The device has a green LED on its front foil. This lights up permanently as soon as the supply voltage
of the device has been applied. If an error occurs, the LED flashes at 1 Hz.
The analog output is also controlled with 0 V or 0/4 mA. If the error no longer exists, the LED
automatically lights up again permanently and the analogue output responds to the current result.
The exact error can be read out via the serial interface via the user interface (OS).
( Variable: Error_Status, Code: "; 3")
The individual error codes are explained below:
9085_5010_04a_oi_e.docx / Feb-21 page 10 / 72
Electrical Connections
The terminal screws should be tightened with a slotted screwdriver (blade width 2mm).
DC Power Supply (X1)
The unit accepts DC supply from 18 to 30 V at the terminals X1 1 and 2. The power consumption
depends on the level of the supply voltage with aprox. 50 mA and the additional current required at
the Auxiliary Voltage Output.
All GND terminals are internally interconnected.
Auxiliary voltage output (X2)
Two auxiliary voltages (24 VDC and 5 VDC) are available as encoder / sensor supply at terminal X2
pins 7, 8 and 9. The 24 VDC output voltage depends on the device supply (see technical data).
9085_5010_04a_oi_e.docx / Feb-21 page 11 / 72
Incremental encoder input (X2)
RS422
HTL DIFFERENTIAL
HTL PNP
HTL NPN
Terminal X2 pins 3, 4, 5 and 6 provide a connection for various incremental signals.
9085_5010_04a_oi_e.docx / Feb-21 page 12 / 72
Continuation „Incremental encoder input (X2)“:
HTL NPN (NAMUR)
TTL (PNP)
Unconnected PNP inputs are always “LOW” and unconnected NPN inputs are always “HIGH”.
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.
9085_5010_04a_oi_e.docx / Feb-21 page 13 / 72
SSI-Absolute encoder input (X2)
At terminal X2 pin 1, 2, 3, 4 the SSI connection for the MODE MASTER is available.
At terminal X2 pin 3, 4, 5, 6 the SSI connection for the MODE SLAVE is available.

9085_5010_04a_oi_e.docx / Feb-21 page 15 / 72
Start-stop encoder inputs (X2)
At terminal X2 - Pin 1+2 the RS422 connection for the init pulse in "MODE MASTER" is available.
(Device generates Init pulse itself!).
At terminal X2 - Pin 5+6 the RS422 connection for the init pulse in "MODE SLAVE" is available. (Init
pulse is generated by an external device!).
At terminal X2 - Pin 3 + 4 the RS422 connection for the Sart-Stop pulse is available.
Connection of the RS422 signals:
DPI measurement operation
In the "MODE MASTER", the init pulse is sent to the position sensor on the init line at regular
intervals (SAMPLING TIME (ms)), whose rising edge triggers a measurement.
The pulse width of the init pulse can be set by means of the "INIT PULSE TIME (µs)" parameter.
T
: 1…9 µs (adjustable)

Note: With an HTL pulse (rising edge) on Ctrl. In 6, the device is reset to the factory
settings.
Control Inputs (X5)
At terminal X5 pins 2,3,4,5,6 and 7 there are six control inputs with HTL PNP characteristic available.
Control Input 1 (Ctrl. In 1) to Control Input 5 (Ctrl. In 5) are freely configurable in the COMMAND
MENU and are used for functions to be triggered externally. eg. for releasing the latching, resetting
the measurement result or for teaching the preset values or the analog output.
Control input 6 (Ctrl. In 6) is used exclusively for resetting the device parameters to the "default"
values. Thus, it is not freely configurable.
Wiring of the control inputs:
Unconnected control inputs are always “LOW”.
All inputs are designed to receive impulses from an electronic impulse source.
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.
9085_5010_04a_oi_e.docx / Feb-21 page 17 / 72
Analog output (X4)
Important:
A parallel operation with voltage and current output at the analog output is not allowed.
A 16 bit analog output is available at terminal X4 pin 1, 2 and 3.
This output can be configured and scaled in the ANALOG MENU.
The following configuration is possible:
• Voltage output: -10 … +10 V
• Current output: 0 … 20 mA
• Current output: 4 … 20 mA
The analog output is proportional to the display value and is referenced to potential AGND.
AGND and GND are internally interconnected.
9085_5010_04a_oi_e.docx / Feb-21 page 18 / 72
Serial interface (X3)
Important: Parallel operation of RS232 and RS485 is not allowed!
The serial USB communication is done with a baud rate of "
115200 Baud
" and a serial data
format of "
