Missing Pulse Failsafe (AFS) Installation

I installed the AFS in the forward WTC, and it will automatically control one or two Clippard valves if radio signal is lost for more than 7 seconds. The Clippard valves will blow the ballast tank(s) with CO2 gas.

If, after the AFS activates the valves and radio signal is regained, the valves will close and operation will continue as normal. This is as straightforward as I can make it ... keeping it simple!

It´s a little difficult to see in the pics, but the AFS is installed onto a clear Lexan® sheet with double sided 3M® tape. The clear Lexan® was used for two reasons; to raise the AFS up from the electronics board, and to be able to see/run tubing and wires underneath the AFS.
