connecting it to the body moulding. Fit the locking device in the
orientation shown in Fig. 6 and push firmly in.
other end of the loop or any base along the loop to verify the wir-
ing up to that point. If there is no voltage out at any measured
point, this may be due to:
1)
Loop Open Circuit - wiring incomplete to part of the loop.
2)
Incorrect Polarity -FC450IB Isolator bases will appear as a
short circuit if they are wired with incorrect polarity.
3)
Loop Short Circuit - If this occurs between two FC450IB Isola-
tor bases, it will isolate that section of the line, which will then
appear as an open circuit. If this occurs between the supply
and the first FC450IB Isolator Base, the supply output will go
low due to the internal current limit.
