When the BVC display throws a fault mid-lift and your roller stops adapting amplitude, this 182-page Bomag BW 177 service manual PDF (OEM 008 099 94) has the answer, and it covers the 213 and 226 DH-4 BVC single drum rollers under the same cover. Circuit diagrams with component listings and connector overviews close out the book, backed by hydraulic schematics and an error code section that turns each fault reaction into a concrete check.
The BVC exciter system gets its own chapters: gear pump, valve block, swashing motor, acceleration transducers, and the potentiometer adjustment your compaction readings depend on. Set steering pressure to 200 bar plus or minus 10, verify the proportional solenoids between 0.4 and 1.2 A, and confirm the CAN bus terminator at 120 ohms.
Every hour a roller sits with a dead exciter, the fill schedule slips. Bookmarked and text-searchable, this download helps you trace a circuit to the failed component on the first try.
