5.3. Electronics
The dispenser control shall meet the exacting requirements of simplicity and convenience and depends
on the hanging up and lifting of the dispensing nozzle.
ADP1/T, ADP2/T, ADP1/L electronic counter of an up-to-date design with central processor board
equipped with a high efficient microprocessor. The configuration of the counter and its modes of
operation are adjusted by more than seventy parameters. The counter is provided with a self-diagnostic
system. The counter outlets control the motors, valves, signalling circuits and vapours exhaustion. The
electronic counter processes the impulses coming from the impulse sensor and transmits them to the
display, which displays the dispensed volume, its price and a price per a volume unit. In case of power
failure or voltage drop the data displayed remain for 30 minutes at least.
Counters ADP1/T, ADP2/T, ADP1/L are standardly equipped for electronic meter calibration (Electronic
Calibration of Meters – EC) and per request by ATC – (Automatic Temperature Compensation)
Electronic Calibration of Meters (EC) enable to correct measured volume by designed declination in
operation range -5,00 % to +5,00 % of recognised meter non accurancy by step of 0,05 %.
Automatic Temperature Compensation (ATC) is designed to compensate temperature expandity of
dispensed medium based on measured temperature during dispensing. For temperature measuring is
used approved certified temperature sensor – resistance temperature sensor PT 100, in fuel dispensers
V-line 899x.xxx/S build in entering angle to pumping monoblock and in fuel dispensers V-line 899x.xxx/P
build in pipeline after the filter unit.
Calibration tablets for ATC on designed medium (type of fuel) can be integrated into SW of electronic
counter by customer request. Setting of calibration EC or ATC is provided by using of service keyboard
KL-SERINF and setting of proper calibrating switches DIP on body of electronics counter as per
instructions described in manual of electronic counters ADP1/T, ADP2/T, ADP1/L.
Providing of calibration is allowed to authorised person, only. The DIP calibration switches must be fixed
by plomb after calibration finish.
Displays: LCD type with BACK LIGHT illumination
LCD displays with BACK LIGHT DISPLAY (BLD) illumination are used especially for their good
readability. The duration of data holding on the display after supply voltage failure is 30 minutes at
least. Decimal point on BLD display devices is represented automatically in accordance with the setting
of parameters.
Lighting
LED diodes are used for the illumination of displays at dispensers.
ON / OFF switching of the illumination is automatically carried out with the activation of electronics.
Totalizer: non-resetable electronic counter of dispensed volume and its price – 11 digits – or non-
resetable electromechanical counter of dispensed volume – 7 digits.
Electronic counter of ADP1/T, ADP2/T, ADP1/L series operates with a 2-channel impulse generator
producing 2x 100 impulses per 1 dm
3 . The HW and SW counters of the ADP1/T, ADP2/T, ADP1/L series
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 cover of 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 or proportional electromagnetic valves ensure the closing of
flow and exact dispensing of the preselected volume and smooth initiation of dispensing.
The fuel dispensers can be equipped with ADAMAT filling automatic equipment – payment terminal. This
equipment enables dispensing and payment of the product by means of contactless, magnetic and chip
cards including receipt printing and 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 with
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.
