Functional Description

The PCS950Q PLUS membrane keypad is a direct replacement for the original keypad on Lauer PCS950 series operator panels. It features embossed keys for improved tactile feedback, helping operators locate keys without looking away from the display. The keypad includes integrated LED holders for the function key status indicators, ensuring compatibility with the panel's LED driver circuitry.

The keypad is designed for easy installation with a 26-pin flat ribbon cable connector that matches the panel's internal connector. The membrane material is resistant to oils, solvents, and cleaning agents commonly used in industrial environments, ensuring long service life.

Installation and Replacement

Before installation, ensure the operator panel is powered off and disconnected from the power supply. Remove the front overlay or bezel from the panel to access the existing keypad. Carefully detach the flat ribbon cable from the connector on the main board. Remove the old keypad assembly and clean the mounting surface. Position the new PCS950Q PLUS keypad and secure it in place. Reconnect the ribbon cable and reassemble the front bezel. Power up the panel and test all keys for proper operation.

Compatibility and Application

This keypad is compatible with Lauer PCS950, PCS950Q, and PCS950C operator panels. It is also suitable for use in other industrial control panels that use a 36-key membrane layout with the same connector pinout. The keypad is commonly used in machine tool, packaging, and process control applications.

Maintenance and Care

Clean the keypad surface with a soft, damp cloth using mild soap or isopropyl alcohol. Avoid abrasive cleaners that may damage the membrane surface. Inspect the ribbon cable periodically for any signs of wear or damage. The keypad is not user-repairable; if individual keys fail, the entire keypad assembly should be replaced.

Environmental and Safety Compliance

RoHS compliant. The keypad is designed for industrial use in controlled environments.

Technical Support and Documentation

Installation instructions and a pin-out diagram for the ribbon cable are provided with the keypad. Technical support is available through Lauer distributors.

Conclusion

The Lauer PCS950Q PLUS Membrane Keypad is a reliable, durable replacement solution for Lauer operator panels, restoring full functionality and tactile feedback for enhanced operator efficiency.
