enable high metering accuracy and the application of the electronic calibration using the 2-channel
impulse generator.
The local electronic preselection system in IP67 design is integrated into the counter case. The
preselection enables the Customer’s preselection of the exact volume or the price of the product to be
dispensed. The two-stage electromagnetic valves ensure the closing of flow and exact dispensing of the
preselected volume / price and smooth initiation of dispensing.
The fuel dispensers can be equipped with ADAMAT paymant terminal (filling automatic equipment). This
equipment enables dispensing and payment of the product by means of contactless, magnetic and chip
cards including receipt printing. This equipment undertakes simultaneously all functions of the dispenser
electronic counter for non-public and public dispensing. The electronics of the filling automatic
equipment can be complemented by the ADP1/T, ADP2/T, ADP1/L electronic counter for public
dispensing.
The fuel dispenser is connected through a communication line to the control system, which controls the
operation of the whole filling station (releasing of dispensers, volume preselection, unit price variation,
self-diagnosis, etc.). The dispensers can be operated even at the filling stations without any control
system – i.e. in serviced operation.
Circuit diagrams for the connection of individual dispenser types to the switchboard of the filling station
are in enclosures.
4.4.1. Communication to the control system
The dispensers are equipped with ADP1/T, ADP2/T, ADP1/L electronic counters, which are able to
communicate to POS Win control systems. A communication serial interface RS 485 or a communication
standard IFSF LON are used for the communication of electronic counters to the superior control system.
Communication to different control systems shall be consulted with the manufacturer of the dispensers in
advance.
The fuel dispensers connected to the control system can be operated in the mode of volume preselection
or the financial sum preselection from the control system (
the dispensers have to be equipped with two-
stage or proportional electromagnetic valves ).
The POSWIN control system (POS Win EURO) enables the process control and the sale of goods according
to stock cards (999 999 items in 99 groups) including storage facilities. The control systems communicate
with the dispenser on the principle of the bus interface RS 485. They combine the basic functions of the
filling station, i.e. sale of fuels, sale of dry goods and their filing. The POS system is also able to operate
even as a multi-cash one, i.e. its individual parts can be interconnected in the communication SW
network, two backoffices and three tills, if more than five backoffices or tills are connected, a server has
to be included.
4.4.2. Elektronics fuel dispenser V-line 899x.xxx/LPG/M HYBRID
Fuel dispenser V-line 899x.xxx/LPG are standardly produced with an electronic counter Beta Control
type ADP2/T-LPG.
Counter ADP2 / T-LPG LPG dispensing enables management or conventional fuels eg. Petrol and diesel.
For the measurement output are used mass flowmeters with MODBUS protocol. ADP2/T-LPG is maximally
compatible with the basic version counter ADP2 / T. These include electronic totalizer, operating modes
AUTO / MAN, parameter settings etc. Preserving compatibility allows service technicians to quickly and
easily adjust the operating parameters of the dispenser.
4.5. Vapour recovery system
Fuel dispensers ADAST POPULAR type line V-line 899x.xxx are supplied in the following modifications of
petrol vapor recovery systems :
1 System VRC-M Vapour Recovery Control – Mechanical - control the flow of vapor by
hydromechanical proportional valve integrated into nozzle (Elaflex).
2 System VRC-E Vapour Recovery Control – Electronic – control the flow of vapor through the
proportional solenoid valve directly controlled by an electronic control unit
dispenser (single-chip microcontroller electronic counter).
