CABINET (Cabinet Sensors)
The Compact Modular Cabinet (CMC) AC Power Supply (650A) supports one
alarm lead that indicates the state of both the power and fan. With multiple
cabinets, alarm leads from each cabinet are tied into a single lead. The CMC uses
variable speed fans to reduce noise. The CMC power unit contains Thermal
Speed Control and an alarm circuit. A variable speed fan has a 3-pin connector for
the variable input power for speed control and its alarm circuitry.
See the next table for the LED and alarm conditions.
