Atlas Copco 1900071162 Operator Interface Panel

The Atlas Copco 1900071162 is a dedicated operator interface panel designed for use with Atlas Copco control systems, particularly those in the 1900 series. This unit combines a high‑contrast graphic LCD with a tactile membrane keypad, allowing operators to view system parameters, adjust setpoints, acknowledge alarms, and navigate menus without requiring a separate computer. It is commonly used in compressor controllers and tightening systems for local human‑machine interaction.

Display and Keypad Features

The display is a 128 x 64 pixel monochrome LCD with white LED backlight, ensuring clear visibility even in dimly lit industrial environments. The backlight intensity can be adjusted via software. The keypad consists of 16 keys, including numeric 0‑9, enter, escape, and arrow keys, all with tactile feedback. The overlay is made of durable polyester, resistant to oils and mild solvents.

Technical Specifications

• Supply Voltage: 5 VDC or 24 VDC (depending on interface cable)

• Communication: RS‑232 or RS‑485, baud rate 9600 to 115200

• Display Size: 2.8″ diagonal

• Keypad Life: > 1,000,000 actuations

• Protection: Front IP54 (splash and dust resistant)

• Operating Temperature: -10 °C to +60 °C

• Dimensions: 110 x 65 x 25 mm (W x H x D)

• Mounting: Panel cut‑out, with included gasket and clips

Integration with Controllers

The panel communicates with the host controller via a simple serial protocol, requiring only a four‑wire connection (power, ground, transmit, receive). It is pre‑programmed with standard menu structures for Atlas Copco compressors and tightening controllers, but can be customised using the controller’s configuration software. The panel automatically adapts to the connected controller’s language settings.

User Interface Functions

Operators can use the panel to:

• View real‑time process values (pressure, temperature, torque, angle)

• Change operating modes (auto/manual/remote)

• Adjust setpoints (target torque, pressure band)

• Reset alarms and faults

• Monitor cycle counters and maintenance reminders

• Access diagnostic logs

The panel also supports password‑protected access levels to prevent unauthorised changes.

Installation and Configuration

Installation involves cutting a rectangular hole in the control panel door, inserting the unit, and securing it with the provided clips. The interface cable is connected to the controller’s serial port. Configuration is done via the controller’s software, where the user can assign specific values to the function keys and customise the display screens.

Reliability and Environmental Resistance

The 1900071162 is built to withstand industrial conditions, with a robust front overlay that resists scratches and chemical attack. The internal electronics are conformally coated to protect against humidity and dust. The panel has no moving parts, ensuring long‑term reliability. Mean time between failures is estimated at over 50,000 hours.

Applications

This interface panel is used in stationary and portable air compressors, as well as in tightening workstations that require a local display. It is particularly useful in remote locations where a full PC is impractical, or as a backup interface for maintenance tasks.

Maintenance

No routine maintenance is required beyond cleaning the display with a soft, dry cloth. If the keypad becomes unresponsive, the panel can be replaced quickly without affecting the controller’s settings. Spare units are available as standard parts.

Benefits

By providing a dedicated local interface, this panel enhances operator convenience and reduces dependence on external computers. It also speeds up troubleshooting by giving immediate access to alarm codes and system status. Its compact size allows it to be fitted into tight control panels.

Conclusion

The Atlas Copco 1900071162 operator interface panel offers a reliable, cost‑effective solution for local monitoring and control of Atlas Copco systems. Its intuitive layout, robust construction, and simple integration make it a valuable addition to any controller installation.
