Product Introduction
Hyundai MSU‑111C‑HEEM‑3 is a motor auto control unit designed for industrial and marine motor starter panels. This HEEM‑2 series module handles start/stop commands, sequential motor staging, and timing functions with adjustable timers for parallel running (0.5–25 sec), pressure build‑up (0.5–25 sec) and sequential starts (00–100 sec). It’s commonly used in group starter panels where automated motor sequencing and protection are required.
MSU‑111C‑HEEM‑3 applies to systems where coordinated motor control prevents overloads and optimizes mechanical load engagement. Adjust the timing parameters to match your drive profile and verify control logic wiring with the OEM schematic before installation. Timer ranges and fault outputs vary by panel configuration, so reference the OEM manual.
