:: Control of tank trucks

 
 
Electronic control of tank extensions with the system „DEAD MAN“ “
 
Working and controlling circuits:
 
1 . Settings of working ways
2 . Opening and closing of foot valves, activating and turning off the pumping
3 . Time device of interval for activating of the device „Dead Man“
   
ad 1) Using the controlling blocks the operator sets the ways for opening the foot valves and initiation of the pumping.
(Closing of the by pass of the hydraulic system)
   
ad 2)

Using the electronic signal the air inlet opens into the working ways, opens quickly the foot valves, puts into service the hydraulic drive and the pumping of gas using the electronic signal occures; closes the air inlet, bleeds the working ways, interrupts the pumping and slowly closes the foot valves.

The settings of working ways remains unchanged.

In this moment the „Countdown for the activating of Dead Man 0 – x seconds is under way.

By a repeated opening of air inlet into the working ways the pumping will be started and the timer of Dead Man returns back to zero.

All functions in point 2 can be set with regard to time!

   
Ad 3) After the time of „Dead Man“ is over the time device closes the settings of working ways (in this moment the foot valves are closed, the by pass is open and the pumping is stopped) and stops the engine of the tank truck.
