Warning messages for oil separator filter maintenance
A counter, operating via the NC, determines the effective machine work hours. 2800 hours after
the last intervention, a message appears on the screen to tell the operator to replace the filtering
element within the time indicated.
PLC9788>Replace the oil separator filter (refer to the User Manual) within x hours
This message will continue to appear until the end of the specified time. If the element is not
replaced within the 3000 hours envisaged, a new message will appear:
PLC9787>Replace the oil separator filter (refer to the User Manual)
This message will remain visualised until the filtering element has been replaced.
Reset procedure
After replacing the filtering element, you can eliminate the warning message and reset the
counters.
Proceed as follows:
• open the technical data
• enter the password for the administrator user level (level 7)
