powerless state

4.1 Power supply

The unit accepts DC power 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 auxiliary output). In specific models, 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 LD30x-P4-... are designed for either 24 Vac or 42 Vac power supply and the screw terminals are marked correspondingly. LD305 has -P4- option only, i.e. 17Vdc 30Vdc power supply. 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.

NOTE

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 7 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 7 instead.

MAN LD30x E 1.2.odt Electrical connections 14 of 48

LD30x

4.3 Inputs A, B and Reset

In the basic set-up menu (see the “7.1 Basic settings” section on page 24) 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).

NOTE

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.

Typical input circuit (standard version with HTL inputs):

PNP

4,7k

GND GND

+24V int.

NPN

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. Furthermore, a current output 0/4 – 20 mA is available. Both outputs refer to the GND potential and the signal polarity changes with

MAN LD30x E 1.2.odt Electrical connections 15 of 48

LD30x

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. 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.

WARNING

Voltage output and Current output cannot be used together! Please never connect mA output and V output simultaneously!

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:

ENTER

(Input)

SET

(Setting)

CMD

(Command)

The functions of the keys are depending on the current operating state of the unit. The following three operating states apply:

• Normal display state (see the “5.1 Normal display state” section on page

18)

• Set-up state (see the “5.2 Selection and setting of parameters” section on page 19)

- Basic set-up (see the “7.1 Basic settings” section on page 24)

- Operational parameters set-up (see the “7.2 Operational parameters” section on page 26)

• Teach operation (see the “5.3 Teach operation” section on page 20)

5.1 Normal display state

NOTE

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 ENTER and SET down simultaneously for 3 seconds

Operational parameter set-up

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 linearisation. For more details please refer to the “8.1 Linearisation“ and “8.2 Manual input or “teaching“ of the interpolation points” sections on page 40.

5.2 Selection and setting of parameters

5.2.1 Selecting a parameter

The ENTER key will scroll through the menu. The SET 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 ENTER 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 SET 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 SET key, the current 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 current setting, press the ENTER key, which will also automatically scroll forward the menu.

NOTE

At any time the unit changes from programming mode to normal display operation, when you keep the ENTER 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 ENTER yet would remain unconsidered.

5.3 Teach operation

NOTE

The time-out function remains disabled during all Teach operations.

Key Function

ENTER key will terminate or abort any Teach operation in

progress

SET 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 the “8.2 Manual input or “teaching“ of the interpolation points” section on page 42.

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 the “ Parameters list” section on page 44).

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.

6 Operator menu

The menu provides one section with “Basic Parameters” (see the “7.1 Basic settings” section on page 24)and another section with “Operational Parameters” (see the “7.2 Operational parameters” section on page 26). 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 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 menu. Detailed descriptions of all parameters will follow in the “7 - Set up procedure“ section on page 24.

7.5.1 PC-Mode

Communication in PC mode allows free readout of all parameters and registers of the unit. The example below shows the details of communication for serial readout of the current display value.

This is the general format of a serial request string:

EOT AD1 AD2 C1 C2 ENQ

EOT = Control character (Hex 04) AD1 = Unit address, High Byte AD2 = Unit address, Low Byte C1 = Register code, High Byte C2 = Register code, Low Byte ENQ = Control character (Hex 05)

EXAMPLE

Request for the current display value from unit number 11.

ASCII-Code

EOT 1 1 : 1 ENQ

Hexadecimal

04 31 31 3A 31 05

Binary

0000 0100 0011 0001 0011 0001 0011 1010 0011 0001 0000 0101

Upon a correct request the unit will respond as shown on the right. Leading zeros will be suppressed. BCC represents a block check character generated from an Exclusive-OR of all characters from C1 through ETX (inclusively).

STX C1 C2 x x x x x x x ETX BCC STX = Control character (Hex 02) C1 = Register code, High Byte C2 = Register code, Low Byte x x x x x = Register data ETX = Control character (Hex 03) BCC = Block check character

With incorrect request strings, the unit only responds STX C1 C2 EOT or just NAK.

Provided the current display value of the unit is "-180" for instance, the full response of the unit will be as shown below:

ASCII

STX : 1 - 1 8 0 ETX BCC

Hex

02 3A 31 2D 31 38 30 03 1C

Again BCC represents the block check character formed from the Exclusive-OR of all characters from C1 through ETX.

7.5.2 Printer-Mode

The Printer mode allows cyclic or manual activation of transmissions of the specified register data. The corresponding register can be specified by means of parameter S-CodE. Another parameter called S-mod allows the selection between two different string types:

“S-mod“ Transmission string type

“Print1“

Space Sign Data Line

feed

Carriage return

+/- X X X X X X LF CR

“Print2“

Sign Data Carriage

return

+/- X X X X X X CR

The mode of activation of serial transmissions can be determined as follows:

Cyclic (timed) transmissions

Set the S-tim item (see on page 35) to any value ≥

0.010 sec. Select the desired string type next to the S-mod parameter.

