Operating Instructions
Normal Operation
Bird 8890 series loads have no indicators or operating controls. They require no special operating procedures or
surveillance when their performance limits are not exceeded. Follow the instructions for the specific generator
equipment.
Operation Under Abnormal Conditions
The load can be subjected to moderate overloads for short periods. If this is likely, make sure the interlock is
properly connected to prevent damage to the load.
Shutdown
These loads are passive devices, so have no way of being turned off. Turn off RF power at the source.
Emergency Shutdown
Turn off RF power at the source.
If the interlock thermoswitch is properly connected, RF power will be automatically turned off when the coolant
temperature reaches an unsafe level.
WARNING
Never attempt to connect or disconnect RF equipment from the transmission line
while RF power is being applied.
Leaking RF energy is a potential health hazard.
