PHOTOELECTRIC MEASUREMENT LIGHT CURTAIN Micron light curtains MUST NOT be used as safety devices for protection of operators in hazardous areas. INTRODUCTION The Micron photoelectric light curtain is a multi-beam optoelectronic system consisting of an emitter and a receiver, used to detect or measure objects. The two units can be synchronised via optical link or cable.
PHOTOELECTRIC MEASUREMENT LIGHT CURTAIN Working range Particular operating conditions may affect the sensing level of photo-electric devices. In environments characterised by fog, rain, fumes or dust, to always guarantee correct operation of the appliance, it is advisable to apply suitable correction factors Cf so as to maximum working range values. In these cases: Pu = Pm x Fc where Pu and Pm are, respectively, the working and maximum range expressed in metres.
PHOTOELECTRIC MEASUREMENT LIGHT CURTAIN ELECTRICAL CONNECTIONS Perform the connections as shown in below tables, in order to ensure the correct functioning of the barrier. We recommend the use of separate power supplies for the barrier and for other electrical power equipment (electric motors, inverters, frequency converters) or other sources of disturbance.
Ground connection Table 5 - M12, 5-pole RX (C models) Micron-PC connection via USB cable (ReeR CSU M5 - 1250900) AC/AV/B models are fitted with an M5 connector (leading from the receiver) for connecting the light curtain to a PC on which the Micron configuration SW is installed.
PHOTOELECTRIC MEASUREMENT LIGHT CURTAIN Push-Pull Outputs (models with step 10mm, 20mm, 30mm STANDARD MODELS) The models with step 10mm, 20mm, 30mm STANDARD (not H models) are provided with digital outputs 0-24VDC Push-Pull type. This outputs can operate both in PNP and NPN mode. At the power-on the barrier recognizes the type of connection of the load and operates accordingly.

At power on: GREEN • 2 slow blinks -> Low range • 2 fast blinks -> High range ORANGE BLINKING No synchronisation via cable Figure 7 RECEIVER (AC/AV/B)
* If more than one zone is obstructed, the data refer to the zone with the highest number of obstructed beams. A graphic interface can also be displayed for real-time monitoring of light curtain conditions. The following figures illustrate some screen pages of the ReeR MicronConfigurator program which can be used to configure the Micron's operating logic. Preliminary Operations Insert the MICRONCONFIGURATOR CD-ROM in the computer and follow the software installation instructions.
PHOTOELECTRIC MEASUREMENT LIGHT CURTAIN Connecting/disconnecting the light curtain The "Barrier characteristics" panel in the top left corner is filled in automatically a few seconds after establishing the USB connection. Click (upload) to send the configuration to the Micron: at the end of this procedure the light curtain will automatically restart using the new configuration.
PHOTOELECTRIC MEASUREMENT LIGHT CURTAIN INPUT PIN CONFIGURATION (2) Figure 11 Input pin configuration (2) The input pin can be configured as follows: No function (disabled). Trigger function: this can be used to enable analog and digital outputs, stand-by and start/stop measurements. In this mode the minimum internal trigger time can be set to between 0 and 250 ms.
PHOTOELECTRIC MEASUREMENT LIGHT CURTAIN TEACH IN mode (3) When the input pin is configured as Teach in the “Teach in mode” panel is active Teach in mode is used when the light curtain must recognise a specific object or pattern. There are three possible options: MODE DESCRIPTION The object to be recognised must be compact (with no transparent...

Use the “ENABLE” box to select the conditions for activating each analog output. MODE DESCRIPTION Output disabled...
PHOTOELECTRIC MEASUREMENT LIGHT CURTAIN Digital output configuration (5) DIGITAL OUTPUT CONFIGURATION (5) Figure 14 The conditions for activating each digital output can be selected in the "ENABLE" panel. MODE DESCRIPTION Output disabled The output is not active and gives 0 VDC The output is active and gives 0 VDC or 24 VDC depending on the set condition.
PHOTOELECTRIC MEASUREMENT LIGHT CURTAIN The CONDITION box The “CONDIZIONE” box can be used to set the condition for switching the output to LL1 (24 VDC): First select operator 1 in the left-hand column. Select the condition: Select the value. The program offers a choice of the following conditions: •...

PHOTOELECTRIC MEASUREMENT LIGHT CURTAIN Micron on Network Micron barrier can be connected on Network; the maximum number of barriers is 3. • The first barrier will be programmed with node=0. • The other barriers will have a node sequential and different from 0 numeration. •...
The Checksum field is only present if selected in the “Data transmission parameters” section. In “Metron simulation” mode the barrier will send data simulating the METRON B in “Binary” mode. In “FieldBus” mode must be selected when the barrier is coupled with a ReeR FieldBus module. 8541124 - 12/12/2018 - Rev.6...
