I just received a Caswell ADF with failsafe. (ADF16).
Instructions are great, but I seem to have a problem getting the ballast/failsafe circuit to work.
On initial power up, ADF green & red go through self check OK, but immediately afterwards red starts to flash rapidly ("fast blink") MODE. joystick ballast command is inoperative. I have ADF pitch & ballast on channels 3 & 4 respectively.
Channels 1 & 2 work fine even while ADF is fast blinking red.
When I shut down receiver, solid red light goes on & ballast servo does go to full command.
Batteries (both Rx & Tx) are fully charged, unit polarity correct.
Removal of the ADF unit restores normal control functions.
I have not adjusted the failsafe POT, as it is not easily adjustable due to its construction; (POT blade indents are shallow with a small protrusion from the center of the POT so screwdriver blade cannot catch the POT indents securely). I need to modify my screwdriver for this, but reading instructions, I do not think that affects signal, just ballast control movement.
Any help appreciated,
Thanks
Steve
