None of the Above What You're Experiencing?
The Graco G3 Manual provides information on pump warnings, installation, setup, programming, troubleshooting, maintenance, and more. If you’d rather talk to a person than read a document, we’re always here to help!
LOW LEVEL
What does this mean? The level of lubricant in the reservoir is low and additional lubricant needs to be added. The unit will stop pumping and displays the amount of accumulated time since the alarm was triggered.
How do I fix / reset?
- Add lubricant to the reservoir.
- After lubricant is added, press and hold the RESET button (highlighted) to clear the fault.
- If the repriming pump is required, the low-level alarm time should be decreased. See A-2: Advanced Programming, Low Level Alarm Time on page 51.
PRESSURE WARNING
What does this mean?
The system fails to relieve pressure in the user-defined amount of time.
The unit will continue to operate for the number of lubrication cycles set by the warning retry parameter. See Advanced Programming, page 49.
If the warning condition clears itself on the next lubrication cycle, the warning is cleared and the unit continues normal operation.
How do I fix / reset?
- Examine the system to determine if you have a plugged or broken line or other component failures i.e., divider valve and injector.
- Press the RESET button (highlighted) to clear the warning.
CYCLE FAULT
What does this mean? The cycle mode indicates a cycle was not completed in the user-defined amount of time.
LED corresponding to the affected sensor input will blink. This could be a warning of one sensor alarm being triggered at the same time.
How do I fix / reset?
- Examine system to determine if you have a plugged or broken line or other component failure i.e., divider valve and injector.
- Press the RESET button (highlighted) to clear the warning.
