FAQ

Q: Is the 138945-01 a standalone module that slides into the 3500 rack?

A: No, the 138945-01 is an internal main board. It is typically housed inside a 3500 series monitor module casing and acts as the internal processing unit for that specific module.

Q: Does this board come pre-loaded with firmware?

A: While the hardware is ready for installation, the specific configuration and firmware version may need to be updated using the 3500 Rack Configuration Software to match your existing system's revision level.

Q: How do I know if the 138945-01 is the correct board for my 3500 monitor?

A: You should verify the part number on the internal PCB of your current module. This board is commonly used in several 3500 series monitor variations, but matching the exact 138945-01 designation is vital for compatibility.

Q: Can this main board be repaired if it fails?

A: Due to the high-density surface-mount components and the critical safety nature of the 3500 system, Bently Nevada generally recommends replacing the entire board with a new 138945-01 to ensure system reliability and warranty compliance.

Q: What is the environmental durability of this internal board?

A: It is designed to operate within the standard temperature and humidity specs of the 3500 rack, featuring industrial coatings to resist the effects of atmospheric contaminants commonly found in petrochemical and power plants.
