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.
