Description

Siemens PXM20 Operator Panel

Product Dimensions：

The Siemens PXM20 is a high-performance operator unit designed for the Desigo™ PX building automation and control system. It provides a localized interface for monitoring, operating, and configuring PX automation stations without the need for a central PC or complex software.

Product Detailed Description

The PXM20 serves as a powerful, field-level user interface. It features a high-resolution backlit display and a simplified keypad that allows building managers or technicians to interact directly with the building management system (BMS). It can be mounted directly onto the front of a control cabinet or used as a handheld device for mobile commissioning and maintenance.

Technical Parameters

Product Advantages

• User-Friendly Navigation: Uses a consistent “Rotate-and-Push” logic (via the navigation knob and keys) for intuitive access to complex menus.
• Full System Visibility: Allows users to view and acknowledge alarms, change setpoints (e.g., temperature), and manually override schedules or plant states.
• Multi-Language Support: Supports multiple operating languages, which can be toggled depending on the user’s preference.
• Graphical Feedback: Provides trend graphs and bar charts directly on the small screen to visualize sensor data over time.
• Plug-and-Play: When connected to a Desigo PX station, it automatically uploads the plant structure and data points for immediate use.

Important Considerations & Precautions

• Compatibility: Ensure the PXM20 firmware version is compatible with the Desigo PX automation station firmware (e.g., PX Compact or PX Modular).
• Connection Distance: The PPS2 interface has a maximum cable length (typically up to 3 meters for the standard cable). For longer distances, specialized wiring or different interface modules may be required.
• Power Supply: The unit is typically powered by the automation station it is connected to; ensure the station has sufficient power overhead to drive the backlit display.
• Cleaning: Use only a soft, dry cloth to clean the display. Harsh chemicals or abrasive materials can damage the LCD screen and the membrane keypad.

Product Applications

The PXM20 is found in various building automation scenarios:

• HVAC Control: Monitoring air handling units (AHUs), boilers, and chillers within a mechanical room.
• Local Maintenance: Serving as a diagnostic tool for technicians to troubleshoot a specific automation station during routine service.
• Room Automation: Adjusting lighting, blinds, and climate settings in large commercial spaces or auditoriums.
• Emergency Override: Providing a physical interface to manually force fans or pumps “On” or “Off” in the event of a network failure at the supervisory level.
