CAN Integration with BBA Pump Controller

APN0041  |  Revision 1.0  |  June 27, 2025

This note provides wiring, configuration, and scripting guidance to connect a Senquip QUAD to a BBA LC40 pump controller over J1939/CAN. It lists key PGNs/SPNs for engine speed, temperatures, fuel level, and controller state, and shows how to parse them into variables with correct scaling. Example logic implements remote start/stop and mode changes with safety interlocks, watchdogs, and confirmation reads. A commissioning checklist covers termination, grounding, and EMC practices near large engines. The result is a robust remote monitoring and control link, enabling fleet‑level visibility and automated run‑hour capture for pumps in dewatering and bypass operations.
