1.
Open the existing HG-1 manual tuner case. (Refer to the
figure below). Take care not to damage the tuning capacitor
by setting the frequency to its lowest setting.
2.
Remove the existing knob and pointer (save them for
potential future use).
3.
Remove the existing mounting screws securing the 6:1
reduction drive (save any spacers or nuts).
4.
Remove the temporary nuts securing the two spacers
attached to the HG-1 motor assembly.
5.
Attach the HG-1 motor assembly to the capacitor shaft.
6.
Using the supplied longer #4-40 screws, mount the HG-1 motor assembly to the 6:1 reduction drive.
7.
Tighten the set-screws and reinstall the HG-1 manual tuner case back.
Adjust the torques sensor and replacing the battery (The HG-1 Remote Tuner Retrofit only)
The red Stall light illuminates when the capacitor has reached the CW and CCW position. Because there
is some variation in 6:1 reduction drive torque, the sensor can be calibrated.
1.
Refer to the figure below. Open the back of remote tuner case by removing the four screws. Note
the blue miniature potentiometer located on the interface
board.
2.
Set the Rate to Max and while pressing the UP and Down
buttons adjust blue potentiometer so that Stall light
illuminates when the Capacitor reaches the CW and CCW
ends. It is normal for the Stall light to flicker occasionally. (You
may have to repeat this adjustment as the 6:1 reduction drive
loosens over time).
3.
The battery may also be replaced at this time. Battery life
depend on type and use. Generally, it should last for extended tuning session. Turn the remote off
when not in use.
4.
Replace the back cover of the remote tuner being careful not to pinch any of the wires.
Deploying the HG-1 Remote Tuner
1.
Make sure the HG-1 Magnetic Loop antenna is placed in an obstruction free area.
2.
For better water protection, the HG-1 motor drive assembly may be mounted facing down.
3.
Connect both ends of the supplied cable (common Ethernet cable) to the motor assembly and
controller.
4.
Turn the HG-1 Remote Tuner on; the green SBY LED should illuminate.
5.
Set the Rate control to its Max position.
6.
While observing the motor assembly, push the red Up or green Down buttons. Note the motor
turning CCW or CW depending on the button pushed. This is an indication that the system is
correctly connected and everything is in order. If the red Stall LED comes on, that is also OK. It just
means you have reached the limits of the tuning range.
