1.11. DC Power Distribution Plate (Unit 1 A13)
The DC Power Distribution Plate control is through the E-Stop Panel (Unit 1 A12). When any
component on the DC Power Distribution Plate is not functioning (with the exception of the
Lightning Protection Module), follow the troubleshooting procedures in this section.
When the operator presses the E-Stop Button, the Safety Relay (K2) removes DC Power from
the Contactor (K1). When the Contactor (K1) is OPEN, AC Power is removed from the main DC
Power Supplies (PS2, PS3, PS4) which provide DC power to the Pedestal (Unit 2). Should the
24VDC Power Supply (PS1) fail, all DC Power will fail.
