4-6 Electrical Connections
Hint:
When wiring to F3SS components, leave the wires just long enough to allow the printed circuit board to be
withdrawn to the extent allowed by its stops. For ease of connection and servicing, OMRON recommends the
use of 18 AWG wire when connecting the F3SS to a machine control system.
4-6-1 Emitter Electrical Connections
The only connections which can be made inside the emitter are those for input power. Terminals for input power
are provided on terminal block J3 at the bottom of the board. The printed circuit boards are labeled for proper
connection.
4-6-2 Receiver Electrical and Control Connections
Control and electrical connections are made inside the receiver on terminal block J5 at the bottom corner of the
board. Terminal positions and functions are as follows:
4-6-3 Long cable length installation for Receiver
For a receiver installed with a cable greater than 9mm(30 feet) in length and a load of less than 50mA. A load
resistor, 1 K ohm, 1 watt (provided in hardware kit) must be installed between the output (+) and output (-) at
the destination point of the solid-state output.
WARNING
All electrical connections must be made by qualified personnel only and in accordance with local and
national electrical codes and regulations. Shut off all power to the machine and the controller before connect-
ing. Never allow any metal filings or chips to enter a F3SS enclosure and possibly impair the function of the
F3SS.
