The programmable electronic controller is configured to provide a test actuation signal to the motor upon receiving a test close signal. The valve control system further comprises a gas detection input configured to receive a gas detection signal. Receipt of the gas detection signal at least partially meeting a first criterion causes the emergency close signal to be supplied to the controller.
