FAQ

Q1. Who is LAUER and what is its core business?

A: LAUER is a German automation manufacturer headquartered near Stuttgart, with over 30 years of history. Its core business is the development and production of industrial HMI (Human-Machine Interface) solutions, including operator panels, networked displays, and industrial Panel PCs. LAUER focuses on providing durable, flexible, and integrated control and visualization platforms for industries such as power generation, marine, automotive, food & beverage, and metallurgy.

Q2. What are LAUER's main product families and their purposes?

A: · LCA / PCS series – Text displays and basic operator panels for simple parameter setting, status monitoring, and machine control.

 · WOP series – Networked graphic panels designed for modern factory communication and data exchange (Ethernet, Profibus, CANopen, etc.).

 · VPC / Panel PC series – High-performance industrial Panel PCs running Windows CE or full operating systems. These can integrate SoftPLC (IEC 61131-3), combining display, control, and data processing into one device.

Q3. How reliable are LAUER's industrial panels in harsh environments (e.g., marine, heavy industry)?

A: LAUER products are designed for extreme conditions:

· They hold major marine classification society approvals, making them suitable for high humidity, salt spray, and vibration on ships.

· Their power supplies tolerate wide voltage fluctuations, and their enclosures protect against dust and electrical interference.

Q4. What are the most common failure modes of LAUER operator panels and how are they repaired?

A: The most frequent failures include:

· Backlight failure / dark screen – Caused by aging CCFL tubes or LED driver boards. Repair involves replacing the backlight unit or driver circuit.

· Touchscreen malfunction – Non-responsive or erratic touch due to damaged touch film or controller. The touch overlay can be replaced independently of the LCD.

· Communication port damage – RS232, RS485, or Ethernet ports failing after power surges or wiring errors. Typically repaired by replacing the corresponding protection components or interface ICs.

· Power supply board failure – Burnt capacitors or voltage regulators. Repaired by replacing discrete components on the internal power board.

· Most LAUER panels are repairable at the component level, which is more cost-effective than full replacement.
