4.1 Power supply
The unit accepts DC power supply from 1 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 .5 VA.
Units with option LD30x-P4-... are designed for either 24 VAC or 42 VAC power
supply and the screw terminals are marked correspondingly.
The pictures in the previous page 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.
NOT
When using this earthing option, please note that:
1. all terminals and potentials marked “GND“ will be earthed;
2. 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.
4.2 Aux. voltage output
Terminal provides a 24 VDC / 120 mA max. auxiliary output for supply of
sensors and encoders. Units with TTL inputs (option -M8-) provide a 5 VDC / 120
mA auxiliary output on terminal instead.
4.3 Inputs A, B and Reset
In the basic set-up menu (see section “ .1 Basic settings” on page 14) 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 -M8- provide TTL / CMOS) level (Low <0.8 V and
High >3.5 V).
NOT
1. Independently of your setting, all functions of the unit are “active HIGH“
and the unit triggers to positive transitions (rising edge).
2. 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).
3. When you 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 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.
Should you exceptionally 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.
4.4 Adjustable analogue output (LD301 model 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-bit resolution
and the response time at each change of the measuring value is approx. 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. 2 0 ohms.
4.5 Optocoupler / transistor outputs (LD302 model only) *
Outputs provide programmable switching characteristics and are potential-free.
Please connect terminal 8 (COM+) to the positive potential of the voltage you
want to switch (range 5V ... 30V). You must not exceed the maximum output
current of 150 mA. If you switch inductive loads, please provide filtering of the
coil by means of an external diode.

5 Operating the front keys
For set-up and other operations the unit is fitted with three front keys which
will be denominated as follows in the next pages:
NT R
(Input)
S T
(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 (see section “5.1 Normal display state” on page 8)
•Set-up state (see section “5.2 Selection and setting of parameters” on
page 9)
- Basic set-up (see section “ .1 Basic settings” on page 14)
- Operational parameters set-up (see section “ .2 Operational
parameters” on page 16)
•Teach operation (see section “5.3 Teach operation” on page 10)
5.1 Normal display state
NOT
You can only change over to other operation states while the unit is in display
state.
Change over to Key operation
Basic set-up Keep NT R and S T down simultaneously for 3 seconds
Operational
parameter set-up Keep NT R down for 3 seconds
Teach operation Keep CMD down for 3 seconds
The CMD key is only used to execute the Teach procedure with linearisation. For
more details please refer to sections “8.1 Linearisation“ and “8.2 Manual input or
„teaching“ of the interpolation points” on page 30.

LD30x
5.2 Selection and setting of parameters
5.2.1 Selecting a parameter
The NT R key will scroll through the menu. The S T key allows to select the
corresponding item and change the setting or the numeric value. After this, the
selection can be saved by pressing the NT R key again, which automatically
changes over to the next menu item.
5.2.2 Changing parameter settings
With numerical entries, at first the lowest digit will blink. When keeping the S T
key continuously down, the highlighted digit will scroll in a continuous loop
from 0 to 9 and again from 0 to 9; and so on. After releasing the S T key, the
actual value will remain and the next digit will be highlighted (blink). This
procedure allows setting all digits to the desired values. After the most
significant digit has been set, the low order digit will blink again and you can
make corrections if necessary.
With signed parameters, the high order digit will scroll from “0” to "9" (positive)
followed by “-“ and "-1" (negative).
5.2.3 Saving settings
To save the actual setting, press the NT R key, which will also automatically
scroll forward the menu.
NOT
At any time the unit changes from programming mode to normal display
operation, when you keep the NT R key down again for 3 seconds at least.
5.2.4 Time-out function
A “time-out” function will automatically terminate every menu level, when for a
break period of 10 seconds no key has been pressed. In this case, all changes
which have not been confirmed by NT R yet would remain unconsidered.

LD30x
5.3 Teach operation
NOT
The time-out function remains disabled during all Teach operations.
Key Function
NT R key will terminate or abort any Teach operation in
progress
S T function is fully similar to normal set-up operation
CMD key will save the display value in the register and
change over to the next interpolation point
For further details on the Teach procedure see section “8.2 Manual input or
„teaching“ of the interpolation points” on page 32.
5.4 Setting all registers to “Default“ values
At any time you can return all settings to the factory default values.
WARNING
This action will reset all parameters to factory default values and your own
settings will be lost. You will have to repeat your individual set-up procedure.
Factory default values are shown in the subsequent parameter tables (see
section “Parameters list” on page 34).
To reset the unit to default values:
•switch power off;
•press the NT R key on the front;
•keep NT R down while you power up again.

6 Operator menu
The menu provides one section with “Basic Parameters” (see section “ .1 Basic
settings” on page 14)and another section with “Operational Parameters” (see
section “ .2 Operational parameters” on page 16). On the display you will only
find those parameters which have been enabled by the basic settings. E.g. when
the Linearisation function has been disabled in the basic set-up, the associated
linearisation 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 -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 menu.
Detailed descriptions of all parameters will follow in section “ - Set up
procedure“ on page 14.
