1.9 Transducer Wiring (continued)
1.9.1 Single Resolver Transducers (continued)
Figures T1.8 and T1.9 show connections to AMCI transducers that use our standard MS-16 connector. For
units that do not use the MS-16 connector, refer to the transducer’s specification sheet for connection infor-
mation. Specifications sheets can be found on our website at:

When connecting a transducer from another manufacturer, use the R1-R2 and S1-S4 designations to deter-
mine how to correctly attach the transducer to the NX2A4E2.
1) There are two ways to reverse the count direction when using single resolver transducers.
One method is to set the Count Direction parameter when programming the NX2A4E2. The
other method is to reverse the connections on one of the stator pairs. AMCI standard
method is to reverse the S2-S4 pair, which is the green/black pair of the CTL cables.
2) When using a foreign single resolver transducer, note how the signals are paired in the
AMCI CTL cable and use this pairing when generating your wiring diagrams.
3) The cable shields must be isolated from earth ground at the transducer to prevent ground
loops and ground shifts. If using a junction box, treat the cable shields as a signal carrying
conductor at the junction. Do not tie the shields to earth ground at the junction box.
4) The cable shields must be isolated from earth ground at the transducer to prevent ground
loops and ground shifts. When using a foreign transducer, do not attach the shields to a
transducer pin, even if this follows the standard of your transducer’s manufacturer.
1.9.2 Size 11 and Size 15 Resolvers
Figure T1.10 shows the connections required to attach a resolver with industry standard wire colors to a
Belden 9730 cable. If these connections are followed, you can refer to Figures T1.8 and T1.9 on page 38 for
connections from the Belden cable to the NX2A4E2.
