5.3 Wiring Notes for Robot Controller I/O Connectors (NPN

type)

After the wiring of the controller's I/O connectors is completed, check the following

before turning ON the power:

Check point (1)

Using a circuit tester, check across the "+24V terminal" and "0V terminal" of each

connector and across the "E24V terminal" and the "E0V terminal" to see that there is

no continuity. See the figure below and the table given on the next page.

Caution: If the connector wiring between the Robot Controller's "+24V

terminal" and "0V terminal" and between the "E24V terminal" and

the "E0V terminal" is shorted, damage to the power circuit of the

Robot Controller will result.

Check point (2)

Using a tester, check across "each signal Output terminal" and "+24V terminal" or

"E24V terminal" of each connector to see that there is no continuity. See the figure

below and the table given on the next page.

Caution: If the wiring between "each signal Output terminal" and "+24V

terminal" or "E24V terminal" of each connector is shorted,

damage to the Output circuit and power circuit of the Robot

Controller will result.

Caution: Wind adhesive vinyl tape around all ends of the unconnected

wiring of each connector to prevent them from contacting other

wiring and parts, which results in shorting.
