Control transrormer
On the primary side of the control transformer there
are four terminals for 208, 220, 240 and 480 volt, and
a neutral terminal. There are two secondary windings,
one of which has a centre tap. The secondary
voltages are 11-14 volt and 2 x 12-16 volt. The
diagram of the transformer is given below. On the
secondary side there are references to the second
board terminal numbers for the control voltages.
