Claim Text:
1. A testing system for testing a valve system including a valve controller, a valve actuator, a solenoid valve, and an emergency shutdown valve, the testing system comprising: a test panel including: a test input device configured to generate a test input signal; a timer for reading a duration of the test input signal; a verification device configured to verify that the duration of the test input signal is valid to initiate a test; a transmitter device configured to communicate a start test signal to the valve controller in response to a valid duration of the test input signal verified by the verification device and initiate the test to cause the valve controller to proceed with a test routine by controlling the solenoid valve; a first output indicator configured to indicate when a valve stroke test start signal was sent from the test panel to the valve controller; a receiver device configured to receive signals from the valve controller including one or more of a position sensor signal, a pressure sensor signal, a current sensor signal, a loop current signal, a travel set point signal, a travel signal, and a digital valve controller startup signal provided to the valve controller device during the test by one or more of the valve actuator, the solenoid valve, and the emergency shutdown valve; and a second output indicator configured to indicate a state of the test by interpreting the one or more of the position sensor signal, the pressure sensor signal, the current sensor signal, the loop current signal, the travel set point signal, the travel signal, and the digital valve controller startup signal, received from the valve controller, wherein the first output indicator indicates that the valve stroke test start signal was sent independent of the state of the test.
