SYSTEM TO MANUALLY INITIATE AN EMERGENCY SHUTDOWN TEST AND COLLECT DIAGNOSTIC DATA IN A PROCESS CONTROL ENVIRONMENT

摘要

An emergency shutdown test, wherein the emergency shutdown test system includes an emergency shutdown device controller and sensors to provide data to the controller. The emergency shutdown device controller has a processor, a memory coupled to the processor and an auxiliary input couple to the processor, wherein an emergency shutdown test is stored in the memory, and the auxiliary input is adapted to receive a binary signal and sensor data. A first routine is stored in the memory and is 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. The memory is also adapted to store a second routine, wherein the second routine is adapted to be executed on the processor to cause sensor data to be recorded in the memory during the emergency shutdown test. The processor compares a plurality of predetermined limits to the received sensor data to determine if the valve is fully operational or if possible problems exist.
