Power Switch
The power switch is located above the relays and in between the AC and
DC fuses (see Figure 1). The power switch turns the incoming AC power
source on and off at the Beacon 200. When the switch is up, the power
switch is on.
NOTE: The DC power input has no on/off switch and is not affected by the
position of this switch.
Power Supply
The power supply is mounted to the power supply mounting plate which is
located behind the display PCB. The power supply mounting plate is
mounted to the main PCB with four standoffs. The power supply receives
the AC input from the external power source and converts it to a DC
voltage that is usable by the Beacon 200 circuitry.
