Additional Notes:The AECM: After a 5 minute delay (to allow for Actuator replenishment), energises the Vent Valve baulk solenoid through internal Hi and Lo side switching which releases the latch and allows the Vent Valve to return to its Normal position 0.5 second after the Vent Valve is reset the electrical supply is restored to the IVs, thus reconnecting the Normal hydraulic supply. The delay ensures the Vent Valve is in the neutral position and the hydraulic system has stabilised before full pressure is applied.
