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 such as relays, motors,
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 to make reference at 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. 90 x 66
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),
absolute/relative display mode and mm/Inch display
mode, 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

In order to activate modified parameters, switch off
and on the device.

Level 1: Func1
P00 Datum value / Eich [-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]
Enter the number of pulses 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 200
