OY51 Measuring light grids (10 mm beam spacing) 2 Safety instructions • The unit described is a subcomponent for integration into a system. – The system architect is responsible for the safety of the system. – The system creator undertakes to perform a risk assessment and to create documentation in accordance with legal and normative requirements to be provided to the operator and user of the system.
Measuring light grids (10 mm beam spacing) OY51 3 Intended use Transmitter (T) Receiver (R) Detection zone Detection field width Detection field height The OY51 light grids are multi-beam optoelectronic devices and consist of one transmitter and one receiver.
OY51 Measuring light grids (10 mm beam spacing) 4 Getting started For fast set-up, carry out the following steps: u Fix the transmitter and the receiver Installation (Ò / 8). u Connect the receiver to an IO-Link master and establish a connection to the unit.
The IODDs necessary for the configuration of the unit, detailed information about process data structure, diagnostic information, parameter addresses and the necessary information about the required IO-Link hardware and software can be found at www.ifm.com.
OY51 Measuring light grids (10 mm beam spacing) 6 Installation 6.1 Installation instructions The operating conditions at the mounting location must not affect the functioning of the optoelectronic sensors. Please note especially: • The transmitter and the receiver must not be affected by intensive light sources (emitters, sunlight etc.).
Measuring light grids (10 mm beam spacing) OY51 Adjustable brackets can be used to ensure easy optical alignment www.ifm.com. 6.1.2 Optical alignment Transmitter Receiver The LEDs of the receiver help to correctly align the optoelectronic sensors. u Align the transmitter so that the green LED of the receiver lights.
