Page Line Ground Fault Detection and Transmission
The Model LE200 Line Extenders provide page line ground fault detection on the local Page/Party ®
system cable. Additionally, when a ground fault is detected, the LE200 can transmit the ground fault to
the more remote LE200 so that it is duplicated on the remote Page/Party
®
system cable. If multiple
LE200s are connected to the same Page/Party ® system cable segment, only one page line ground fault
detector may be enabled. A three-position header, P5, and its shorting clip control page line ground fault
detection. DIP switch SW5 controls page line ground fault regeneration.

P5 Shorting Clip Page Line Ground Fault Detection
Pins 1-2* Page line ground fault detection is disabled.
Pins 2-3 Page line ground fault detection is enabled.
Removed Page line ground fault detection is disabled.
N OTES :
1. If connecting an LE200 to the same system cable segment as an ADVANCE Page/Party
®
Interface
(PPI) card, disable the LE200 page line ground fault detector and enable the PPI card ground fault
detector. If both ground fault circuits are enabled simultaneously, intermittent SmartSeries FSK data
errors will occur between the PPI card and SmartSeries stations.
2. Changes to this parameter take effect without cycling power.
3. *Indicates default position.
Table 17. Page Line Ground Fault Regeneration Setting on 69443-xxx PCBA
SW5-3 Page Line Ground Fault Regeneration
Open* Page line ground faults are not regenerated locally.
Closed Page line ground faults are regenerated locally.
N OTES :
1. The expected use of the ground fault regeneration feature is within ADVANCE systems. If used in
Page/Party
®
systems, this feature should be disabled.
2. Changes to this parameter take effect without cycling power.
3. *Indicates default position.
