Terminal/connections description
TB1-1 – Connection to SCR snubber circuit used to extract energy
from the snubber for SPGDB operation
TB1-2 – Connection to SCR sensing resistor which indicates
conduction status of SCR being operated
TB2-1 – Positive 20V power supply connection to temperature
sensor board. Provides power to temperature sensor board.
TB2-2 – Common connection of positive 20V power supply to
temperature sensor board
TB3-1 – Positive 15V power supply connection for test power
used when commissioning drive or testing SPGDB
TB3-2 – Provides artificial sense voltage signal to allow SPGDB
to gate the SCR when in test mode. When the appropriate
test power cable is used, P/N 81001-262-51, this input is
shorted to TB3-1 to obtain the sense voltage.
TB3-3 – Common connection of positive 15V power supply used
for test power
TB4-2 – Cathode connection to SCR being controlled
TB4-1 – Gate connection to SCR being controlled
OP1 – Blue fiber optic cable receptacle – Firing pulse command
from the processor
OT1 – Grey fiber optic cable receptacle – Diagnostic status of
the SCR
