On the display
The panel shows Warning - Motor - Oil change required among the warning messages, and this is the only form in which the manual lists it. The message stays on the display until it is manually cleared, or until the operating hours exceed the set hours plus 1,000, at which point the control replaces it with the safety fault Motor - Lack of bearing oil change.
What it means
The motor lubrication interval has been reached: the auto lube type is sleeve and the operating hours since the last motor lubrication have become greater than or equal to 5,000 hours. The warning takes over from the earlier Warning - Motor - Oil change suggested, turning the reminder into a requirement to lubricate the motor. It does not clear itself — it either waits for a manual clear or is replaced by the safety fault Motor - Lack of bearing oil change once the operating hours exceed the set hours plus 1,000.
Why it appears
- Auto lube type is sleeve, and the operating hours since the last motor lubrication are greater than or equal to 5,000 hours.
Setpoints and thresholds
- Warning point: auto lube type is sleeve and operating hours since last motor lubrication are greater than or equal to 5,000 hours.
- Escalation point: the warning is replaced by the safety fault Motor - Lack of bearing oil change when the operating hours exceed the set hours plus 1,000.
- Counter reset: clearing the message resets the operating hours since last lubrication to zero.
Reset and restart
Clearing is done on the Motor Lubrication Screen, where the operator clears the message by entering their initials, name, or user ID using the Motor Lube Acknowledge key. The manual states: You can clear this message by entering your initials, name, or user ID using the Motor Lube Acknowledge key on the Motor Lubrication Screen.
The Motor Lubrication Screen itself gives the entry instructions. When the entry is made, the date and time are automatically logged as the date of last motor lubrication and the time of last motor lubrication, and the operating hours since last lubrication are reset to zero.
