IMPORTANT NOTE
Minimum values for Fixed Adjust mode and First Drop mode
The minimum values for Falling and Rising in the table are only correct, if the system is not in
fixed adjust mode (see paragraph 7.12, page 76) or first drop mode (see paragraph 7.11,
page 71).
In fixed adjust mode, the minimum values for Falling (0.30 ms) and Rising (0.50 ms) are fixed and
do not depend on the Needle Lift.
In first drop mode, the minimum values for Falling and Rising are determined by the following
formulas:
Min. Falling = (Min. Falling at 100% NL) x (TNL + 30)/100
Min. Rising = (Min. Rising at 100% NL) x (TNL + 30)/100
If this formula results in a value, which cannot be used, it is rounded up to the next possible
value (e.g. 0.201 ms would be rounded to 0.21 ms).

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.

7.8 Select Pins
Setups can be directly controlled via the select pins of the AUX socket (see Fig. 24), if “Scenario”
in the submenu “Scenario” is turned “OFF”. (In case “Scenario” is “ON” and you want to work with
the scenarios, please refer to paragraph 7.9.3, page 67.) The select pins allow you to switch in real
time between the setups 0 to 3.
INFORMATION
Setup 0 = working configuration
Please be aware that setup 0 is the working configuration and therefore is not programmed
additionally.
With the pins Select_I (AUX socket Pin 5) and Select_II (AUX socket Pin 8) it is possible to switch
rapidly between different sets of parameters. In their blank state, the select pins are on a high
level (pull-ups to 24 V). You have to switch them to low (Gnd) to select a different setup (see Fig.
26, page 65 and see Tab. 21, page 65). For additional information regarding the AUX socket, see
paragraph 8.3, page 128. You have to switch them before triggering.
