Operating Instructions
General The Model 8578A100GIG has no operating controls. When
installed the only requirement is for the interlock switch to
be connected to the RF power source. After applying an air-
flow ³ 1000 ft
3
/min (28.32 m
3
/min) to the inlet grill the unit
is now ready to accept RF power. Once the unit is set, there
is no need for the presence of an operator.
Load Power
WARNING
Surface can reach temperatures in excess of 100°C
when maximim power is applied to load.
WARNING
Limit the interlock terminal to less than 30 Vrms.
Although the interlock terminal is rated to 230 Vac,
the potential for electrical shock exists.
CAUTION
Do not apply more than the rated RF power to the
load. Excessive RF power will damage the load resistor.
Do not operated above the rated capacity; i.e. 10kW of
power. The unit will handle a small percentage of overload
until the interlock system’s sensor relay opens due to over
temperature and turns off the transmitter. If a large
amount of overloading occurs, resistor failure is eminent be-
fore the interlock system reacts.
Shortly after load power has been applied, the RF line may
be too hot to touch. Disconnect only while following the Shut
Down procedure.
Operation
Under
Normal and
Abnormal
Conditions
The interlock is for proper operation at the maximum rated
ambient condition of 40°C (104°F).
The normally closed relay opens at 86°C ± 3°C (186.8°F
±5.4°F) and closes at 80°C ±3°C (176°F ±5.4°F).
Shut Down When operation of the load has been completed, follow these
steps for shut down.
1. Turn transmitter off.
