Atlas Copco 1626850006 Controller Panel (1626‑8500‑06)

The Atlas Copco 1626850006, also designated 1626‑8500‑06, is a fully integrated controller panel designed for Atlas Copco stationary and portable air compressors. This panel serves as the central command unit, housing a graphical user interface, programmable logic controller, and power distribution circuitry. It is engineered to provide intuitive monitoring and control of all compressor functions, including pressure regulation, motor management, and fault diagnostics.

Panel Construction and Layout

The panel is housed in a rugged steel enclosure with a powder‑coated finish, rated to IP54 for protection against dust and water splashes. The front face features a backlit 128x64 pixel LCD display with a 16‑button membrane keypad for navigation and parameter entry. Inside, the panel contains a main processor board, power supply module, relay outputs, and isolated input terminals. All wiring is clearly labelled and routed through cable glands on the bottom side.

Display and User Interface

The LCD screen shows real‑time readings of discharge pressure, air temperature, motor current, and running hours. It also displays alarm and warning messages with plain‑text descriptions, enabling quick troubleshooting. The keypad allows operators to set pressure bands, adjust timers for auto‑start/stop, and configure communication parameters. The interface supports multiple languages and can be customised for specific compressor models.

Technical Specifications

• Supply Voltage: 24 VDC (from internal transformer or external source)

• Inputs: 8 digital (24 VDC) and 4 analog (0‑10 V or 4‑20 mA)

• Outputs: 6 relay (2 A @ 250 VAC) and 2 analog (0‑10 V)

• Communication: RS‑485 Modbus RTU, optional Ethernet module

• Display: Graphic LCD, 128x64, white LED backlight

• Memory: 2 MB flash for program and data logging

• Operating Temperature: -10 °C to +55 °C

• Dimensions: 250 x 200 x 80 mm (W x H x D)

Control and Protection Functions

The panel manages all essential compressor operations: automatic load/unload based on pressure setpoints, motor soft‑start and stop, and sequential control for multiple compressors. Protection features include over‑pressure shutdown, motor overload monitoring, phase loss detection, and high‑temperature alarm. The controller also supports emergency stop integration and can interface with external safety relays.

Data Logging and Remote Monitoring

Built‑in data logging records the last 100 events (alarms, power cycles, setpoint changes) and stores daily averages of key parameters. These logs can be retrieved via the serial port or optional Ethernet for maintenance analysis. The panel is compatible with Atlas Copco’s remote monitoring software, enabling off‑site access to real‑time data and fault notifications via email or SMS.

Installation and Commissioning

Installation involves mounting the panel on a control cabinet door or wall, connecting power and sensor cables, and grounding. Commissioning is performed through a guided wizard that prompts the user to enter motor data, pressure transducer calibration, and network settings. A built‑in test mode verifies all I/O connections before putting the compressor into service.

Compatibility

This controller panel is designed for Atlas Copco GA, GR, and Z series compressors, as well as portable units like XA and XR. It can also be used as a replacement for earlier 1900 series panels, offering improved processing speed and larger memory. The panel’s firmware can be updated via USB to support new features or compressor variants.

Reliability and Maintenance

With solid‑state components and no internal batteries, the 1626850006 offers long‑term reliability. Routine maintenance involves checking terminal tightness and cleaning the display. The panel has a mean time between failures exceeding 80,000 hours. Spare parts, including keypad overlays and fuse holders, are available through Atlas Copco’s service network.

Application Examples

This controller is used in manufacturing plants, mining operations, construction sites, and anywhere reliable compressed air is required. It provides operators with immediate access to system status and enables quick adjustments to changing demand, thereby reducing energy waste.

Conclusion

The Atlas Copco 1626850006 controller panel offers a robust, user‑friendly solution for air compressor management. Its comprehensive feature set, ease of installation, and seamless integration with existing Atlas Copco equipment make it a trusted choice for maintaining optimal compressor performance and uptime.
