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.

Connection of the 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.

Never set DIL switch positions 1 and 2 or DIL switch positions 3 and 4 to
“ON” at the same time!
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.

For setup and other operations the unit uses three front keys which subsequently will be denominated as follows:
(Input)
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
(Setting)
(Command)

2.1. Normal display state

You can only change over to other operation states while the unit is in the normal display state.
parameter setup
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.

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.

2.3. Teach operation

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.

3. The Operator Menu

IX 345
IX 346
IX 347
IX 348
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.
