for the HFV generator to deliver power. The HFV generator will continue to
deliver power until the set point level falls below the output off threshold, or until
the
RF on
command is disabled (see command
At Set Point Indicator Off
When the output is enabled (
RF On
indicator lit) and the
At Set Point
indicator is off,
the power output is not meeting the set point (or requested power level). This can be
caused by an internal or external (load) fault condition.
Note:
The output must be enabled (
RF On
indicator must be lit) before the
At
Set Point
indicator will illuminate. If the
RF On
indicator is off, see
INTERNAL FAULT CHECK
To check for internal faults, see
“Running Internal Diagnostics” on page 5-18
HFV generator passes this test, then proceed to the following section; otherwise,
contact AE Global Customer Support (see
“AE Global Customer Support” on
).
EXTERNAL LOAD CHECKS - OPEN/SHORT RF OUTPUT
PATH
Use extreme caution, as this section involves troubleshooting the output of the HFV
generator.
There are four basic components that could impede the RF path: the HFV generator
output connector, the output cable, the tuner, or the chamber. Complete the following
steps.
1. Turn the rear circuit breaker off to ensure that there is no RF power at the output
of the HFV generator.
For the HFV generator output connector:
a. Remove the output cable and visually inspect the output connector for signs of
arcing or heat stress.
b. Verify an open is measured between the center conductor and outer shield.
c. Make sure the output connector is mounted firmly to the chassis.
Use suitable precautions; this area contains high voltages that could
cause serious injury or death.
