions. They should be visible on a notice board or integrated into the DIT
and should be sufficiently well lit so that they can be read at night.
At unattended service stations break away couplings must always be used to
reduce the danger caused by a motorist driving off with the nozzle still in the
tank.
1.5.4 WARNINGSIGNS
The following warning signs are fitted as standard, on the dispenser, however
they may vary according to individual country requirements or customer
specifications.

2 PRODUCT INFORMATION
2.1 System Description
The WWC (World Wide Calculator) is a ‘measuring system’ built to conform to the
international recommendations specified in the document OIMLR117 Edition 1995.
The WWC is also a peripheral within the different Tokheim filling station systems. As
such, the WWC software and hardware can be configured without modifying the
characteristics of the measuring system.
The WWC is based on the CoCa (Today’s Common Calculator). The hardware has been
re-designed to keep up with technological advances and to allow more flexibility in the
extended scope but the main controlling parts are structured in the same way as the CoCa.
The software is similar to the CoCa software with adaptations to the new hardware and
updated functionality on the kernel side to ensure the re-use of all application parts, with
only minor changes. For further details, refer to the separate documentation, WWC System
FunctionalDescription.
2.1.1 OPERATING PRINCIPLES
The WWC T1 Calculator has been built around a central microprocessor which
controls several other microcontrollers for the input and output devices e.g.
counters, indicators, peripherals etc.
For each road side (right and left) of the metering pump/dispenser, the double
pulse signals from one or more pulsers, mounted at mechanical volume meters,
are checked and the information is counted and displayed on the corresponding
transaction indicator unit.
One calculator can simultaneously control two deliveries - one at each side of
the dispenser. The data is checked through several hardware and software
security systems.
Connectiontoa fillingstationcontrolsystem (self-servicearrangement)is possible
through data communication. The calculator can also function as a standalone
unit whereby information is transmitted to the WWC via a remote control unit.

2.2.1 EXTERNAL POWER SUPPLY
The external power supply contains the following components:-
•Apower distribution unit High Voltage Unit (HVU) including transformer
•A rechargeable back-up battery
2.2.2 MAINBOARD
The mainboard (version 3++) includes the calculator module and the Hydraulic
Controller Module (HCM):-
•The calculator module is able to manage two deliveries independently (one on
eachroadside);controlthedeliveries;maintain the volume and amount counters;
control the transaction displays and hydraulic units; and communicate with the
self-service device.
•The HCM is responsible for supporting the hydraulic interface by checking the
volume pulser devices; counting and checking the two incoming line volume
pulses; controlling the motor and valves and updating the electro-mechanical
totalisers.
Themainboardprovidesalltheinterfacesrequiredto drivethe‘low-end’ hydraulics
without the need for an I/O board - single product and twin functionality (two
motors, two pulsers, four valves).

Product Information WWC T1 Set Up & Maintenance Manual
Since the release of Version 3 of the mainboard, the NBB board has been
eliminated and the serial nozzle bus is directly controlled by the mainboard.
Two optional modules can be directly connected to the mainboard (piggy-back):-
•The COM (Communications adapter) is used to interface the hardware to the
various self-service devices.
•The IEB (I/O Extension Board) is used to connect the peripherals often used in
Single/Twin configurations e.g. preset keypad, simple set up and configuration
keypad.
2.2.3 I/O BOARD (VERSION 3++)
The I/O Board is a level converter and control signal distributor for one to four
single product hydraulic units.
2.2.4 TRANSACTIONDISPLAYS
The transaction displays indicate the transactions on each side of the dispenser
showing the volume, amount and fuel price of the actual delivery. For each
side, it is possible to add a ‘slave’ display. Two different types of display are
available:-
•CSD-L : Liquid Crystal Display device
•CSD-F : Electromechanical Display device (Ferranti)
2.2.5 USERACCESS DEVICES(UAK/UAM)
User Access Devices are used to set the basic set up and configuration for the
calculator and optional devices via an integrated keypad module for service
engineers (UAK) or via an infra-red remote control unit (UAM/IRM). It is
possible to get a readout of totals, errors and service parameters. Either the
UAK (also used for VRC configuration and calibration) or the UAM/IRM can
be used but both devices cannot be used in parallel.
2.3 Different Configurations
With the main components, the following configurations are possible:-
•Standard dispensers with up to four single products (refer to section 2.3.1)
•Low end dispensers: single product or twin configuration, super high speed single-sided
(Fleet) (refer to section 2.3.2)
In addition to the above configurations, the following options can be added via the Dipnet:-
•Vapour Recovery Controller Board (refer to section 2.3.3)
•Option Controller Board (refer to section 2.3.4)
•Hydraulic Option Modules (refer to section 2.3.5)
•I/O Extension Board (refer to section 2.3.6)
