STATUS INDICATORS

The RFG 1251 generator provides the following status indicators located on the connector
panel:

Table 4-5. Status Indicators

AC ON This green LED indicates that ac power is available within the generator.
RF ON This green LED indicates that the RF output is enabled. Depending on the
setpoint value, RF power may be present at the output connector.
Following an ac power up of the generator, RF power is inhibited until the
RF ON CMD signal is transitioned from off-to-on.
Interlock Open This yellow LED indicates that the required interlock criteria have not
been satisfied and, subsequently, RF power is inhibited. If the interlock
loop is closed, the RF output is enabled at the next off-to-on transition of
the RF ON CMD signal on the User port. The LED remains lit as long as
the interlock loop is open.
