Atlas Copco Elektronikon MK5 Controller Operation Guide

The system icon identifies the current user level (basic/advanced/service) and the reset operation entrance. Understanding the meanings of these icons can help quickly determine the operating conditions of the equipment.

Detailed explanation of core menu functions

4.1 Machine Settings Menu

This menu is the most frequently operated area and includes the following subpages:

Setpoint 1 and Setpoint 2 (optional): Used to set the loading pressure (Load) and unloading pressure (Unload). There are usually two sets of settings that can be switched according to gas demand. Select the value when modifying, then adjust it up and down using the vertical slider on the right, confirm and save.

Regulation: The PID control coefficient and pressure band width can be adjusted to affect the response speed of the unit to pressure fluctuations. Generally, the factory default is maintained and only optimized by professionals when special process requirements are met.

Control Mode: Provides three modes: local (panel button start stop), remote (external digital input), and LAN (Ethernet command). After switching, the start stop button on the panel will be activated or deactivated accordingly.

Auto Restart: ARAVF function - when the power failure is restored, if the controller is in automatic operation mode at that time, the unit will automatically restart. This feature is disabled by default at the factory and needs to be activated by entering a password as a Service user. After activation, ARAVF warning labels should be affixed near the unit.

4.2 Auxiliary Equipment Parameters Menu

This menu is only visible to Advanced and above users and is used to configure accessory parameters such as dryer, fan, phase sequence detection, and SmartBox (wireless module). For example:

Dryer: Set the operating mode of the dryer, dew point temperature warning value, etc.

Fan: Configure the start and stop temperature points for the cooling fan.

SmartBox: Used to connect to Atlas Copco's wireless monitoring system and view antenna received signal strength.

4.3 Data Menu

This menu provides read-only information, including three main sub pages:

Counters: Display cumulative values such as total operating hours, loading hours, and motor start-up times, which are the basis for evaluating equipment wear and developing maintenance plans.

Input: List the status of all digital and analog inputs (such as pressure sensor values, temperature sensor values, remote start stop signals, etc.) for easy troubleshooting of external signal faults.

Output: Display the output status of each relay (such as loading valve, unloading valve, alarm output, etc.), used to verify whether the control logic is operating normally. The manual specifically reminds that these voltage free output contacts can only be used for functional control and must not be connected to safety circuits.

4.4 Service Menu

This menu is only visible to Service Users and includes:

Next Service: Display the remaining operating hours until the next maintenance. When the accumulated running time exceeds the set service interval, the service indicator light on the panel will light up.

Reset: After completing the maintenance work, reset the service timer to zero and restart the next cycle. When operating, follow the on-screen prompts to confirm and avoid accidental reset.

Safety Valve Test: Used to record the date of regular testing of safety valves (information only, not automatically executed).

4.5 Controller Settings Menu

Includes general system settings:

Access Level: Switch user levels as described earlier.

Language: Supports switching between multiple languages, and the controller will automatically restart after the change.

Units: Can switch between metric/imperial units (such as bar/psi, ℃/℉).

CAN Settings: Configure CAN bus parameters (if used for multi unit control).

Ethernet Settings: Set the IP address, subnet mask, and gateway for accessing the factory LAN or upper level monitoring system.

Display Timeout: Set the delay for the screen to automatically turn off after no operation, in order to extend the lifespan of the display screen and save energy.

4.6 Information Menu

Provide identification information such as controller firmware version, MAC address, and application software description to facilitate quick provision of device "ID" during after-sales support.

Alarm handling and fault reset

When an abnormality occurs in the unit, the controller will trigger a warning or shutdown. Warning is usually a warning (such as high temperature, high dew point), the machine may continue to operate, but the alarm indicator light will flash. Stop the equipment immediately and lock the start until the fault is resolved and manually reset.

Reset operation process:

Swipe left on the main screen to the Status page. If there is an active alarm, the vertical slider on the right will display the "Reset" icon.

Click on the slider on the right, and a confirmation dialog box will appear on the screen, displaying the reset icon (green check) and cancel icon (red cross).

Click the confirm button and the system attempts to reset. If the fault condition has been eliminated and the alarm disappears, the equipment can be restarted; If the condition is not eliminated and the reset is invalid, the fundamental problem needs to be addressed first.
