Disconnect power. Also, disconnect any independently supplied relay load circuits.
The nominal voltage is 24 V DC; this voltage may vary between 19.2 V and 28.8 V.
In case of a single fault, the supply voltage must not exceed a maximum of 28.8 V DC.
Therefore, a safe separation between current supply and transformer is necessary.
To guarantee functional reliability an output capacity of min. 2000 µF / A has to be ensured if a
power supply with diode bridge is used.

7.3 Synchronisation of transmitter and receiver
To ensure a reliable function of the measuring light grid, the transmitter and the receiver must be
synchronised. The two units can be synchronised optically Optical synchronisation (
cable Synchronisation via ifm Y cable (EY5053 and EY5054) (
11). The settings are made via
IO-Link.
7.3.1 Synchronisation via ifm Y cable (EY5053 and EY5054)
The transmitter and the receiver can be synchronised using ifm Y cables (EY5053 or EY5054). They
must be wired according to the figure.
