TSC 80e TRANSFER SWITCH CONTROLLER
PM091 Rev 0 09/01/21 Thomson Technology
48
XFER TO GEN Contacts change state when the controller
signals a transfer to the generator position.
SWITCH FAILURE Contacts change state when the transfer switch
mechanism fails to operate for the given time
delay period.
UTIL PWR OK Contacts change state when the utility supply is
energized and is within programmed voltage,
frequency and phase balance limits on all
phases.
GEN PWR OK Contacts change state when the generator
supply is energized and is within programmed
voltage, frequency and phase balance limits on
all phases.
ATS NOT IN AUTO Contacts change state when the TSC 80e
operating mode is not in the AUTO operating
mode. This condition will occur when the
external switch (e.g. FTS4) or internal Test
Modes is programmed in any other mode other
than Auto.
ATS IN AUTO Contacts change state when the TSC 80e
operating mode is in the AUTO operating mode.
This condition will occur when the external
switch (e.g. FTS4) or internal Test Modes are
set in the Auto Mode.
LDC XFER TO GEN Contacts change state when the TSC 80e
operating mode is programmed for LDC
function and a transfer is initiated from the
Utility supply to the Generator supply.
LDC XFER TO UTIL Contacts change state when the TSC 80e
operating mode is programmed for LDC
function and a transfer is initiated from the
Generator supply to the Utility supply.
LDC XFER TO GEN/UTIL Contacts change state when the TSC 80e
operating mode is programmed for LDC
