This section describes the following operations.
1) Pressure drain (releasing) pilot circuit
2) Pressure drain (releasing) main circuit
Purpose :
To release the main circuit pressure for piping repair work.
Mechatronics :
When press screen change switch of gauge cluster and buzzer stop switch at the same time for more than 5 seconds, mechatro controller recognizes this is pressure release control and out puts the following command.
1) Puts out the minimum tilting command value to the pump proportional valve (PSV-P1, PSV-P2).
2) Puts out a pressure release control revolution command value to the governor motor. (Electric system).
3) Travel straight solenoid proportional valve (PSV-C) is input the command value to change the pressure release position.
4) Puts out a standby command value to the P1, P2 bypass cut proportional valves. (A command that does not put out the secondary pressure of the P1, P2 bypass proportional valves).
Hydraulics :
1) The pump proportional valve minimizes the delivery rates of the P1, P2 pumps.
2) The secondary pilot pressure for the travel straight valve pressure release position selection comes out of the travel straight proportional valve (PSV-C), flows into the PTb port of C/V (2) and switches the travel straight valve to its pressure release position.
When the operating lever is shifted to neutral during engine running, if the pressure is drained (released) as mentioned left, "DRAINING HYD. PRESS" is displayed on the gauge cluster and intermittent buzzer sound continuously. If the operating lever for the circuit required releasing pressure is operated four to five times, pressure draining may be completed. After draining pressure is completed, turn off the starter key, and buzzer stops. If the pump pressure is determined to be more than 9.8kgf/cm2 (140 psi) by the output value of the high-pressure sensor or the high-pressure sensors (SE-22, 23) are broken, "FAIL DRAIN HYD. PRESS" is displayed on the gauge cluster and the buzzer sounds continuously. In that case, also the buzzer is not stopped unless the engine key is turned to off. Repeat the pressure releasing procedure once again.
If the travel straight valve is turned to the pressure release position, the oil delivered by each pump is unloaded to the tank passage. If the spools are switched by pilot operation, the remaining pressure from the actuators may be relieved to the tank circuit, i.e. the main circuit pressure may be released.
