1.1. Power Supply
The unit accepts DC supply from 17 to 30 VDC which must be applied to terminals 1 and 2.
The current consumption depends on the level of the supply voltage and is typically 130mA at
30V or 190mA at 17V, plus currents taken from aux. output).
1.2. Aux. Voltage Output
Terminal 7 provides an auxiliary output of 24 VDC / 120 mA (+/-15%) for supply of sensors and
encoders.
1.3. Control Inputs A, B and Reset ( C )
Standard units use only input “C” as a Reset input and the other inputs are out of function.
In the basic setup menu the inputs can be configured to PNP (signal must switch to +) or to NPN
(signal must switch to -). This configuration is valid for all three inputs at a time.
The factory setting is always PNP.
x Independent of your setting, all functions of the unit are “active HIGH“ and
the unit triggers to positive transitions (rising edge). Because with NPN
setting open or unused inputs are HIGH, you must tie the Reset line to GND
for operation. Otherwise your unit will be in a continuous RESET state and
cannot work.
x Where your
use 2-wire NAMUR type sensors, please select NPN, connect
the negative wire of the sensor to GND and the positive wire to the
corresponding input.

The minimum pulse duration on the Reset input (C) must be 5 msec.
IX34208a_e.doc / Aug-09 Page 6 / 40
1.4. Relay Outputs
The unit provides two presets with relay outputs (dry change-over), each with a switching
capability of 250 VAC / 1A / 250 VA or 100 VDC / 1A / 100 W respectively.
The response time of the relays is approx. 10 msec.
In case of switching inductive loads it is advisable to use external filtering of the coils.
1.5. Serial RS232 / RS485 interface
Ex factory the unit is set to RS232 communication. This setting can be changed to RS485
(2-wire) by means of an internal DIL switch. To access the DIL switch, you must remove the
screw terminal connectors and the backplane. Then pull the board to the rear to remove the
PCB from the housing.

x Never set DIL switch positions 1 and 2 or DIL switch positions 3 and 4 to
“ON” at the same time!
x After setting the switch, shift the print carefully back to the housing and
avoid damage of the front pins
for connection to the front keypad plate.
IX34208a_e.doc / Aug-09 Page 7 / 40
2. How to Operate the Front Keys
For setup and other operations the unit uses three front keys which subsequently will be
denominated as follows:
«
ENTER
(Input)
SET
(Setting)
Cmd
(Command)
The functions of the keys are depending on the actual operating state of the unit.
The following three operating states apply:
x Normal display state
x Setup state
a.) Basic setup
b.) Operational parameter setup
x Teach operation
2.1. Normal display state
You can only change over to other operation states while the unit is in the
normal display state.
Change over to Key operation
Basic setup Keep EENTER and SSET down simultaneously for 3 seconds
Operational
parameter setup
Keep EENTER down for 3 seconds.
Teach operation Keep CCmd down for 3 seconds
The Cmd key is only used to execute the Teach procedure with linearization. For more details
please refer to sections 6.1 and 6.2.
IX34208a_e.doc / Aug-09 Page 8 / 40
2.2. Selection and Setting of Parameters
2.2.1. How to select a parameter
The EENTER key will scroll through the menu. The SSET key allows to select the corresponding
item and to change the setting or the numeric value. After this, the selection can be stored by
ENTER again, which automatically changes over to the next menu item.
2.2.2.
How to change parameter settings
With numerical entries, at first the lowest digit will blink. When keeping the SSET key
continuously down, the highlighted digit will scroll in a continuous loop from 0 … 9 , 0 … 9.
After releasing the SSET key, the actual value will remain and the next digit will be highlighted
(blink). This procedure allows setting of all digits to the desired values. After the most
significant digit has been set, the low order digit will blink again and you can do corrections if
necessary.
With signed parameters, the high order digit will scroll from “0” to "9" (positive) followed by
“-“ and "-1" (negative)
2.2.3.
How to store settings
To store the actual setting, press the EENTER key, which will also automatically scroll forward
the menu.
At any time the unit changes from programming mode to normal display operation, when you
keep the EENTER key down again for at least 3 seconds.
2.2.4.
Time-out function
A “time-out” function will automatically conclude every menu level, when for a break period of
10 seconds no key has been touched. In this case, any changes which have not been confirmed
by EENTER yet would remain unconsidered.
IX34208a_e.doc / Aug-09 Page 9 / 40
2.3. Teach operation
The Time-out function will be switched off during all Teach operations
Key Function
«
ENTER will conclude or abort any Teach operation in progress
SET function is fully similar to normal set-up operation
Cmd will store the display value to the register and will change over to the
next interpolation point.
For details of the Teach procedure see section 6.2.
2.4. Set all parameters to “Default“
At any time you can return all settings to the factory default values.
The factory default settings are shown in the parameter listings in section 6.
When you decide to set all parameters to „default“, please be aware that all
previous settings will be lost and you will need to do the whole set-up
procedure once more
To execute the „Default“ setting function:
x Power the unit down.
x Press the ENTER key.
x Power the unit up again while the ENTER key is kept down
2.5. Code Locking of the Keypad
When the code locking of the keypad has been switched on, any key access first results in
display of
To access the menu you must press the key sequence
«
«
«
within 10 seconds, otherwise the unit will automatically return to the normal display mode.
IX34208a_e.doc / Aug-09 Page 10 / 40
3. The Operator Menu
The menu provides one section with “Basic Parameters” and another section with “Operational
Parameters”. On the display you will only find those parameters which have been enabled by
the basic settings. E.g. when the Linearisation Functions have been disabled in the basic setup, the associated linearization parameters will also not appear in the parameter menu.
All parameters, as good as possible, are designated by text fragments. Even though the
possibilities of forming texts are very limited with a 7-segment display, this method has proved
to be most suitable for simplification of the programming procedure.
The subsequent table shows the general structure of the whole menu only.
Detailed descriptions of all parameters will follow in section 4.

4. Setup Procedure
For better understanding the following sections 4.1 and 4.2 explain settings for the display only.
Settings for Preselections and Serial Link will be explained separately, later.
4.1. Basic Parameters
The subsequent settings are of unique nature and must only be made upon the very first setup.
