7.10 Factory Settings
By recalling the factory settings (implemented by the manufacturer), you return to a predefined
starting position. This is useful to start the input of a new parameter set.
These are the values contained in the factory settings:
RI = 0.50 ms, FA = 0.50 ms, OT = 2.0 ms, NL = 70 %, DL = 10.0 ms and NP = 1.
– Step 1: Press [recall].
– Step 2: [↓] immediately opens this parameter set.
– Step 3: Confirm the selection with [enter].
INFORMATION
Aborting the process
The working configuration (setup 0) is changed to the factory settings. Press [esc] to abort at any
time.

With Setup ALL (see paragraph 4.5.6 "Submenu “Service-Option”", page 33) Setup 4 – 10 get the
same values as setup 0 (working configuration).
The factory settings for all four scenarios are the same. The PLCStop is “OFF”, the other

7.11 First Drop
The first drop mode is especially useful, if you want to work parallel with several systems. With
the help of first drop you can make sure all values and parameters are comparable. With the first
drop adjust you find the exact position, where the tappet does not completely close the nozzle
and where you can see the “first drop”. This position depends mainly on the properties of the
medium you want to dispense, especially its viscosity.
You can only use the first drop mode, if in the submenu “Status” the function “FirstDrop” is set to
“ON” (see paragraph 4.5.4 "Submenu “Status”", page 31). If this is the case, the red first drop LED
will be ON, until a successful first drop adjust has been completed.
Before the first drop adjust a normal adjust has to be performed.
IMPORTANT NOTE
Cancelling the first drop adjust
You can cancel the first drop adjust at any time by pressing the [esc]-key.
It is possible to alternatively perform the first drop adjust remotely via the serial interface (see
paragraph 8.2.4, page 126).
Picture Explanation
Before you can start the first drop adjust, you have to switch “FirstDrop” to
“ON” in the MDC submenu “Status”. The red LED “function” is now on.
The current value of the Needle Lift is taken for the True Needle Lift (TNL). If
the value of the Needle Lift is higher than 70 %, the TNL will be set to 70 %.
You start the first drop adjust by pressing [F2] on the keypad of the control
unit.
The message “Fill up with Medium!!!!!” appears in the display.
