Lauer PCS950.000.5 Control Panel PG 950.103.0

Product Overview

The Lauer PCS950.000.5 (version PG 950.103.0, also known as PQ1140) is a high‑performance operator control panel originally developed for Branson ultrasonic welding machines. It features a large graphic display and a comprehensive keypad, providing operators with full control over welding parameters, process monitoring, and diagnostic access. The panel is fully compatible with the standard LAUER PCS950 series and can be used as a general‑purpose HMI for other industrial equipment requiring a rugged, feature‑rich interface.

Display and Graphical Interface

The panel is equipped with a 10.4‑inch TFT colour display with a resolution of 800 x 600 (SVGA) and a bright LED backlight (500 cd/m²). The screen offers a wide viewing angle (80° in all directions) and a contrast ratio of 500:1. It supports both text and full‑colour graphics, enabling the creation of detailed process screens, trend charts, and animated symbols. The display is protected by a hard‑coated anti‑glare glass. An optional resistive touchscreen is available (not standard on this model).

Keypad and Operator Input

The front panel includes a 28‑key membrane keypad with a numeric block (0‑9), a decimal point, sign, and 16 programmable function keys (F1‑F16) with integrated LEDs for status feedback. The keys have a positive tactile feel and are rated for over 1 million actuations. The keypad is backlit (adjustable intensity) and the overlay is IP65 rated, ensuring resistance to water, oil, and dust commonly found in welding environments.

Communication Ports and Connectivity

• Serial Ports: 2x RS‑232 (9‑pin), one of which can be reconfigured to RS‑485.

• Ethernet: 10/100 Base‑T (RJ45) for network connectivity.

• USB: 1x USB 1.1 (Type‑A) for data export and firmware updates.

• Profibus DP (optional): Plug‑in module for fieldbus integration.

• Printer Port: Parallel (Centronics) for direct printing of process logs.

Memory and Data Management

The PCS950.000.5 is equipped with 4 MB of flash memory for screen storage (up to 1000 screens) and 1 MB of SRAM for variables, recipes, and alarm logs. It supports up to 2000 internal registers (bit, word, double word, float) and 500 alarm messages with historical logging (battery‑backed). Recipe handling allows storage of up to 100 recipe records, each with 200 parameters. A built‑in SD card slot (optional) provides additional storage for data logging and screen backups.

Configuration and Software

The panel is programmed using the LAUER PCS‑Config software (version 5.0 or higher), which provides a comprehensive screen editor, tag database, and communication drivers. The software supports multi‑language text (up to 10 languages) and includes a simulation mode. For Branson‑specific applications, the software includes a library of welding‑related objects (energy, amplitude, pressure graphs). The project is downloaded via Ethernet or serial cable. The panel also supports remote access via VNC (if Ethernet is enabled) for off‑site diagnostics.

Installation and Commissioning

Mount the panel in the control cabinet using the supplied clamps. Ensure the gasket is evenly compressed to achieve IP65 rating. Connect the 24 V power supply (terminal block with screw clamps) – use 1.0‑1.5 mm² wires. Connect the Ethernet and serial cables as required. For first power‑up, the panel will display a start‑up screen and then enter the application. If no application is present, it will show a configuration menu. Use the programming cable to download the project. After download, the panel will restart and run the new application. Check all I/O and communication status via the diagnostic screen.

Maintenance and Troubleshooting

Regular cleaning of the front screen with a soft, damp cloth is recommended. The internal battery (CR2032) for the RTC and SRAM retention should be replaced every 5 years. The unit has a cooling fan (temperature‑controlled) – ensure that the ventilation openings are not blocked. If the fan fails, the panel may overheat; replace the fan unit (field‑replaceable). Common faults: “No Communication” – check Ethernet/serial cable and settings; “Screen Flicker” – check power supply ripple; “Application Not Running” – reload the project. For hardware failures beyond the fan and battery, return the panel to LAUER service.

Compatibility and Ordering

The PCS950.000.5 PG 950.103.0 is compatible with Branson ultrasonic generators (e.g., 2000 series) via the standard communication protocol. It can also be adapted to other PLCs using Modbus or proprietary drivers. When ordering, specify the part number PCS950.000.5 and the desired communication options. Replacement keypads and display protectors are available as accessories.
