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 5/16x 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.
