3.1 Startup
When power is applied to the UCP (and assuming the
Control Breaker
is engaged), the
Control Power
lamp will be lit
indicating the system is powered. This indicator also functions as a lamp and audible alarm test button. Pressing
Control
Power
will momentarily illuminate all indicators, and trigger the audible alarm.
All normally closed (N.C.) -001 models power up in the EPO mode — as though the EPO button had
been pressed. The EPO Reset button must be pressed before beginning normal operation.
3.2 Control Modes and Connector Pins
The system has three modes or states of control named On, Off, and EPO. These modes change the state of the Outlet
Control Bus pins at the rear of the unit—which are then interpreted by the remote EPO controller in a Marway PDU (or
other equipment with compatible signals).
The following table summarizes the pin connections during the operating modes.
