Step 2. Wiring Configuration and Cable Termination
Determine a wiring configuration according to the number of safety edges (sensor) in series. (Up to 5 safety edges can be connected in series.)
There are five types of cable termination for both ends of the safety edge. The method can be selected from the combinations of 2-wire cable,
cable with M8 connector (male or female), and terminating resistor as shown below.
Note: 1. To connect safety edges in series, two types of methods are available : Using a 2-wire cable or M8 connector.
2. To connect with an edge controller, a 2-wire cable should be used. There is no polarity.
*
Use of a terminating resistor is required on one side of the last series-connected safety edge.
Configuration Example
Using one safety edge (Configuration No. 2 x 1)
Using two safety edges
Connecting using 2-wire cables
(Config. No. 0 x 1) + (Config. No. 2 x 1)
Connecting using connectors
(Config. No. 5 x 1) + (Config. No. 4 x 1)
Using N safety edges
Connecting using 2-wire cables
(Config. No. 0 x (N - 1)) + (Config. No. 2 x 1)
Connecting using connectors
(Config. No. 5 x 1) + (Config. No. 3 x (N-2)) + (Config. No. 4 x 1)
