B37V046170 / C37V048170 / A37V046170

The B37V046170 / C37V048170 / A37V046170 is a drive‑unit circuit board for motor and/or water‑drive systems in industrial sheet‑fed offset printing machines, principally for Man Roland presses (e.g., the 700 series). It controls the water‑drive or motor‑drive subsystem, providing signal and power regulation to the associated motor assembly. Using this board as replacement restores drive control and synchronisation of the associated water‑drive or motor‑drive unit. Before installation, always verify the part number, the machine’s serial number and control‑system version to ensure correct substitution.
