C&e Petrochina

The document describes a shutdown system with 6 classes of shutdown (A-C, X) triggered by different conditions. Class A shutdown is always active, Class B activates after a timer expires when a crank pull button is actuated, and Class C activates when a setpoint is met. The system includes pressure transmitters on the 1st and 2nd stage suction and discharge lines that trigger shutdowns according to high and low pressure limits. Shutdowns are annunciated through local displays like lamps.
