Operating Instructions

Normal Operation

Bird 8920 series loads have no indicators or operating controls. They require no special operating procedures or surveil-
lance when their performance limits are not exceeded. Follow the instructions for the specific transmitter 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 prop-
erly 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

The vent plug must be used at all times when the unit is operating or cooling. Failure to do so could result in an

explosion or severe burns.

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.
