6.2. TROUBLESHOOTING AND SOLVING DISPENSER DEFECTS
When you encounter a problem, first read the "What to do if ..." table (see Table 39) where the most frequently
asked questions of the dispenser users about the problems encountered at the fuel station are described.
In the event of a dispenser defect, the electronic counter that controls the dispenser displays a fault message in
the form of a numeric code. The fault codes for the individual types of electronic counters are listed in the
chapter 6.2.1.
Table 39 ‐ What to do if ...
The dispenser does not respond to the removal of the delivery nozzle and there is no fault message on the display
This means that the dispenser is without the power supply, or the delivery nozzle on the dispenser is poorly
hinged, or that the dispenser is blocked by the control system.
 Check proper hanging of all delivery nozzles
 Check whether pumping made on the dispenser is paid at the cash desk
 If the dispenser is in manual mode, try unlocking the dispenser with the IR remote controller (press "0")
 Turn the power supply of dispenser counter off and on.
 Check the power supply of dispenser, i.e., when the power is turned on the display must pass the test
 Check the position of the circuit‐breaker for the single‐phase power supply 230V of the dispenser in the
main switchboard of the fuel station
 If the dispenser is connected to the control computer, the dispenser blocking may be coupled to a control
system that does not release the dispenser for pumping or blocks the dispenser. Turn the power
dispenser off and on and change the dispenser mode from automatic to manual. If the stand is in a
manual mode, there is a fault on the control computer side.
When the delivery nozzle is lifted, the display is reset but the pump does not start
This means that the dispenser electric motor has not been started. The cause may be the power supply circuit
breaker that is located in the main switchboard or the electrical motor protection disconnected inside the
dispenser.
 Check the position of the circuit breaker of three‐phase supply of the dispenser motors in the main
switchboard of the fuel station
An error message "E18" will appear on the display of the dispenser
This is a dispenser fault message that indicates that communication between the dispenser and the control unit
(computer, station controller, control console, etc.) has been lost.
 check the correct operation of the control unit (turning on the counter, turning on the data converter)
 check the data cable connection
At the beginning of the delivery, the customer removes the delivery nozzle and does not deliver (e.g., because of
opening the fuel tank of the car). After a while the pump turns off. The display shows "STOP".
This is a dispenser report that states that the delivery has been terminated due to interrupting the delivery for
longer than 60 seconds. Hang the delivery nozzle and re‐deliver.
During delivery the delivery is interrupted (e.g., changing the canisters), the pump switches off after a while. The
display shows "STOP".
This is a dispenser report that states that the delivery has been terminated due to interrupting the delivery for
longer than 60 seconds. Hang the delivery nozzle and re‐deliver.
After picking up the delivery nozzle an error message "E30" appears on the display of the dispenser.
This is a fuel dispenser failure report that states that the fuel unit price is zero.
If the dispenser is operating in a manual mode without the remote control, then the unit price is

incorrectly set. Set the fuel unit price, see chapter 4.1.8 and 4.3.
 If the dispenser is controlled remotely, then check the fuel unit price settings in the station controller
(computer, controller). Before each delivery, the fuel price is automatically sent to the dispenser.
