T1 Transformer & Control Voltage 115 VAC
T1 - Control Transformer
T1 is the schematic designation
of the control transformer. A
step-down transformer (T1)
reduces the incoming line
voltage to levels suitable for use
with the Xe control system. The
reduced voltage sources are
called secondary circuits.
The secondary circuit is rated at
115Vac, 1 phase, 60Hz and is
used to energize solenoid valves and starter coils. The
“hot” connection is X1 and the neutral connection, X3,
is grounded to the starter chassis.
Ensure transformer is grounded according to the
electrical schematic of the machine.
