  • Patent number: 9080683
    Abstract: A method for conducting a partial stroke test of an emergency shutdown valve includes receiving a request to initiate the partial stroke test from a user interface or another source, establishing a direct or an indirect wireless communication link with the emergency shutdown valve, and generating one or more commands of a digital industrial automation protocol to be transmitted to the emergency shutdown valve via the wireless communication link, so that a partial stroke test of the emergency shutdown valve is initiated in response to these commands.
    Type: Grant

  • Patent number: 7852610
    Abstract: A device intended to meet flameproof approval requirements is configured to have two compartments separated by an energy-limiting barrier. The first compartment of the device houses the wiring terminations that bear ignition-capable energy and, therefore, must be flameproof. The energy-limiting barrier is configured to limit the energy that can reach the second compartment to a level that is not ignition capable. This allows the second compartment to be safe without meeting the flameproof requirements, and allows user-interface elements such as switches and indicators to be designed in a more cost-effective manner.

  • Patent number: 7079021
    Abstract: An emergency shutdown test system, wherein the emergency shutdown test system includes an emergency shutdown device controller and sensors to provide data to the controller, the controller having a processor, a memory coupled to the processor and an auxiliary input, wherein an emergency shutdown test is stored in the memory, and the auxiliary input is adapted to receive a binary signal and sensor data. Routines are stored in the memory and are adapted to be executed on the processor to cause the emergency shutdown test to be performed in response to the receipt of the binary signal at the auxiliary input and to cause sensor data to be recorded in the memory during the emergency shutdown test.
