    2.2 ELECTRICAL WIRING 2.2.1 Signal Cable Anderson recommends the use of 18-24 AWG, 4 conductor cable. In addition, it should be foil shielded with a continuous drain wire (If Factory supplied, Belden #9534 or equivalent). Although only two conductors and the drain wire are utilized, cable as specified above will retain its roundness when inserted into the seal-tight grommet.

In turn, this unit typically sends an output that is used to throttle a feed valve.

  • Page 16: Section 3 Maintenance And Troubleshooting

    3.2 CALIBRATION CHECKS 3.2 CALIBRATION CHECKS To maintain proper accuracy, Anderson recommends yearly ZERO signal (4.00 mA) checks. A record of these readings will help to maintain a consistent schedule. If re-zeroing does not correct inaccuracies seen in the receiver, calibration of the receiver itself should be performed.

  • Page 17: Troubleshooting

    If signal is proper, approximately 4 mA with no product on sensor, then problem is with external wiring. NOTE: Be sure to observe proper polarity as described in Figure 2-3 If any of the above indicate a transmitter problem, call your local distributor, or Anderson Technical Service directly.

  • Page 18: Appendix A - Warranty And Return

    These products are warranted to be free from functional defects in materials and workman- ship at the time the products leave the Anderson factory and to conform at that time to the specifications set forth in the relevant Anderson instruction manual or manuals, sheet or sheets, for such products for a period of two years.
