Pump Wireing & Control

I have started to wire up the DOL and control panel for the hydraulic pump. I have added an Start/Stop button to the control panel, this controls the pump to tank solenoid valve which shorts out the supply in its off state. Once the motor is started, the solenoid can be switched on using the start button which ports the pump to the main output connector. If there is a loss of power or the stop button is pressed, the solenoid switches back to the off position until start is pressed again.

Should be getting 3 phase installed later in the week so I can test things out!
