Atlas Copco Elektronikon MK5 Controller Operation Guide

Manual strongly warns: Do not repeatedly reset the alarm without solving the root cause, otherwise it may cause serious damage to the equipment. For example, if the exhaust temperature is too high and causes a shutdown, the cooling system, environmental ventilation, or temperature control valve should be checked first, and then reset after the temperature drops to normal.

Enabling and Risks of Automatic Restart (ARAVF) Function

ARAVF is highly valuable in unmanned or remote stations, but it must be used with caution. Its activation requires Service permission and password. Specific steps:

Go to the Machine Settings → Auto Restart page.

Change the option from 'Disabled' to 'Enabled', and the system prompts for a password.

The function takes effect after entering the correct password.

After activation, if the controller shuts down due to power interruption, when the voltage is restored and the controller is in "automatic" mode, the unit will start automatically without manual intervention. This means that maintenance personnel must manually switch the controller to the "local" or "stop" state during maintenance, otherwise accidental power transmission may cause the compressor to suddenly start, resulting in personal injury. Therefore, the manual explicitly requires that an ARAVF warning sign must be affixed near the controller after activation.

Daily operation skills and maintenance suggestions

Parameter modification confirmation: After any numerical modification, be sure to click the "V" on the horizontal slider to confirm, otherwise the modification will be invalid. If you want to give up, click "X" to cancel.

Screen cleaning: After turning off the power, use a soft dry cloth to wipe and avoid using organic solvents.

Regularly check the input/output status: Observe whether the sensor readings are reasonable through the Data menu, such as whether the pressure transmitter is drifting or the temperature probe is open circuit.

Service timer management: It is recommended to set reasonable intervals according to the manufacturer's maintenance schedule (such as replacing oil filters, air filters, and oil separation cores), and reset the timer after each maintenance to ensure accurate reminders.

Firmware upgrade: It can be done through Ethernet or USB, but it needs to be operated by an authorized service provider to prevent version incompatibility.

Common problem troubleshooting quick search

Possible causes and measures for handling the phenomenon

The screen shows no display, the power supply is not connected or the fuse is blown. Check the main power supply and control transformer fuse

Press the start button to switch from remote or LAN control mode to local mode or check remote signal without any response

Frequent loading/unloading of pressure bands with narrow settings or large gas fluctuations, appropriately relaxing the pressure band values or checking for leaks in the pipeline network

The service light is on, reaching the maintenance time. Perform maintenance and reset the timer

Alarm cannot reset. Actual parameters still exceed the measured actual temperature/pressure. Reset after troubleshooting

Ethernet communication failure, IP setting error or network cable failure. Check IP/subnet/gateway and test physical connection
