Interlock
The Apex generator provides a system interlock connection through the User port.
The RF output connector is also interlocked by a series switch that is part of the
system interlock.
Optional Water Solenoid
The Apex generator provides water solenoid control circuitry that can be accessed
through a connector on the rear of the generator. When an optional water control
solenoid is connected to the water solenoid control circuitry, the Apex generator
controls operation of the solenoid and water flow. This feature minimizes
condensation in the generator when the RF output is off and cooling water is still
circulating through the generator.
Grounding
The Apex generator has two holes located on the rear panel to attach the system RF
ground to. One is a tapped M-6 hole, the other is a 5/16
″ x 18 tapped hole. Either hole
may be used to provide an appropriate ground. Select the appropriate hole depending
on whether you use metric or American fasteners.
Protection
The Apex generator protects itself from damage from the following conditions.
• Any unmatched load condition at the generator output. Output power fold-back
(limiting) occurs as required by the generator protection circuits.
• Any internal over current condition not directly related to the output load
condition as protected by current limiting or fuse.
• Excessive internal temperature. (This condition may be caused by lack of proper
cooling water flow, excessive ambient operating temperature, or other causes.)
• Any combination of input ac line phase drop out.
• Input line brown-out (under voltage) or over voltage.
• Any User/ port pin shorted to chassis or another port pin.
THEORY OF OPERATION
In this section a bock diagram is designed to help the User understand the process by
which the Apex generator works. Following the diagram is an explanation of the
diagram in a table to help the User utilize the Apex unit as well. Figure 2-1 and Table
2-1 describe the basic operation of the Apex generator.
