Functions and features

The unit is used as an optical distance sensor.

Applications

• The optical distance sensor measures distances of 1…75 m on the reflector.
• It has a background suppression at > 75…150 m.
• The measured value is shown in a 10-segment display.
• According to the set output functions, 2 output signals can be generated.

Functions

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. → 10.2.4 Hysteresis function

Output function window

The window function enables the monitoring of a defined acceptable range. Both outputs (OUT1 and OUT2) can be set as window functions. → 10.2.6 Window function

Analogue output function

The sensor can also output an analogue signal on output 2 (OUT2) which is proportional to the distance. → 10.2.11 Scaling of the measuring range (analogue output)

Switch off the laser

For safety and maintenance purposes the laser of the unit can be temporarily switched off via the input on pin 5.

Installation

Installation conditions

• Install the unit so that the reflector to be detected is within a measuring range of 1…75 m.

The unambiguity range of the sensor is fixed to 150 m. Reflections within a range

• 75…150 m are suppressed.

Reflectors in the direct beam path of the sensor – also in the range > 150 m – are to be avoided by the customer. Otherwise, the measured values can be ambiguous.

Mounting accessories

The unit is supplied without mounting accessories.

Electrical connection

The unit must be connected by a qualified electrician.

• The national and international regulations for the installation of electrical equipment must be adhered to.
• Ensure voltage supply according to EN 50178, SELV, and PELV. O1D106: cULus, Supply Class 2
• Disconnect power.
• Connect the unit as follows:

O1D106 PNP

Core colours of ifm sockets:

• 1 = BN (brown), 2 = WH (white), 3 = BU (blue), 4=BK (black), 5 = GR (grey).

Operation with IO-Link master

The unit is compatible with the IO-Link master port class A (type A).

For operation with IO-Link master port class B (type B) observe the following:

As a standard, the unit is not compatible with master port class B (type B). Pin 2 (OU2) and pin 5 (IN1) are used for manufacturer-specific functions. That means that the main supply voltage of the unit and the additional voltage supply (master port class B on pins 2/5) are not electrically isolated

With the following configurations, the unit can be used with master port class B:

• Connect unit and IO-Link master via 3 wires: Connect pins 1, 3 and 4 of the unit with the IO-Link master (do not connect pins 2 and 5).
• Connect unit and IO-Link master via 4 wires: Deactivate pin 2 (OU2) via
• IO-Link (setting OU2 = “off”) and connect pins 1, 2, 3 and 4 of the unit with the
• IO-Link master (do not connect pin 5).

Explanation of the menu

For the factory settings please refer to the end of these instructions (→ 14 Factory setting).

Operating modes

Run mode

The run mode is the normal operating mode. After power on the unit is in the Run mode. It carries out its monitoring function and generates output signals according to the set parameters. The display indicates the current distance, the yellow LEDs signal the switching status of the outputs.

Display mode

Indication of the parameters and the set parameter values.

• Press [MODE/ENTER] briefly.
• The unit goes to the Display mode. Internally it remains in the operating mode. The set parameter values can be read.
• To scroll through the parameters, press [MODE/ENTER] briefly.
• To display the respective parameter value, press [SET] briefly.
• After 15 s the unit returns to the Run mode.

Object reflectivity – orientation value for the signal strength

• Press [SET] in the Run mode.
• The unit displays an orientation value for the signal strength (e.g. +100 means max. signal strength and full repeatability. A lower value, e.g. +020, means decreasing signal strength and restricted repeatability).

Programming mode

Setting the parameter values → 10.1 Parameter setting in general.

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 finished.

Parameter setting in general

Setting of the parameter value

Select the display unit [Uni] before you define the values for the parameters. In case of subsequent changes of the display unit rounding errors during internal conversion to other units may falsify the set values. 10.2.1 Selection of the display unit

Change from menu level 1 to menu level 2

Electronic lock

The unit can be locked electronically to prevent unintentional settings. On delivery the unit is not locked.

Timeout

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

Configuration of OUT1

Hysteresis function

The hysteresis keeps the switching state of the output stable if the measured value varies about the sensing range. In either case set and reset points are symmetrically arranged around 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.

Example Hno

1. For the output function [Hno] the output switches when the object approaches and when the switch point (A) is reached.
2. When the object is removed again, the output does not switch back before the reset point (B) is exceeded.
   • The reset point (B) is greater than the set point (A).

When the output function [Hnc] was selected, set and reset point are reversed. The output is switched off when the object approaches. When the object is re- moved, the output switches on.

Switching the status of the outputs

Output function Object distance (D)            Output status

[Hno]| D < [SPx]| Closed
D > [SPx]| Open
[Hnc]| D < [SPx]| Open
D > [SPx]| Closed

Example of output function [Hno]

Sampling rate 33 Hz, distance to the object 2 m:
Hysteresis = ± 15 mm (→ 10.3.3 Table repeatability and accuracy) x factor 1.5 = 22.5 mm

• Reset point 2 m + (22.5 mm) = 2.02 m
• Set point 2 m – (22.5 mm) = 1.98 m

Setting of the switch point for hysteresis function OUT1

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 open (when [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 (when [OUx] = [Fno]).

Switching the status of the outputs
