1. Safety Instructions and Responsibility
1.1. General Safety Instructions
This operation manual is a significant component of the unit and includes important rules and hints about
the installation, function and usage. Non-observance can result in damage and/or impairment of the
functions to the unit or the machine or even in injury to persons using the equipment!
Please read the following instructions carefully before operating the device and observe all safety
and warning instructions! Keep the manual for later use.
A pertinent qualification of the respective staff is a fundamental requirement in order to use these manual.
The unit must be installed, connected and put into operation by a qualified electrician.
Liability exclusion: The manufacturer is not liable for personal injury and/or damage to property and for
consequential damage, due to incorrect handling, installation and operation. Further claims, due to errors in
the operation manual as well as misinterpretations are excluded from liability.
In addition the manufacturer reserves the right to modify the hardware, software or operation manual at any
time and without prior notice. Therefore, there might be minor differences between the unit and the
descriptions in operation manual.
The raiser respectively positioner is exclusively responsible for the safety of the system and equipment
where the unit will be integrated.
During installation or maintenance all general and also all country- and application-specific safety rules and
standards must be observed.
If the device is used in processes, where a failure or faulty operation could damage the system or injure
persons, appropriate precautions to avoid such consequences must be taken.
1.2. Use according to the intended purpose
The unit is intended exclusively for use in industrial machines, constructions and systems. Non-conforming
usage does not correspond to the provisions and lies within the sole responsibility of the user. The
manufacturer is not liable for damages which have arisen through unsuitable and improper use.
Please note that device may only be installed in proper form and used in a technically perfect condition (in
accordance to the Technical Specifications). The device is not suitable for operation in explosion-proof
areas or areas which are excluded by the EN 61010-1 standard.
.

1.3. Installation
The device is only allowed to be installed and operated within the permissible temperature range. Please
ensure an adequate ventilation and avoid all direct contact between the device and hot or aggressive
gases and liquids.
Before installation or maintenance, the unit must be disconnected from all voltage-sources. Further it must
be ensured that no danger can arise by touching the disconnected voltage-sources.
Devices which are supplied by AC-voltages must be connected exclusively by switches, respectively
circuit-breakers with the low voltage network. The switch or circuit-breaker must be placed as near as
possible to the device and further indicated as separator.
Incoming as well as outgoing wires and wires for extra low voltages (ELV) must be separated from
dangerous electrical cables (SELV circuits) by using a double resp. increased isolation.
All selected wires and isolations must be conform to the provided voltage- and temperature-ranges. Further
all country- and application-specific standards, which are relevant for structure, form and quality of the
wires, must be ensured. Indications about the permissible wire cross-sections for wiring are described in
the Technical Specifications.
Before first start-up it must be ensured that all connections and wires are firmly seated and secured in the
screw terminals. All (inclusively unused) terminals must be fastened by turning the relevant screws
clockwise up to the stop.
Overvoltage at the connections must be limited to values in accordance to the overvoltage category II.
For placement, wiring, environmental conditions as well as shielding and earthing/grounding of the
supply lines the general standards of industrial automation industry and the specific shielding
instructions of the manufacturer are valid.
1.4. Cleaning, Maintenance and Service Notes
To clean the front of the unit please use only a slightly damp (not wet!), soft cloth. For the rear no cleaning
is necessary. For an unscheduled, individual cleaning of the rear the maintenance staff or assembler is
self-responsible.
During normal operation no maintenance is necessary. In case of unexpected problems, failures or
malfunctions the device must be shipped for back to the manufacturer for checking, adjustment and
reparation (if necessary). Unauthorized opening and repairing can have negative effects or failures to the
protection-measures of the unit.

2. Introduction
The display device is designed for panel mounting. It is universally applicable, with its intuitive operation
and the extensive features.
2.1. Operation mode
All functions are can be configured in the parameter menu.
The device can be set to one of the following operation modes:
•DISTANCE (Distance measurement)
The scaling (setting of the display unit) is set with the parameter FACTOR and DIVIDER. When
measuring the distance, the default setting (FACTOR = 1, DIVIDER = 1 and DECIMAL POINT = 3)
corresponds to a position display in the unit "mm" in the following display format: "00000.000" mm.
For example, to display a position in "inch" with three decimal places as well, the parameter
FACTOR must be set to 10 and the parameter DIVIDER to 254. The unit "inch", which is to be
displayed in the display, is set in the parameter SCALE UNITS.
•ANGLE (Angle Measurement)
For angle measurement, the default setting (FACTOR = 1, DIVIDER = 1, and DECIMAL POINT = 3)
corresponds to an angle display of 0 –360 degrees with three decimal places.
With the parameter LENGTH PER REVOLUTION, the distance travelled is set per 360 degrees (in
millimeters). With the parameters FACTOR and DIVIDER, the display can be scaled again if
necessary. (for example, to hide decimal places). The unit “degree” can be set in the SCALE UNITS
parameter.

3. Electrical Connections
The terminal screws should be tightened with a slotted screwdriver (blade width 2mm).
3.1. DC Power Supply
The unit accepts DC supply from 18 to 30 V at the terminals 1 and 2. The power consumption depends on
the level of the supply voltage with approx. 100 mA and the additional current required at the Auxiliary
Voltage Output.
All GND terminals are internally interconnected.
3.2. Auxiliary Voltage Output
Terminal 3 and 4 provide an auxiliary output for supply of sensors and encoders.
The output voltage depends on the power supply.
The encoder voltage is approx. 1 V lower than the power supply voltage at terminal 1 and 2 and should be
loaded with max. 250 mA.
The auxiliary voltages output is switchable from 24 VDC to 5 VDC.
8
3.3. RS-485 inputs and outputs
At Terminal 5, 6, 7 and 8, the connection is available for the RS485 signals (Init + Sart-Stop impulse).
Wiring for RS485 signals:
DPI-Measurement mode:
On the Init line, the Init impulse is sent to position encoder at regular intervals, whose rising flank triggers a
measurement.
TInit : 1…5 µs
TStart: 3…5 µs
TStop: 3…5 µs

3.4. Control Inputs
The three control inputs at terminal 10, 11 and 12 have HTL PNP characteristics.
In the COMMAND MENU the programmable functions for the control inputs can be assigned. Available
functions are: display switching, locking the touch screen or release the lock function of the control or relay
outputs.
Wiring of the control inputs:
Unconnected PNP inputs are always “LOW.
All inputs are designed to receive impulses from electrical impulse sources.
Notice for mechanical switching contacts:
When exceptionally mechanical contacts are used, please connect an external capacitor between GND (-)
and the corresponding input (+). A capacity of 10 µF will reduce the input frequency to
20 Hz and miscounting due to contact bouncing will be eliminated.
3.5. Relay-Output
Two relay outputs with potential-free changeover contacts are available at terminal 27, 28, 28, 30, 31 and
32. Switching conditions can be set in the PRESELECTION MENU. The switching states are displayed
(display with unit and status bar) as K1 and K4.
AC-switching capacity max 250 VAC/ max 3 A / 750 VA
DC-switching capacity max 150 VAC/ max 2 A / 50 W
