3 Intended use

The unit is used as a photoelectric distance sensor.

3.1 Applications

The optical distance sensor measures distances between 0.2...10 m.

• It has a background suppression at >10...19 m.
- The measured value is shown in a 10-segment display.
• 2 output signals (according to the set output function).

The distance between the sensor and the background must be limited to max. 19 m. Otherwise measured values can be ambiguous ( → Installation conditions ☐ 8)

4 Functions

4.1 Output function hysteresis

The hysteresis keeps the switching state of the output stable if the measured value varies about the sensing range. Both outputs [OUT1] and [OUT2] can be set as hysteresis function. Hysteresis function ( → 15)

4.2 Output function window

The window function enables the monitoring of a defined acceptable range. Both outputs [OUT1] and [OUT2] can be set as window function. Window function ( → ☐ 16)

4.3 Analogue function mode

An analogue signal that is proportional to the distance can be output at [OUT2]. Scaling of the measuring range (analogue output)

4.4 Switch off the laser

9.4 Programming mode

Setting a parameter value

10 Parameter setting

During parameter setting the unit remains internally in the operating mode. It continues its monitoring function with the existing parameters until the change has been completed.

10.1 General parameter setting

10.1.1 Setting a parameter value

Set the display unit [ Uni ] before the values for the parameters are defined. In case of subsequent changes of the display unit, rounding errors during internal conversion to other units may falsify the set values. Selection of the display unit (→ 15)

1	Select Parameter▶ Press [MODE/ENTER] until the required parameter is displayed.
2	Set parameter value▶ Press [SET] and keep it pressed. ▷ The current parameter value flashes for 5 s. ▶ Increase the setting value step by step by pressing the button once or continuously by holding it down.
	Decrease the value: let the display move to the maximum setting value. Then the cycle starts again at the minimum setting value.
3	Confirmation of the parameter value▶ Briefly press [MODE/ENTER]. ▷ The parameter is displayed again; the new parameter value is effective.
4	Set other parameters▶ Start again with step 1.
5	Finish parameter setting▶ Wait for 15 s or press [MODE/ENTER]. ▷ The current measured value is displayed.

10.1.2 Change from menu level 1 to menu level 2

▶ Repeatedly press [MODE/ENTER] until [EF] is displayed.
▶ Briefly press [SET].
▷ The first parameter of the submenu is displayed.

10.1.3 Electronic lock

The unit can be locked electronically to prevent unauthorised setting. On delivery the unit is not locked.

Locking

▶ Make sure that the unit is in the normal operating mode.
▶ Keep [MODE/ENTER] + [SET] pressed until [Loc] is displayed.
▷ The unit is locked.

[Loc] is displayed briefly if you try to change parameter values on the locked unit during operation.

Unlocking

▶ Keep [MODE/ENTER] + [SET] pressed until [uLoc] is displayed.
▷ The unit is unlocked.

If no button is pressed for 15 s during the setting procedure, the unit returns to the Run mode with unchanged values.

10.2 Configuration of the basic settings

10.2.1 Selection of the display unit

Set [Uni] before the values for the parameters [SPx], [nSPx], [FSPx], [ASP], [AEP] are defined. In case of subsequent changes of the display unit rounding errors during internal conversion to other units may falsify the set values.

▶ Change to [EF].
▶ Select [Uni] and set the unit of measurement. Selection of the unit of measurement: [mm], [m], [inch]
▶ Confirm with [MODE/ENTER].
▷ The selected unit is indicated by a green LED on the display.

10.2.2 Set the display

▶ Change to [EF].
▶ Select [diS] and make settings.

7 settings can be selected:

• [d1] = update of the measured values every 50 ms.
• [d2] = update of the measured values every 200 ms.
• [d3] = update of the measured values every 600 ms.
- [rd1], [rd2], [rd3] = display as for [d1], [d2], [d3] rotated by 180°. The update of the measured value only refers to the display. It has no effect on the outputs.
- [OFF] = the measured value display is deactivated in the Run mode. When one button is pressed, the current measured value is displayed for 15 s.
▶ Confirm with [MODE/ENTER].

The LEDs remain active even if the display is deactivated.

10.2.3 Configure OUT1

▶ Select [OU1] and set the switching functions.

Switching functions:

• [Hno] = hysteresis function / normally open
• [Hnc] = hysteresis function / normally closed
• [Fno] = window function / normally open
• [Fnc] = window function / normally closed

▶ Confirm with [MODE/ENTER].

10.2.4 Hysteresis function

The hysteresis keeps the switching state of the output stable if the measured value varies about the sensing range. In both cases the set and reset points are symmetrically arranged about the selected switch point [SPx]. The hysteresis is the distance between set and reset points; it is calculated on the basis of the repeatability with a safety factor of 1.5. The calculation is based on the repeatability for max. 40 klx.

Example Hno

1. For the output function [Hno] the output switches when the object approaches and when the set point (A) is reached.

[SPx]: Switch point
A: Switch-on point
B: Reset point

1. When the object is removed again, the output does not switch back before the reset point (B) is exceeded. The reset point (B) is above the set point (A).

[SPx]: Switch point
A: Switch-on point
B: Reset point

If the output function [Hnc] has been selected, the set and reset points are reversed. The output switches off when the object approaches. When the object is removed again, the output switches.

Switching state of the outputs

Output function	Object distance (D)	switching status
[Hno]	D < [SPx]	Closed
	D > [SPx]	Open
[Hnc]	D < [SPx]	Open
	D > [SPx]	Closed

10.2.5 Setting of the switch point for hysteresis function OUT1

▶ Under [OU1], select the output function [Hno] or [Hnc].
▶ Confirm with [MODE/ENTER].
▶ Select [SP1] and set the switch point.
▶ Confirm with [MODE/ENTER].

10.2.6 Window function

It is possible to define a window for the object recognition for each of the two outputs (OUT1 / OUT2).

Switches off when the object is detected

[nSPx]: switch point "near"
[FSPx]: switch point "far"
FE: window

If the measured value is between the switch point “near” [nSPx] and the switch point “far” [FSPx], the output is opent (if [OUx] = [Fnc]).

Switches when the object is detected

[nSPx]: switch point "near"
[FSPx]: switch point "far"
FE: window

If the measured value is between the switch point "near" [nSPx] and the switch point "far" [FSPx], the output is closed (if [OUx] = [Fno]).

Switching state of the outputs

Output function	Object distance (D)	switching status
[Fno]	D < [nSPx]	Open
	D > [FSPx]
	[nSPx] < D < [FSPx]	Closed
[Fnc]	D < [nSPx]	Closed
	D > [FSPx]
	[nSPx] < D < [FSPx]	Open

Both window limits([nSPx] and [FSPx]) work with a switching hysteresis.
