NOTE:

Once the reserve air chambers have been fully charged to their pre-set working pressure, there will be no change in chamber pressures even as the unit is being modulated, unless there is an interruption to the air supply.
If the air supply is broken or disconnected the internal versa valve contained within the control chamber will switch and close down the Actuator.
The chamber pressure will be reduced by approximately 25%, after failure the Actuator will remain inoperative until the air supply is restored.

If an electrical failure occurs, the Solenoid valve coil will de-energise allowing the Solenoid spool valve to move to the rest position and the Actuator will close.
During and after electrical failure the air chambers will remain at full working pressure, the Actuator will remain inoperative until the power supply is restored.
