    If it is not possible to make all spans equal, choose span lengths that reduce the total power consumption of the CPT that powers the HDU. Do this by minimizing the length of Span 1 and Span 2. Use on page 26 when you calculate the electrical length of each span.

  • Page 35: Appendixc - Ground Faults

    AULT The HDU-409 has Ground Fault Detection (GFD) circuits as described in R7-1, Section 7.2.1 of GR-1089 CORE, Issue 1, Revision 1, December, 1996. When used with HiGain line units, ground faults occurring at any point along any span are immediately detected. Ground fault conditions shut the HiGain circuit down.
  • Page 36: Higain Fault Isolation

    This forces the circuit down immediately. If the circuit stays up, either the GFD circuit is defective or the HDU-409 is not properly grounded. HDU-409 A grounded pair is being detected by the HDU-409 in Span 2. Remove shuts off HDU-409 and check for ground fault in Span 2.
  • Page 37: Pg-Flex Fault Isolation

    With the HDU-409 doubler, a ground fault after very short the doubler on Loop 2 has the same affect. On Loop 1, however, the DC bursts power does not shut off because of a ground fault. When there is a ground fault on Loop 1, the doubler limits its output voltage to approximately -40V.
