DC Control Voltage Distribution – The Unit Power Supply converts
115VAC (supplied as shown in Figure 2.12) to +5VDC and the +/–12VDC
control voltages. In addition to the voltages supplied by the Unit Power
Supply, the Power Stage Interface converts 115VAC to 24VDC which is
used for relay logic and provides the supply voltage to the SCR Pulse
Transformer and Snubber boards to produce SCR gate signals for the
armature and field.
Control Common – Control Common in the Bulletin 1395 is connected
to signal ground TB10-2. Refer to Chapter 4 for installation detail.
