City-Tie Module
The City Notification Card (Figure 3-11) provides connection and
operation for Local Energy, Shunt type Master Box and Reverse
Polarity styles of output. The output type is selected by choosing
which terminals terminate the field wiring. The module has an Am-
ber LED to signify disconnect status. The ability for individual out-
put isolate is provided through the system operator menu.
Local Energy-Type Output:
Monitored output for trip circuit wir-
ing and Master Box coil status (Set/Unset), current limited at
550 mA, 24 VDC. Monitored for open, short and ground fault.
Shunt-Type Output:
Unsupervised contact rated at 5.0 Amp,
24 VDC resistive.
Reverse Polarity-Type Output:
Unsupervised output for trip
circuit wiring only, current limited at 100 mA, 24 VDC.
Reverse Polarity output circuits are listed for use in Power Lim-
ited applications. Refer to Drawing. No. 06-235443-008 for fur-
ther installation details.
The City Tie Module will operate during
PEGAsys'
“FailSoft”
mode. Any system alarm will cause the output to transfer.
In Walk Test mode the city notification outputs shall be disabled.
In addition, the output has provisions for manual disable or iso-
late through the operator menu function. The initiation of a walk
test will institute a system trouble causing the city tie output to
transfer to the trouble state.
