CONFIGURATION
ATTENTION ! The operation of installation must be do by expert electrician.
DANGER OF ELECTRICAL SCHOCK!

The Control Unit can be set to have all the input or only someone.
With the DIP switch S3 it can be possible select:
1) Presence or not of Electronic key
2) Presence or not of Nozzle Contact
3) Complete bypass of electronic function. In this case the pump is switched ON when the Nozzle contact is close.
The nozzle contact remain the unique control for the pump activation.
With the trimmer TIMER can be set the maximum duration of dispensing
All the configuration are read at start-up. At the start-up the system determines the state of the trimmer TIMER and that of
the DIP-SWITCH of the BYPASS switch S3.
To change the Hardware Settings (Dip Switch And Timer ) proceed as follows:
i. Disconnection power to the control unit;
ii. Open the rear cover of the control unit;
iii. Change the trimmer value (turning with a small flat-head screwdriver) and/or the switches of switch S3;
iv. Close the rear cover of the control unit;
v. Start the control unit again to make the new settings operative.

Is It possible to have a table with state condition by DIP switch S3 and corresponding operational functioning
Table 1.
WARNING ! When there is set the presence of nozzle contact it is necessary when the control unit switch-on that
the nozzle contact is OPEN (nozzle in the nozzle holder)
The TIMER value varies from minimum 7 seconds when fully turned to the left (-) to a maximum 30 minutes when fully
turned to the right (+). This value indicates the max duration of dispensing.
The trimmer TIMER value and that of S3 is only read at switch-on.
2. Procedures for Association of Manager’s Red Electronic Key
To associate the manager’s key (RED key) to the control unit, proceed as follows:
i. Switch-off the control unit;
ii. Press the Start button ( 1 ) and keep it pressed;
iii. Switch on the control unit;
iv. When the indicator LED linked to the keys starts to flash __ __ __ __, release the Start button;
v. Position the Red Key;
vi. The key LED stays lit ________ for 2 seconds, thus indicating that the positioned key has been
stored, and then switches off.
3. Association / elimination of user keys
To associate or eliminate a User key (YELLOW key) to the control unit, proceed as follows:
i. Switch on the control unit;
ii. Position the Manager’s red key (this must have previously been associated)
iii. The key LED starts to flash __ __ __ __ indicating that the control unit is ready to associate one
or more User keys;

iv. If a User key is to be stored in the control unit memory, press the START key ( 1 ). Conversely, to
delete a user I-Button key from the memory press the STOP key ( 0 ). This way, a work session is
opened that will perform the same storage or cancellation operation for all the keys subsequently
positioned.
v. Position the User key;
vi. If reading is performed correctly, the I-Button LED remains on for 2 seconds ________ thus
indicating that the positioned User I-Button key has been stored or deleted and then starts to flash __
__ __ __ in standby for other keys.
vii. If reading is NOT performed correctly, the I-Button LED increases the flashing frequency for about 2
seconds _ _ _ _, and then starts to flash with initial frequency __ __ __ __. If this occurs,
position the User I-Button key again.
viii. If there are any further User I-Button keys, repeat the procedure from point V;
ix. If there are no more User I-Button keys to be stored, position the I-Button Manager key again to
terminate the operation.
4. TOTAL SYSTEM RESET with deletion of all data from EEPROM
This procedure is irreversible and its purpose is to restore the Control Unit board to the state in which it left
the factory, eliminating all the data relating to any associated User and Manager I-Buttons. To perform this
operation, proceed as follows:
i. Switch off the control unit;
ii. Press the Stop button ( 0 ) and keep it pressed;
iii. Switch on the control unit;
iv. When the I-Button LED starts to flash __ __ __ __ release the Stop button ( 0 );
v. Press the Stop button (0) 10 times;
vi. If the Stop button (0) is pressed 10 times within 20 seconds, the internal memory of the Control unit
board will be deleted once and for all, otherwise the Control unit board will return to a standby state,
depending on the setting of the switch S3.
5. Normal Use
Table 1 shows the possible cases we can have with the selection of the DIP switches.
The most frequent cases of configuration of the system are the following four:
Case 1:
- Electronic Key YES
- Nozzle contact YES
In this case the operating sequence is:
1. The operator positions his key and he is recognized by the system and validated. At this moment the key led
lights up ______
2. The operator takes the nozzle and with this consent the pump starts up. The key LED goes out _________
3. The dispensing is done.
4. The pump cuts out because of one of the following cases:
4.1 The operator replaces the nozzle
4.2 The operator presses the Stop button (0)
4.3 All the time setted by the timer passes.
Case 2:
- Electronic key YES

