In this state, the RF amplifier system cannot be activated via the remote interface. When the switch is in the LOCAL position, the remote interface shall only be able to shut down the RF amplifier system.

Figure 1: Local Control State Diagram

The state changes shown in black shall be made only when the LOCAL/REMOTE switch is in the LOCAL position. Enabling the RF amplifier system with the switches shall not be possible in REMOTE mode. The state changes shown in red shall be made at any time regardless of the position of the LOCAL/REMOTE switch.

From the OFF state, the RF amplifier system shall be activated on by pressing the STANDBY/RESET switch followed by the ON switch. It shall not be possible to go directly from OFF to ON.

The RF amplifier system’s default state shall be OFF. In the OFF state the DC power supplies shall be off, and the RF transistors gates inhibited. When STANDBY/RESET is pressed, the DC power supplies shall turn on and RF transistor drain voltages applied. This button also resets any fault conditions that may be latched in the RF amplifier system. When ON is pressed the RF Transistor gates shall be activated, bringing the RF amplifier system into a completely enabled and ready state.

The system can be returned to the OFF state in a single step by pressing the OFF button, or in two steps by pressing STANDBY/RESET followed by OFF.

The current state of the control shall be indicated by a LED illuminator under each pushbutton.

There shall be a digital power meter to monitor the forward and reflected power of the RF amplifier system. The accuracy shall be +/- 2.0% into 50 Ω, over the entire dynamic range.

Power shall be displayed in kilowatts. The display shall be located on the front of the rack.

Power monitoring shall also be available through the remote interface (see §3.1.19).

3.1.18 LED Status Indicators

The status of the RF amplifier system shall be indicated locally by a LED array on the front of each rack.
