Transducer Cabling (continued)
Installation Guidelines
In the United States, the National Electrical Code cable type used for the transducer cable is
CM (Communications, General Purpose cable). Therefore the installation of the cable falls
under Article 800 of the National Electrical Code and must be followed. Note that this does
not preclude the possibility that your local code or company policy is more restrictive.
The shields of the transducer cable must be grounded at the ANS1 only! The Shield pin on the Transducer
Input Connector is brought to the chassis pin on the power supply connector.
When installing the cable, treat the shield as a signal carrying conductor. If you must splice the cable, it must
be done in a junction box. Follow these guidelines:

Do not strip the shield back any further than needed to make the splice.

Do not connect the shield to ground at any junction box or the transducer. This will eliminate ground
loops that could damage the ANS1 and prevent ground shifts from damaging the cable or controller.
Single Resolver Transducers
Pre-assembled and tested transducer cables can be purchased for most of the AMCI transducers that are com-
patible with the ANS1. The part number for the cable is CTL-(x), where (x) is the length in feet. The follow-
ing diagram shows how to wire a standard AMCI single resolver transducer to the ANS1.
Figure 4.5 AMCI CTL Cable Wiring
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 ANS1. 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 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. 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.
