The DC Power Supply also provides the voltages that enable hot insertion of the option cards and SCUs. The DC Power Supply does not, however, provide the voltages necessary to power individual option cards or the SCUs as each card has itis own DC-DC supply. In addition, the DC Power Supply in slot PS-A provides alarm relay output functionality. If only one DC Power Supply is used, place the DC Power Supply in PS-A to provide alarm relay facilities.

A power failure condition takes precedence over other failures; both a power and temperature failure condition results in a fast blinking RED LED. Amber (slow blink) Over-temperature condition Test LED Off Description Not used If power is applied to the ATLAS 890 unit and there is no active Controller, the front panel LEDs will be in an indeterminate state. The controller must complete its power up sequence before the LEDs are valid. Functionality The ATLAS 890 AC Power Supply furnishes
