1.1. Power Supply
The unit accepts DC supply from 17 V to 30 V when using terminals 1 and 2. The consumption
depends on the level of the supply voltage
(typical 130mA at 30V or 190mA at 17V, plus current taken from aux. output).
For AC supply the terminals 0 VAC, 115 VAC or 230 VAC can be used.
The total AC power is 7.5 VA.
The diagrams below show a dotted line for grounding to PE.
This connection is not really necessary, neither for safety nor for EMC. However, for some
applications, it may be desirable to ground the common potential of all signal lines.
When using this earthing option, please observe:
•All terminals and potentials marked “GND“ will be earthed.
•Please avoid multiple earthing, i.e. when you use a DC power supply where
the Minus is already connected to earth etc.
1.2. Aux. Voltage Output
Terminal 7 provides an auxiliary output of 24 VDC / 120 mA max. for supply of sensors and
encoders.
1.3. Control Inputs A, B and C
With models IX 348, input A is used to activate a serial transmission (rising edge, see 4.5.2).
Input B is not in use.
Input C operates as a Set / Reset input (static function, active "HIGH", see 5.3).
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.
•Where NPN setting is used, please observe:
Open NPN inputs will always represent a logical HIGH state
Consequently, Input C has to be connected to GND externally to allow normal
operation. If unconnected, the unit would be kept in a continuous Reset state.
With models IX 348, also Input A must be tied to GND, and opening this connection will
generate a rising edge to start a serial transmission
•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.
1.4. Adjustable Analogue Output (IX 346 only)
A voltage output is available, operating in a range of 0 ... +10 V or –10 V ... +10 V according to
setting. At the same time, a current output 0/4 – 20 mA is available. Both outputs refer to the
GND potential and the polarity changes with the sign in the display. The outputs are
proportional to the display value and provide a 14 bits resolution.
The maximum current on the voltage output is 2 mA, and the load on the current output can
vary between 0 and max. 300 ohms.
The response time of the analogue output to changes of the encoder position is approx. 7 msec.
1.5. Optocoupler (transistor) outputs (IX 437 only)
The outputs provide programmable switching characteristics and are potential-free. Please
connect terminal 8 (COM+) to the positive potential of the voltage you like to switch
(range 5V....35V). You must not exceed the maximum output current of 150 mA. Where you
switch inductive loads, please provide filtering of the coil by means of an external diode.
The optocoupler outputs provide a response time of approx. 5 msec with resistive load.

1.6. Serial RS232 / RS485 interface (IX 348 only)
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.

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:
•Normal display state
•Setup state
a.) Basic setup
b.) Operational parameter setup
•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 ENTER and SET down simultaneously for 3 seconds
Operational
parameter setup
Keep ENTER down for 3 seconds.
Teach operation Keep Cmd 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.

IX34510a_e.doc / Apr-11 Page 9 / 43
2.2. Selection and Setting of Parameters
2.2.1. How to select a parameter
The ENTER key will scroll through the menu. The SET 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 SET key
continuously down, the highlighted digit will scroll in a continuous loop from 0 … 9 , 0 … 9.
After releasing the SET 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 ENTER 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 ENTER 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 ENTER yet would remain unconsidered.

IX34510a_e.doc / Apr-11 Page 10 / 43
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:
•Power the unit down.
•Press the ENTER key.
•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.

IX34510a_e.doc / Apr-11 Page 11 / 43
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 set-
up, 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.

4.3. Additional Parameters for the Analogue Output
(model IX 346)
The following additional settings for the analogue output appear in the Basic Menu:
Menu Setting Range Default
Analogue Characteristics
You can set the following output options:
+/- 10 V (bipolar),
0 - 10 V (positive only),
4 - 20 mA
0 - 20 mA.
With setting +/-10 Volts the polarity of the output
voltage will follow the sign in the display
Analogue Offset:
Set this parameter to 0 when you expect your
analogue signal to start with 0 V (or 0 mA / 4 mA
respectively). Where another zero definition is
desired it can be set by this parameter. Setting of
e.g. 5.000 will already produce 5 volts with the
output in zero state.
-9,999..+9,999 0,000
Analogue Gain:
Parameter to set the analogue output swing. Setting
10.00 will allow full swing of 10 V or 20 mA, setting
8.00 will reduce the swing to 8 V or 16 mA.
00,00..99,99 10,00
The following Operational Parameters provide scaling of the analogue output:
Menu Setting Range Default
Analogue-Begin
Start value of the analogue conversion range
-199999...999999 0
Analogue-End
End value of the analogue conversion range
-199999...999999 100000
By means of these two parameters any window of the whole display range can be mapped onto
the analogue output.

IX34510a_e.doc / Apr-11 Page 19 / 43
