RFG 5500 GENERATOR WITH DISPLAY
3-digit numeric display (seven-segment) used to
display one of three selected generator functions
(see definition of the DISPLAY SELECT switch
below).
This momentary push button switch is used to select
the desired parameter for display (subsequent
depressions of the switch cycle through the three
selections). There are three LEDs adjacent to the
switch for indicating the currently selected display
mode. The displayable parameters are:
Setpoint
•
Fwd/Load Pwr
•
Refl Pwr
•
This LED indicates that ac power is available within
the unit, all three phases are present, the main contactor
is energized, the ac voltage to the inverter section is
within the allowable voltage range, and all interlock
criteria are satisfied. When this indicator is lit, the unit
is ready to supply RF output power.
This LED indicates that RF power is on (enabled).
Depending on the selected setpoint value, RF power
may or may not be present at the output connector.
This LED indicates that the unit is unable to satisfy the
requested setpoint power due to some limit or alarm
condition in the generator. The conditions that can
cause an alarm are high VSWR, over-temperature, and
internal power limits. In the event of an over-
temperature condition, the RF On command or ac
circuit breaker must be toggled to reset the over-
temperature fault.
This LED indicates that the value being displayed is in
watts. For the RFG 5500, this indicator is always lit.
This LED indicates that the value being displayed has
been scaled and must be multiplied by 1000. For the
RFG 5500, this indicator is always lit.