After exiting the menu the timed transmissions will start automatically.

Manual activation of transmissions

Set the S-tim item (see on page 35) to 0.000. Select the desired string type next to the S-mod parameter.

After exiting the menu a transmission can be activated at any time by shortly pressing the ENTER key.

8 Special functions

8.1 Linearisation

This function allows a non-linear input signal to be converted into a linear representation or vice versa. 16 interpolation points are available, they can be freely arranged over the whole measuring range at any distance. Between two points the unit will interpolate automatically straight lines. It is advisable to set several points into areas with strong bending and to use only a few points in areas with little bending. “Linearisation Mode“ has to be

set to either 1-qUA or 4-qUA (see LmodE item in the “7.1 Basic settings” section) to enable the linearisation function (see drawing below). Parameters P01_x to P16_x select 16 x- coordinates, representing the display values which the unit would normally show in the display. With parameters P01_y to P16_y you can specify which values you would like to display instead of the corresponding _x values.

This means e.g. that the unit will replace the previous P02_x value with the new P02_y value.

NOTE

• With respect to the consistency of the linearisation, the x- registers have to use continuously increasing values, e.g. the x- registers must conform to the constraint P01_x < P02_x < … < P15_x < P16_x.

• Independently of the selected linearisation mode, the possible setting range of all registers P01_x, P01_y,…, P16_x, P16_y is always

-199999 … 999999.

• With measuring values lower than P01_x the display will always show P01_y.

• With measuring values higher than P16_x, the display will always show P16_y.

P1(x)= 0 P1(y)= 0

Linearization Mode = 1_quA

Linearization Mode = 4_quA

P1(x)= -1000 P1(y)= 900

P8(x)= 0 P8(y)= 750

P16(x)= +1000 P16(y)= - 600

8.2 Manual input or “teaching“ of the interpolation points

Interpolation points to form the linearisation curve can be entered one after each other, using the same procedure as for all other numeric parameters. This means you will have to enter all parameters P01_x to P16_x and P01_y to P16_y manually using the keypad.

WARNING

During manual input of interpolation points the unit will not examine the settings P01_x to P16_x. Therefore the operator is responsible for adherence to the constraint P01_x < P02_x < … < P15_x < P16_x.

In most cases it should however be much more convenient to use the Teach function. For this method we have to move the encoder, step by step, from one interpolation point to the next. After each step we enter the desired display value through the keypad.

How to use the “Teach” function

• Please select the desired range of linearisation (see the “7.1 Basic settings” section on page 24).

• Hold down the CMD key for 3 seconds, until the display shows tEACh. Now the unit has switched over to the Teach mode. To start the teach procedure please press again the CMD key within the next 10 seconds. The display will then show P01_X.

• With respect to the consistency required for linearisation, all parameters from P01_x to P16_ y will be overwritten by suitable initial values first. Initial values for P01_x and P01_y are -199999 and all other values will start with 999999.

• Press once more CMD key to display the current encoder position. Then move the encoder to the first of the desired interpolation points.

• When you read the x-value of your first interpolation point in the display, press CMD key again. This will automatically store the current display value in the P01_x register. For about 1 second you will read P01_Y on the display, followed by the same reading again that has been stored previously.

• This display value now can be edited like a regular parameter and you can change it to the desired P01_Y value.

• When you read the desired P01_Y value in your display, save it by pressing CMD key again. This will cause the display to automatically scroll to the next interpolation point P02_x.

MAN LD30x E 1.2.odt Special functions 42 of 48

LD30x

• Once we have reached and stored the last interpolation points

P16_x/y, the routine will restart with P01_x again. You are free to double-check your settings once more or to make corrections.

• To finish the Teach procedure, keep ENTER key down for about 2 seconds. In the display you will read StOP for a short time and then the unit returns to the normal operation. At the same time all linearisation

points have been finally saved.

NOTE

• The unit will examine the constraint valid for the x-values of interpolation points. Every interpolation point must be higher than its preceding point. If this constraint is breached, all 6 decimal points will blink automatically as a warning. Pressing the CMD key will not store

the illegal value, but result in an error text E.r.r.-.L.O..

• To exit the teach mode again, you have the following two possibilities:

1. Press the ENTER key for 2 seconds. On the display you will read

StOP for a short time and then the unit will switch back to the normal mode.

2. Just do nothing. After 10 seconds the unit will switch back to the

normal mode automatically. In both cases the parameters of linearisation P01_x to P16_Y will not change.
