circuit, the alarm circuit, and RF source(s). Turn the user supplied main power switch
"ON" and enable the transmitter. Operate the transmitter as desired. To stop operation, it
is necessary to first turn off the transmitter. The fan may continue to run for some time.
This depends upon the power level at which the load was operating and upon the ambient

Coaxial Loads with fans operates in "Standby" or "Reject" mode with the blower off.
1-7. Operating and Adjustment Controls. No field adjustments are necessary or possible.
1-8. Electrical Description. Models sold with fans contains a 50-ohm non-reactive resistor
assembly capable of dissipating a total of their rated watts of applied electrical energy at
frequencies between DC and 110MHz with a maximum VSWR of 1.10 to 1. No provisions
are made for tuning the resistor assembly and all operating controls relate to the operation
of the optional fan assembly. The fan control circuit consists of two switches wired in
parallel to control the fan motor. Power is supplied to the fan whenever the equipment is
attached to the correct power supply and the user supplied main power switch is "ON" and
the fan thermal switch senses a temperature equal to or greater than 120

thermal switch wired to terminals (C,D) on the Amphenol four pin cylindrical twist lock
connector located on the front panel of the unit. There is no interlock circuit provided for
units sold without fans. The alarm circuit consists of one normally closed 372°F thermal
switch wired to terminals (A,B) on the Amphenol four pin cylindrical twist lock connector.
