4.3 Wiring Notes for 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.
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 circuit tester, check across "each signal output terminal" and "+24V
terminal" or "E24V terminal" of each connector to see that there is no continuity.
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.
