A revolutionary failsafe for Sub-Drivers

[type viic]

This failsafe is a unconventional one, which is a time limit failsafe, and without a gas saver unit.
This one will prevent you diving when your gas tank was empty, you can forget the dive & surface cycles when a voyage with a full charge. when your gas tank is low gas, the failsafe will locks the gas servo to blow, and preventing diving again.
If you use the failsafe, you'd better record your sub driver's gas tank total blow time with a stopwatch(no blow cycles) at first, and setting a safe blow time limit for count down. The save time=total gas blow time - one blow time of sub from underwater to surface - one blow time of sub from underwater to surface.
This one is suit every types Sub-Driver, you can setting the best blow time by yourself (MIX 20 secs.)
function:
1.ordinary failsafe,when signal loss, It will control gas servo to blow, unless restart the failsafe switch.
2 safe blow time, if your setting a safe blow time for your Sub-Driver, it will control gas servo to blow when your gas tank low gas, unless restart the failsafe switch.

Everyone!
If you use Sub driver or other gas tank WTC for your sub, you must keep the maximum time of gas tank blow for a voyage. If you exhaust the gas, when you can not command your sub to dive again.
If you forget the maximum time of gas tank blow, and your Sub driver's gas tank is empty, when you command your sub to dive, and you must to salvage your sub in the sequel.
My failsafe can help you to keep the maximum time automatically. For example, If your Sub driver's gas tank total blow time is 15 seconds from full to empty in a full charge, you can setting the safe blow time 15 seconds or less (you'd better setting 13 or 12 seconds for unknown variable) in the failsafe. when you first command the gas servo to blow, the 15 seconds or less count down begin , when you stop command the gas servo to blow, count down pause, and when you command the gas servo to blow again, count down continue. so when the count down end, the failsafe will lock the gas server to blow automatically（like loss signal), unless you restart the failsafe.
The MIX 20 seconds is meaning you can setting 1-20 seconds in this version, but if you need, we can make a long time one like 1 minute version.
