7 Trouble shooting What to do, if…?

…the LC display is too pale or dark?

 The contrast setting is incorrect. It should be adjusted (chapter 5.3.4.3.2) If the

display is no longer legible, the contrast setting can be reset to the factory set-

ting (44) by pressing the 'EXIT' button when switching the HDA eco on. The but-

ton must stay pressed until the date and time are displayed.

…the language has been accidentally changed?

 The language can be set 'blindly'. For this, change to the management mode

(chapter 5.3) and using the ‚▼ button, change downwards three menu points

following this, confirm with the 'ENTER' button, change downwards two menu

points, then change downwards two menu points once again and confirm. The

correct language can now be selected using the◄ and ‚► buttons and then con-

firmed with 'ENTER'.

…after drawing the nozzle and/or starting the delivery of fuel, the pump is not

switched on via the keyboard?

 The pump motor is not correctly connected to the switch output of the HDA

eco. Check the connection. If an additional relay or safety device is used, check

the connection of this component.

 The setting of the menu point 'nozzle switch y/n' (chapter 5.3.4.1.5) is not cor-

rect. Adjust the setting.

 HDA eco is blocked. Unblocking should take place in the corresponding menu

(chapter 5.3.4.2.4).

 HDA eco is blocked due to too many zero fillings. It should be unblocked (chap-

ter 5.3.4.2.4) and the reason for the zero fillings should be dealt with, e.g. a de-

fective pump, or a defective flow meter. As the case may be, the number of

successive zero fillings should be increased (chapter 5.3.4.2.6.)

…the pump runs and the medium is pumped, but the quantity display does not

change?

 The flow meter is not correctly connected to the pulse input of the HDA eco.

The connection should be checked (chapter 2.5.1, chapter 3.1).

 The flow meter is blocked. It should be checked and, as the case may be,

cleaned.

…the pump runs and the medium is pumped, but the quantity display does not corre-

spond with the quantity which is dispensed?

 The pulse value in the HDA eco does not correspond with that of the flow me-

ter. It should be checked and adjusted (chapter 5.3.4.2.2) As the case may be, a

calibration should be carried out (chapter 3.2).