- Nozzle contact NO
In this case the operating sequence is:
1. The operator position his electronic key, he is validated by the system and the pump starts up. The Key Led
flashes for a little time.
2. The operator takes the nozzle
3. The dispensing is done
4. The pump cuts out because of one of the following cases:
4.1 The operator presses the Stop button (0)
4.2 All the time setted by the timer passes.
Case 3:
- Electronic key NO
- Nozzle contact NO
In this case the operating sequence is:
1. The operator takes the nozzle
2. He presses the Start button (1)
3. The dispensing is done
4. The pump cuts out because of one of the following cases:
4.1 The operator presses the Stop button (0)
4.2 All the time setted by the timer passes.
Case 4:
- Electronic control disabled
- Nozzle contact YES
In this case the operating sequence is:
1. The operator takes the nozzle and the pump starts up.
2. The refuelling is done
3. The pump cuts out because of one of the following cases:
3.1 The operator replaces the nozzle.
The listed cases are valid with tank in normal condition and no in reserve condition, that is with absent Low Level Contact.
If the Low Level Contact intervenes, the dispensing is immediately stopped, even during the refuelling.
In these condition, dispensing is allowed only by the following procedure:
Forced Dispensing with Low Level Contact on
When the Low Level Contact intervenes, the system allows dispensing ONLY with a forced procedure.
The Start button must be pressed for 5 seconds. The Key led starts flashing _ _ _ _ _ _ _ _ _
In this way the pump block is inhibited for a single dispensing.
The next steps to dispense depend on the configuration of the system (as the previous paragraph describes).

TROUBLESHOOTING
PROBLEM POSSIBLE CAUSES SOLUTIONS
The Power Led does not light up - The system is not correctly power
supplied
- Power connections are not correct
- Verify the voltage electricity
network
- Verify power connections
The motor does not start up - The electrical connections are not
correct
- The DIP switch settings are not
consistent with the expected
functions.
- The motor fuse has blown
- Verify electrical connections
- Verify the DIP switch
- Verify the motor fuse on the
electronic board.
The motor starts up before receiving
the consent from the nozzle contact,
even if the DIP switch is correctly
configured
- When the system was powered the
first time, the nozzle was held up
and the nozzle contact was closed.
- ATTENTION: If the nozzle contact
has been configured, when the
system is powered the nozzle must
be replaced in its housing (open
contact). This is requested because
the system verifies all the
peripherals at the start up.
- Switch off the system, placed the
nozzle in its housing and switch on
the system again.
The system has an anomalous
behaviour or it never gives the
consent for starting up the motor
- Low tank level – Level sensor
enabled
- Software configurations are not
correct
- Problems of the board
- Verify the level and that the level
sensor works well
- Verify the software configurations.
Verify the number and the type of
the requested consents for
dispensing
- Verify that all the electrical
connections that concern the
consents are correct.
- If everything is correct, but the
system continues not working well
and it is necessary dispening only
by mean of the nozzle contact, set
the DIP switch 3 to bypass all the
electrical consents except the
nozzle contact.
Follow the instructions:
- Switch off the system
- Open the box taking off the screws
to get access to the board
compartement.
- Put the DIP switch 3 in “Electronic
control disabled”
