[TowerTalk] US Tower Remote Kit (need a solution)

[bill steffey NY9H]

when i bought my hdx572 i was not going to give UST $ 1000 for
a remote box....

first a reminder, with your manual switch .... while the tower is 
going down , flip the switch to up.... take BIG notice that IT IS 
STILL GOING DOWN.
xxxx  YOU HAVE JUST SWITCHED TO THE UP LIMIT SWITCH.
NOW, STOP THE TOWER...  AS THE LIMIT SWITCH WILL NOT STOP THE TOWER. 
You must allow the motor to stop ...before changing directions,
or else ....you will NOT have the correct limit switch in line.

SOOOO  when I installed my remote system, I included 2 nice plug-in 
delay relays...( thanks ebay  6$ ea) ....

the inside switch ( where I can see & HEAR the tower...)  or a switch 
in the tower base enclosure chooses    up/off/down... another switch 
determines control point  in/out.

The delay relays fire two large contactors which I already had, which 
are good for 100A @ 220.  and handle the motor currents easily.( the 
delay relays did not).

Listening to the motor and tower grind and squeak proves to be a 
great tool for assuring oneself of system longevity.  If it does not 
sound just right...
I'll wander out the 150 feet.
last four pix here have my drawings....  crude
