Antenna: Description and Operation
UP OPERATIONWhen the Radio is turned on, the Radio (DeVille with UX1) or the Remote Radio Receiver (all except DeVille with UX1) applies battery voltage through circuit 145 to energize the Antenna Relay. With the Antenna Relay energized, the relay, contacts close connecting relay terminals C1/A and C2/B. The closed contacts allow voltage from Fuse C9 (DeVille/Concours) or Fuse D7 (Eldorado/Seville) and CKT 2140 to be applied to the Antenna Motor through the DK GRN wire.
The Antenna Motor now runs to raise the antenna raise since the motor is now grounded by G401. The motor's ground path to G401 passes through the Antenna Motor's up switch, the GRY wire and the energized Antenna Relay Once the mast is fully extended the up switch in the Antenna Motor open. The Antenna Motor now stops since it is no longer grounded.
DOWN OPERATION
When the radio is turned off, voltage from the Radio (DeVille with UX1) or the Remote Radio Receiver (all except DeVille with UX1) is no longer applied to the Antenna Relay's coil causing the relay to de-energize.
With the relay de-energized the relay contacts close to connect relay terminals C1/A and C2/C to each other. These closed relay contacts now allow voltage from Fuse C9 (DeVille/Concours) or Fuse D7 (Eldorado/Seville) and CKT 2140 to be applied to the Antenna Motor through the Antenna Motor's down switch. The motor is grounded through the DK GRN wire, the Antenna Relay and CKT 1250 to G401. The motor now runs in the opposite direction because the polarity if the motor terminals has changed.
The Antenna Mast will now be pulled down until it is fully retracted. At that point, the down switch contacts open, turning off the Antenna Motor.
