compression chamber (the cavity at the rear end of the nozzle insert). The
interval is adjustable in steps of 0.01 ms.
Delay (DL)
This waiting phase between two cycles is adjustable in steps of 0.1 ms, but it
is recommended to use at least 0.2 ms.
Needle Lift (NL)
This parameter describes the stroke of the tappet, compared to its full value
of 100 %. For the range between 81 % and 100 %, the valve works in bipolar
mode. The elevated temperature in this range reduces the average frequency
and the lifetime of the valve. A needle lift between 70 % and 80 % is the best
working range.

7.5 Input of Values
Modification of parameter values is simple. The name of the parameter appears in the upper, the
assigned numerical value in the lower line of the screen. If the last digit before the decimal point
is flashing, you can modify the value.
• Increase by one by using the [↑]-key.
• Correspondingly, the [↓]-key reduces the value by one.
• The [→]-key shifts the position of the active digit to the right.
• To shift the active position to the left, use the [←]-key.
Selection of other values (no numerical values) is performed similarly.
• Use the [→]-key or the [←]-key to change between ON and OFF.
• An input must be confirmed by [enter], to save the current selection. Then the control returns
to the next-higher menu point.
• To cancel without saving the current selection, press [esc]. The screen returns to the next-
higher menu level.
INFORMATION
Changing numbers
When modifying the first digit of a value from “1” to “0”, the cursor automatically jumps one
position to the right (if possible). The value in this position is set to 5, but you can modify it.
7.6 Saving Parameter Sets
Ten storage locations are available to save the pulse parameters from the menu.
– Step 1: Open the storage menu by pressing [save].
– Step 2: Select the desired storage location with the arrow keys.
– Step 3: Confirm the selection by pressing [enter].
INFORMATION
[esc] to abort
Pressing [esc] causes the saving procedure to be aborted. You can also use the submenu “Pulse
Parameters” (see paragraph 4.5.2, page 29) to save parameters.
7.7 Retrieving Parameter Sets
Parameter combinations saved in the system can be recalled any time.
– Step 1: Press [recall] to activate the corresponding function.
– Step 2: Select the desired storage location with the arrow keys.
– Step 3: Confirm the selection by pressing [enter].
INFORMATION
[esc] for interrupt
[esc] interrupts the procedure at once.
