PUMP GP-PISTON 2896359 - Caterpillar

Note: Revision 5 is now used as the Monitor Software. The Programmable Logic Controller has been updated.Note: Revision 5 will calculate the engine setpoints by using the engine rpm. The alarm setpoint and the shutdown setpoint will be calculated by the software. Refer to Engine News, SEBD9288, "Software Available for Programming Allen-Bradley Programmable Logic Controller".When a fault code is received on the "PLC Status Screen", the following information can be used in order to troubleshoot the problem.When a major fault is encountered, a hex code is written to S:6. Major faults can be one of the following types:Non-User (1) - The routine does not run.Non-Recoverable (2) - The routine runs for 1 pass.Recoverable (3) - The fault may clear S:1/13 in order to resume operation.
