CNG dispensers TATSUNO EUROPE ‐ Quick User Guide

dispenser is not controlled in any way in the manual mode, it is necessary to manually set the fuel unit price on
the dispenser – see section 2.1.6. The amount of gas delivered during one shift is determined by the difference
of values from electronic totalizers – see section 2.1.4 and 2.1.5, possibly from electromechanical totalizers at
the beginning and at the end of the shift.
The
automatic mode
is a status when the dispenser is remotely controlled by a control device (program in PC,
control device, station controller, payment terminal, etc.). The automatic mode allows remotely control
deliveries from the fuel station booth. The booth contains a control device by which the fuel station attendant
releases the dispenser for delivery and collects information about the delivered gas amount and price after the
delivery is finished.
Delivery progress: The fuel station attendant inserts the delivery nozzle into the vehicle storage tank and presses
the START button. Displays are reset (approx. 1.5 sec) and the delivery starts. After the delivery finishes – see
section 0, the attendant hangs the delivery nozzle back onto the dispenser and the customer pays the required
amount in the booth where he/she receives the tax document (receipt) for the delivered gas. After the payment,
the dispenser is immediately ready for next deliveries. Since the dispenser is remotely controlled in the
automatic mode, it is not necessary to manually set the fuel unit price on the dispenser. The correct unit price
is automatically set by the control computer to all dispensers at the fuel station.
Switch from the automatic to the manual mode.
By default, the dispensers are connected and set as it is
expected they should work at the fuel station, i.e. if the fuel station is equipped with a control system, the
dispensers will be set to the automatic mode; if the fuel station is without the control system, the dispensers
are set to the manual mode by default.
In case it is necessary to switch dispensers from the automatic mode to the manual mode – e.g. due to the
emergency in the control system, it is necessary to perform a change in the P12 parameter from 0 to 3 by using
the IR remote controller, see section 2.1.14, and perform the check of unit price settings in the P03 parameter,
see section 2.1.6.
NOTICE
The switch from the automatic to manual mode must be discussed with the service engineer in advance!

PRESET KEYPAD
OCEAN CNG dispensers may be equipped with a so‐called pre‐set keypad enabling pre‐setting the amount or
quantity by the customer directly on the dispenser. The customer may decide before he/she starts the delivery
with what quantity of gas or for what amount of money he/she wants to refill the storage tank.
The pre‐set value may be cancelled by pressing the <
Cancel
> button at the moment when the delivery has not
started yet. It is then possible to set another pre‐set value or fill the storage tank in a classic way without using
the pre‐set.
NOTE
In case the pre‐set keypads are used, it is necessary that the dispensers ate equipped with deceleration valves
that ensure safe deceleration of fuel flow rate before the target pre‐set value.
a) Example of entering the pre‐set in currency units
The customer arrives to the dispenser and wants to refill gas for 10 Euro.
The dispenser attendant pre‐sets the value 10 on the pre‐set keypad – presses the
<€ 5>
button twice.
