Electrical connection
• The electrical connection must be performed by experienced personnel. Knowledge
of all safety instructions in these connecting and operating instructions is part of this
competence.
• The external supply voltage of 24V DC ± 15 % must guarantee safe isolation from the
mains voltage and be able to bridge a power outage period of at least 20 ms. Leuze
electronic offers suitable power supplies.
• The power supply must provide at least 1 A current reserve. Transmitter and Receiver
must be fused against overcurrent.
• It is vital during the electrical installation that the power of the machine or system to
be protected is switched off and locked, so that the dangerous movements cannot be
started unintentionally. The protective device may only be connected to the machine
after all of its safety functions have been entirely tested.
6.1
M12 connection
Transmitter and Receiver are equipped with M12 plugs. The Transmitter is equipped with a
5-pin plug; the Receiver has an 8-pin plug.
6.1.1
Transmitter
Table 6.1:
Transmitter, connection assignment
The polarity of the power supply from Pin1 and Pin3 determines the selected optical
transmission channel. If +24V DC is present on Pin1 and 0V on Pin3, transmission channel
1 is selected. If 0V is present on Pin1 and +24V DC on Pin3, transmission channel 2 is
selected.
Be sure to select the same transmission channel for both, for Transmitter and Receiver.
