This simulates a loss of supply pressure, causing the switching valve to trip. Note Use a single power source for both the analog output AO card providing loop current to the digital valve controller and the solenoid valve.
This ensures power will be maintained to the solenoid valve so long as power is maintained to the AO card. Figure 6. During this time, the digital valve controller cannot provide control.
An engagement delay of 1. Note While the valve is in a locked state, the set point from the digital valve controller may change in response to changes in process conditions. This change in set point may result in a process bump when control is restored to the digital valve controller. Also visit our website at www.
