Electrical Circuit Description and Adjustment

Refer to "Section 12 - Drawings and Schematics" for the layout and
schematic drawings of all boards referenced in this section.
AC power is provided through a detachable power cable to a dual-fused power
entry module (4001-652) which contains a single-throw double-pole power
switch. AC voltages of 100-240 volts ±10% and line frequencies of 50-60 Hertz
±10% are suitable for input to the universal-input AC/DC switching power
supply (4001-653). High frequency noise disturbances on the Ground and Mains
are filtered by torroidal ferrites and additional circuitry on the AC/DC switching
power supply board.
The AC/DC switching supply (4001-653) powers the instrument through a cable
to the Main Board (4001-6044). All other electrical peripherals and boards are
connected to the Main Board. This includes a 10-key keypad, 2 line by 20
character display, tungsten lamp, Detector Board, internal printer, Centronics
port, RS232 connection, 12 volt DC cooling fan, filter wheel motor, grating
motor limit switch, and the Monochromator Drive Board.
