Page Line Ground Fault Re-generation
When a ground fault is detected at a remote LE200-RM Line Extender, the ground fault can be duplicated
on the local Page/Party
® system cable. DIP switch SW5 position 3 enables regeneration of the ground
fault. Refer to Figure 6 for the location of switch SW5 on the Main PCBA and Table 8 below for setting
options.

1. The ground fault regeneration feature is used in SmartSeries systems to allow a ground fault on the
remote cable segment to be detected by the system control cabinet. Disable this feature if the Line
Extender is not installed in this type system.

Page Line Ground Fault Output Contact
The Model LE200-RM provides a relay contact that activates whenever a ground fault is detected on the
local page line, remote page line or both the page lines. The ground fault detection feature (described
above) must be enabled. The contact output can be used to activate an external device or system which
annunciates the fault condition. The DIP switch SW5 positions 4 and 5 configure which page line ground
faults activate this contact. Refer to Figure 6 for the location of switch SW5 on the Main PCBA and Table
9 below for setting options.
