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 TRANSACTION DISPLAYS
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 USER ACCESS 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)
