[Control input connection for failure detection]
The function of detecting failures in iring ith e ternal control output e uipment can only be set to control
input terminal . or iring for hich failure detection is performed, insert resistors as sho n belo
or instructions on setting the failure detection function to the control input terminal, see p. 3- , ONT O
N T S TT N S.
Notes
• e sure to connect resistors as sho n in the gure belo . The failure detection function ill not ork
correctly if no resistors are connected, or if resistors of different values from those specified are used.
• To ensure stable NX-300 operation, it is recommended that failure detection iring be made independent
from that of control input terminals 1 , for hich shielded t isted pair cables shorter than 10 m 3 . 1 ft
should be used.
• onnect the cable s shielded ire to the NX-300 s signal N terminal.
