Dx34510b_oi_e.doc / Jun-15 Page 7 / 42
When using this earthing option, please observe:
All terminals and potentials marked “GND“ will be earthed.
You should avoid multiple earthing, e.g. when you use a DC power supply where the
Minus is already connected to earth etc. Especially under poor earthing and grounding
conditions, multiple earth connections may cause serious EMC problems.
Independent of your setting, all functions of the unit are “active HIGH“ and the unit
triggers to positive transitions (rising edge).
With NPN setting please be aware that an open or unused RESET input is HIGH.
Therefore the unit will be kept in a continuous RESET state and will not work, unless you
tie the Reset line to GND (terminal 1 or 6)
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.
2.1. Power Supply
The unit accepts DC supply from 17 V to 30 V when using terminals 1 and 2, and the consumption
depends on the level of the supply voltage (typically between 80 mA and 150 mA
plus current taken from aux. output).
For AC supply, terminals 0 VAC, 115 VAC or 230 VAC can be used. The total AC power
consumption is 7.5 VA.
Units with option "SV006" are prepared for AC supply with 24 VAC or 42 VAC and the screw
terminals are marked correspondingly.
The diagrams show a dotted line for grounding to PE. This connection is not necessary, neither for
safety nor for EMC. However, with specific applications, it can be useful to ground the common
potential of all signal lines.
2.2. Aux. Voltage Output
Terminal 7 provides an auxiliary output of 24 VDC / 120 mA max. for supply of sensors and
encoders. Units with TTL inputs (option TTLIN1) provide a 5 VDC / 120 mA auxiliary output on
terminal 7 instead.
2.3. Inputs A, B and Reset
In the basic setup menu these inputs can be configured to PNP (switch to +) or
to NPN (switch to -). This configuration is valid for all three inputs at a time.
The factory setting is always PNP.
With standard units the input level is always HTL (Low <2.0 V and High >9.0 V)
Units equipped with option TTLIN1 provide TTL / CMOS) level (Low <0.8 V and High >3.5 V)

The counting inputs A and B are designed for input frequencies up to 100 kHz (with all counter
modes) and up to 25 kHz (with all other operating modes). The minimum pulse duration on the
Reset input must be 500 µsec. (maximum frequency 1 kHz). All inputs are designed to receive
impulses from an electronic impulse source. Where exceptionally you need to use mechanical
contacts, please connect an external capacitor between GND (-) and the corresponding input (+).
With a capacity of 10 µF, the maximum input frequency will reduce to 20 Hz and miscounting due
to contact bouncing will be eliminated.
2.4. Adjustable Analog Output (DX 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 signal polarity changes with the sign in the display.
The outputs provide a 14 bits resolution and the response time to changes of the measuring value
is approx. 7 msec. (fin > 143 Hz). The maximum current of the voltage output is 2 mA, and the load
on the current output can vary between 0 and max. 270 ohms.
2.5. Optocoupler / Transistor Outputs (DX 347 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....30V). 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.
*) For relay outputs please refer to model DX342

3. How to Operate the Front Keys
For setup and other operations the unit uses three front keys which subsequently will be
denominated as follows:
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
3.1. Normal Display State
The Cmd key is only used to execute the Teach procedure with linearization. For more details
please refer to sections 5.1 and 5.2.
Dx34510b_oi_e.doc / Jun-15 Page 11 / 42
3.2. Selection and Setting of Parameters
3.2.3. 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.
3.2.4. 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)
3.2.5. 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.
3.2.6. 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, all changes which have not been confirmed by
ENTER yet would remain unconsidered.
Dx34510b_oi_e.doc / Jun-15 Page 12 / 42
The Time-Out Function remains disabled 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.
This action will reset all parameters to factory default values and your own
settings will be lost. You will have to repeat your individual setup procedure.
Factory default values are shown in the subsequent parameter tables.
3.3. Teach Operation
For details of the Teach procedure see section 5.2.
3.4. Set All Registers to “Default“
At any time you can return all settings to the factory default values.
To reset the unit to default values:
switch power off
press the ENTER key on the front
keep ENTER down while you power up again
3.5. 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.
