1 Safety summary
For the electrical connections, we recommend to
closely follow these electrical instructions. In
particular, according to the 89/336/EEC norm on
electromagnetic compatibility, following
precautions must be taken:
• Measurement system (sensor) should be
installed as close as possible to the display.
• Always use shielded and twisted cables if
possible.
• Avoid running the sensor cable near high
voltage power cables (e.g. drive cables).
• Install EMC filters on sensor power supply if
needed.
• Avoid mounting sensor near capacitive or
inductive noise sources and switching power
supplies.
• static discharge can damage internal sensitive
electronic components. Before handling and
installing, discharge electrical
charge from your body and tools
which may come in touch with
the device.
Connect according to the chapter 5: “Electrical
connections”.
2 Identification
The device can be identified by the label's data
(ordering code, serial number). This information is
listed in the delivery document. For technical
features of the product, refer to the technical
catalogue.
3 Installation
Install the device according to the protection level
provided. Protect the system against knocks,
friction, solvents and respect the environmental
characteristics of the product.
4 Mounting recommendations
Push the display into the cut&out (approx. 92 x 68
mm2) without panel clips.
Install panel clips on the display's housing and
screw until fixed.

6 Functions
6.1 Start up
At start up the unit shows the software version
followed by actual position.
Software version: SOF xx
6.2 Key functions
Key Function
F Function (save + exit setup)
Shift Right (select parameter / digit)
Up (change value)
E Enter (save + scroll menu)
6.2.1 Default parameter (factory settings)
Default parameter values are written in BOLD
characters. The unit can be reset to default values
by pushing F, and E key while switching on.
6.2.2 Direct functions
To set direct functions, such as reset, reset with
datum value, tool correction (offset value), program
P07 parameter.
7 Set up
7.1 Access to setup menus
Push F key to enter setup.
• push to select Func 1 or Func 2
• push E to scroll parameters
• push F to exit setup
Admissible value range for each parameter is listed
as follows: [min. value, max. value]
7.2 Parameter setting
Level 1: Func1
Eich Datum value / Preset [&99999, 999999]
Display can be set to datum value (or preset) by
activating SET input or pushing key.
Default value: 50.0
Level 2 : Func2
P00 Display value per distance moved [1, 10000]
Enter the value to be displayed when the unit
receives the number of pulses per distance moved
in parameter P01. Note this value is entered
without decimal.
Default value: 100
P01 Nr. of pulses per distance moved [1, 65000]
The display is always set on 4 edge counting mode.
Enter the number of encoder pulses x4 per
distance. This same distance unit is used to
determine the Display value per distance moved.
Default value: 100

Example:
A ball screw moves 12.3mm per revolution. The
system uses a rotary encoder with 200 PPR (pulses
per revolution).
In this case:
P00 should be set to 123 (value without decimals)
P01 is 800
P02 Input / Output pin [0, 1]
Sets pins 7 and 8 as input or output.
0 = Input
1 = Output (optional, see order code)
P03 Counting direction [0, 1]
Sets counting direction of display.
0 = standard counting direction
1 = inverted counting direction
P04 Decimal point [1, 4]
Modification of decimal point position. This setting
has no influence on other parameters.
0 = 000000
1 = 00000.0
….
4 = 00.0000
P05 Password Level 1 [0, 999999]
Enter desired code number here to prevent
operator from entering the "Datum value mode"
(Level 1).
Default value: 0
Attention: Datum value can be set only after
digiting the correct password.
To cancel password and restore default value see
chapter “Default parameter” (6.2.1).
P06 Password Level 2 [0, 999999]
Enter desired code number here to prevent
operator from entering the "Parameter mode"
(Level 2).
Default value: 0
Attention: Datum value can be set only after
digiting the correct password.
To cancel password and restore default value see
chapter “Default parameter” (6.2.1).
P07 Function of the push buttons [0, 6]
The function of the and the E button in
operating mode can be selected.
0 = no functions
1 = E will set actual value to zero
2 = will set actual value to Datum/Preset (Func1)
3 = both functions 1 + 2
4 = E activates "Saw blade offset" (P12)
6 = both functions 2 + 4
P08 Reset function [0, 1]
Sets function of Reset input (active if P11 = 0).
