The MAM860 (IV) is an oil-free scroll air compressor controller designed for intelligent automatic operation of air compressors. It features a microcomputer controller that enables automatic pressure control, real-time display of failure messages, protection shutdown, and networking group control. The LCD screen displays four lines of text, allowing operators to set parameters and monitor the compressor's operating status through a user-friendly interface.

Function Description:

The controller manages various aspects of the air compressor's operation, including starting and stopping, loading and unloading, and monitoring critical parameters like temperature, pressure, and current. It supports both single-host and double-host operation modes, offering flexibility in deployment.

Key Functions:

• Start/Stop Control: The "Start key" initiates operation when the compressor is in standby mode or, in connection mode, starts the host compressor and activates connection control. The "Stop key" halts operation when the compressor is running or, in connection mode, stops the host and connection control. A long press of the "Stop key" in shutdown state displays software version information.
• Load/Unload Control: The "Load/Unload key" (S) functions as a load/unload key when the compressor is running. In setup mode, it serves as a confirmation key to save input data.
• Navigation and Data Modification: The "Down key" and "Up key" are used to move the scroll bar when viewing parameters. When modifying data, they act as "Dec key" and "Inc key" respectively, to decrease or increase the flashing data value.
• Menu and Setup Access: The "Shift key" (►) moves the blinking cursor to the next bit during data modification. As an "Enter key," it accesses lower-level menus or enters setup mode if no lower-level menu exists, causing data to flash.
• Return and Reset: The "Return key" (C) exits setup mode, returns to the previous menu, or the main interface. A long press (5 seconds) of this key resets faults during a fault shutdown.
• Automatic Operation: The controller provides automatic pressure control, ensuring the compressor operates within desired pressure ranges.
• Fault Management: It displays real-time failure messages and initiates protection shutdowns when necessary.
• Networking Group Control: The controller supports connecting multiple air compressors for coordinated operation, with one serving as a host and others as slaves, managing start, stop, loading, and unloading based on air pressure.
